🥳Some Updates 🥳 • I've added some more languages as audio tracks by popular demand: French, Ukrainian, Turkish, and Polish • I've also improved the subtitles script so that should smooth out the dubbed speaking speed, so there should be fewer speed-ups and slow-downs in speaking, let me know what you think.
I am more than surprised hearing my native language in your video. I personally choose to listen to original audio but want to say thank you so much for making your videos more and more accessible.
You added my language, so I can finally see how this works. It's pretty good, but misses plus, so its like "SFP might not be compatible with SFP" (english version had SFP+)
Can’t count how many times I’ve seen these connectors on an LTT video. That’s where I first saw them and now expect that a server chassis will support them. 😅
Hi Thio. Your YT script for translating and dubbing it on another language is awesome. So many people can enjoy your content even without knowing English. Just a heads up: In my native language (Brazilian Portuguese) "RJ45" are being translated as "Rio de Janeiro 45". I don't know how you can fix this since is an auto translation issue, but it messes with the timing of dubbed lines.
Those are common connectors for me. They are used for every installation for fiber optic internet in Canada and since I worked as phone support for those connections, I have become very familiar with them
@@Tanks_In_Space I had to learn about them as customers regularly didn't know how to take them out and one of our steps was to have the customer remove the cable. I take every opportunity to learn hands on then that way I can instruct people over the phone as I can picture it in my head and give very detailed explanations. OH WHAT FUN THAT WAS.
It is about 20 years ago by now, but they look like those optical thingys I stuck into a switch in the early 2000’s to connect a fibre pair when I was a server/network admin. I have been out of that kind of business for about 15 years, so I don’t remember exactly how they looked.
I used to use them a few years ago, when I was doing some work for Allstream. I'd be in a data centre, with the fibre connecting to a Ciena media converter and then copper to a Cisco router, which the customer then connected to. The SFP had to match the fibre type and wavelength for the connection.
"never look into the end of a fiber cable". THANK YOU for this warning! I have no occasion to walk into datacenters, but this may happen and I could be tempted to do it... now I know! This made my day.
Anyway - we do have quite a number of those devices at work. Mostly multimode. The light in the multimode transcievers is actually visible if you use your phone camera, it helps quite a lot when you try to figure out which side that's the dark side.
@@pyp2205 i use them at home... because i can. i used to have 4 rj45 from my adsl router until i bought a 5g adsl version. it has 4 rj45 and one sfp+ port. so me being me, i got rid of the 4 rj45 and replaced it with one fibre optic to sfp+ connector to my L2 home network switch.. lets just say i can see a combined throughput of over 200mb/s to the router...
As worked with fiber optics in Telecommunications, just a pro tip. Never look directly into the tip of the fiber cable connected to any equipment (specially industry/corporate grade) . Power ranges of these equipment can be easily in range of above +20 db and that invisible light running through that fiber can burn your fingers let alone fry your eyeballs if looked directly, you can literally see sparks through the plastic tip if touched to a cleaning cloth dipped in alcohol.
A couple years ago I bought a QNAP TS-332X Home NAS specifically bc it came with the 10GbE SFP+ port. Added an inexpensive, older generation 10GbE PCIe card to my workstation, and connected to NAS via a copper "TwinAx" cable. Paid $35 for the PCIe card and cable on eBay.
what do you mean? This are just data links and have nothing to do with loadbalancing. This is the physical layer of the osi model. Loadbalancing it way more up in the model.
I have 4 Ubiquiti 10 port EdgeSwitches. 2 of the 10 are SFP cages. So, I bought 8 1000BASE-T copper transceivers, because I wanted to be able to use all of the ports if needed. I was surprised at the amount of heat that was coming off of the SFP modules. I read that they can get hot. But geeezzz! I recently bought a Grandstream GWN7803 (28 ports in all) L2 switch, which includes 4 SFP cages. They're nice to have, if you need them.
A sfp module exist either as rj45 or as fibre. That is the sense of this module that you can decide self if you need copper or fibre. It depends on length of cable. Copper cannot bridge more than 100m. You will need it on each cisco switch and some of commodity. And PoE is availabe, that is the sense of SFP+, it delivers 60 watts instead of 30 of normal sfp.
We have just upgraded our server and switches where I work which is about 250 feet +- between the switches. With that we were already having CPU and Disc usage issues bumping up to %100. Our IT company said we needed these for the longer runs. Since we run our own lines, we needed to know what these were and how to assemble them. Thanks because this was perfect for us. Passed it off to my boss and he was thankful as well.
These modules have another thing to check - the cable length. Some models officially support shorter runs than expected 100 meters, it can be as short as 30 meters instead.
0:21 Oi, a tradução meio que levou ao literal o RJ45 como “Rio de Janeiro 45” (pois a sigla do estado no Brasil é a mesma), as pessoas geralmente falam “RJ45” no português.
Also, consider different optical transmit power and attenuators. I recently had a customer who had connection problems with their SFP because the fibre was only a few meters but the switch was rated for 20kms. The optical receiver can be damaged without an attenuator.
Was super disappointed with the ubiquiti unit. Didn’t support negotiating at speeds under 1gbps. Just needed to add one more port, didn’t need a small dummy switch. Turns out I needed a dummy switch
Not all ONU's are made like that. Zhone has models where the transceiver has to be installed, and plugs into an LC connector which than plugs into a terminated SC connection inside the enclosure where the fiber loop is
they're expensive compared to the much more common 1Gb (or even 2.5Gb) switches but for 5 or 10GbE the mikrotik switches with all SFP+ ports are among the cheapest you can get by far. In fact, I wish consumer grade multigig would move to SFP+ instead of RJ45 because of this exact reason. Everytime I have to connect something RJ45 especially at multigig speeds, the switches i have to get are triple the price.
Well, being a telecom engineer I use SFPs daily :-) Of course I knew the most you said, but still it was interesting to me. I can add that not only SFPs can be incompatible with your equipment, they can be different at all, like Ethernet SFP, used for switches, of STM SFP, used in telephony connections. They also can use separate fibers for transmission and receiving data, as well as they can use single fiber, but use different wavelength signals for different directions. SFP-to-Ethernet is what we use for switches that have SFP ports only and we need to connect it to "copper" equipment.
Great to see the language feature at work again! Just a heads up for future translations. You may want to use the ISO 4217 standard codes when talking about currencies, so it doesn't interpret '$' as a different currency.
I've been lucky to be able to work with QSFP-DD (and soon OSFP), It is really cool tech and incredibly fast data rates, even considering that the 400G is divided across 8 channels. My company is making equipment for Cisco, Juniper, et al to test the electromagnetic radiation of their QSFP-DD hardware. When you have a server rack full of these modules, its basically a wall/array of antennae radiating at up to 50GHz, and neighboring racks can interfere with each other if not shielded properly.
Correction: at 1:50 you show a chart of latencies between connections and say that "SFP has lower latency than RJ45" Which isn't accurate to the chart. The left column shows "10GBaseT SFP" Which is an rj45-sfp adapter, not direct rj45-rj45(technically 8p8c but that's besides the point). It is the adapter from the rj45 to SFP that is causing the increased latency, vs "direct attach copper", pure sfp to sfp no adapter. I've yet to see any evidence that pure SFP DAC has lower latency than pure RJ45, and at least one video on youtube suggests the opposite.
The old timers I work with use the anachronistic term "gbic" to refer to SFPs. We have a wide variety of clients at our MSP. We recently installed a commercial StarLink dish at a rural client site as a secondary WAN. Being that this site has had several lightning strikes I opted to use a media converter to connect the RJ-45 from the starlink to the secondary WAN SFP port on their UDM Pro. Better to have a measure of electrical isolation than have their main router take a lightning strike again. I dug a burnt cable out of the wall when I ran the line too. 🤣🤣
"Rare use case"? As a home lab user, I've got a DAC between my NAS and switch and budget server and switch, so both have a 10G connection to each other.
The compatibility issue you saw is strangely sinister. Inside the sfp chipset is data containing serial number, manufacturer, etc. Network gear manufacturers sometimes hard code their devices to look for only their own sfp’s. Most of the big enterprise players have a command to tell their equipment not to do that, but after you run that command, their support will stop at the sfp port level. Also, your example 10gig throttling down to 1gig is simply because the equipment is inexpensive and doesn’t have enough queue memory to slam 10gig frames at a 1 gig port. This used to be common behavior, even on enterprise gear, back when nothing had enough queue size.
I use these all the time both at work and at home and at my friends and families houses too. I've got a 10GB NIC for my desktop to interface to my fiber internet to get my advertised speeds from my ISP. I'd like to use fiber but the router from the ISP only has a 10GB copper jack 😞
adoro il tuo software per tradurre i video, è molto utile per i video classici ma per i Roleplay è un casino, ci vorrebbe di migliorare il file aggiungendo le varie emozioni in modo che possa emularle
I used the SFP+ when I was working for an ISP. One coming in from each of the backbone providers, into the transparent firewalls that I built and ran for the ISP. And then one each going out of the firewalls, and again one each going into the big Cisco router. I think that we also had a few going from the router into the big switches.
"...totally overkill for a home use..." I trunk VLANs (between switches) over multi-mode fiber at home - and have a set of spare copper SFPs for use on UTP cables parallelling the fiber if something goes bad.
also bare in mind if you do this on more switches then spanning tree or it's new rstp versions comes into play. Basicly have redundant pathes in the network (which is a big no no in ehternet) and the spanning tree blocks them so no loop ocours and if a link goes down spanning tree will recalculate and enable a redundant link.
@@alexanderg9106: The copper SFPs are spares - only one SFP can be plugged in at a time anyway, and I have them so no other port configuration needs to be changed to swap between SFP media types. There is only one trunked port coming in to any of my peripheral switches.
@@alexanderg9106: And rather than getting fancy with redundant links and equipment, I just swap out failed parts (I have spare switches for everything I run) - It is a home environment after all. 😁
The technology behind automatic translations is impressive, but the audio speeding up and down to match the original speed is kinda weird sounding. Also it seems like sometimes it's just translating word by word rather than full phrases and it ends up with a phrase that doesn't quite make sense in Polish, but I was surprised how it handled proper nouns.
Even with DACs, you can run into issues when you mix and match vendors. The host device (device with SFP port) and the SFP itself always perform a negotiation, even if there's no actual logic needed for transceiving the signal (because it's just a copper cable). Some devices are more picky than others, on some switches you have to enable a config option to allow unsupported transceivers (ones from a different brand than the switch). Using SFPs from a generic brand can be hit and miss. There's one brand, they're called Flexoptix out of Germany that offers programmable universal transceivers that can be programmed to emulate the behaviour of any other SFP, they mostly work well in my experience. And they're hella cheap compared to the official vendor ones - an original Cisco SFP might literally be 10x the price of a reprogrammable Flexoptix SFP. Then again, the box used to reprogram SFPs is something like 1,5k, so only affordable to businesses that do a lot of installations.
Its just an SFP. We use them all the time in Enterprise switches for connecting fiber and far less less commonly RJ-45. I have a Cisco switch in my room and it has 4 SFP slots. I was planning on running fiber from my room to the router to replace the existing Ethernet over Coax and I would use SFPs on both ends.
Use it at home to run fiber setup from 1st floor to basement, as of now just a single converter in between to go from modem to Ethernet converter to converter to Ethernet and attached to router in basement for now with wifi turned off getting switch tomorrow to make it better in terms of that comes sfp too
Excellent video : I have a quick question, Can we connect QSFP to ethernet directly or do we need to convert QSFP to SFP+ and another convertor from SFP+ to Ethernet?
When installing AV over IP encoders and decoders, sometimes all the ports become used, the bandwidth or power allowance is maxed out, so we have to stack switches to either increase the bank or add extra ports to the installation.
and here I am, trying to get 2.5 gig to the entire house, and this switch I bought is 4 2.5 gig ports and 2 SFP+ ports... sure hope I can circle chain a few together
I hate the fact the audio track gets chosen automatically, even if I want to watch it in the original language. TH-cam did a bad job at implementing it.
I'm sometimes being in an area with a switch rack. I examined the switches inside that and noticed that most of them were not looking like the Ethernet cable plugs I know. Some plugs(maybe) had two cables attached to them. I guessed that there could be fiber there, but I didn't know much idea. Now I know that the rack was full of SFP's 🤯
I have a 10G leg of my LAN that supports my desktop computer, my music (composing and creation) computer and server (a Dell Edge R720). I use 10G because I try to work exclusively from files stored on the server which, in turn, back is backed up to three NASes (back in the 80s I lost a fair bit of data in a crash -- that will never happen to me again!). I also have a couple of switches that are 10G in and 1G out scattered throughout our apartment. This guarantees that I'll never run out of bandwidth. For example- my wife and I can watch different movies in different rooms without overtaxing the switches. Incidentally, I also ran into the exact same problem with that Netgear switch. I changed it out with a comparable Ubiquiti switch and the problem vanished. I have a Ubiquiti DMPro and a Ubquiti aggregator. Almost everything there is SFP+ to copper, though I do use a couple of SFP+ RJ45 adapters. By the way, though I'm pretty good with the stuff, I always learn something from your videos! Keep up the great work!
I have often used those, when setting up connections from a carrier to a data centre. With fibre, there are a variety of models, depending on the fibre connection. There can be single or double fibre versions, single or multimode and any of those with a variety of wavelengths (infrared "colour") to consider. Also, you showed a switch with several copper connectors and 2 SFP connections. When there are 2 or 4 connections, separated from the rest of the switch, they're generally used for upstream connections and will typically be faster than the rest of the switch. For example, years ago, I used to work with 24 port 100 Mb switches, that also had 2 Gb ports. Those Gb ports could be connected to a Gb switch, for large networks. The same holds with the speeds commonly found these days.
I’ve never seen an SFP for $10 or an SFP+ for $50 but that’s because we pay Cisco’s nonsense pricing where an SFP is almost $700 and an SFP+ is $1100 for single mode 10GBaseLR. Their QSFP28 units are $6000
I have a whole home network setup with a TrendNet 24-1GB and 4 SFP+ ports. I have one sfp port for my Pc at 2.5Gbps and 2 for my Synology DS1618+ duel 10Gbps (Aggregated) to equal 20Gbps. It works very well with the SFP+ and RJ45 adapters.
It auto switched to polish for me and I have to say, it's pretty amazing that you can do that now, but the constantly changing speed of the narrator is sometimes distracting. I feel like inserting a bit of a pause instead of slowing down the speech might be a good idea in some cases to make it "flow" better. There are some mistakes/things translated "too directly" where some context changes the word we would use in polish, but it's usabe. I still prefer to watch in english, but that was to be expected as I can hear the original in sync with the video and without any mistakes. Really nice!
You say that folks haven't seen it before, but I bought an RJ45 to SFP+ transceiver recently with the expectation that no one else would buy the remaining stock by the time I wanted a second one, but no. Out of stock.
When I was in the military we had a connector that had about 120 pins in the connector and could transfer almost a terabyte of information in less than a minute however this requires a special setup to work properly and even then it's not particularly easy to use or get maximum speeds during transfer.
I have to plug in one of these SFP+ adapters for my modem's fiber internet connection. There is one 10 GbE port on my modem, which I can break out to other devices using a 10 GbE switch. I use a TP-Link TL-SX105 for this purpose.
My ISP modem has this to connect the fiber optic cable into it. It was back in 2020 when I got their newest modem I think, it was the first time I saw that thing, so yeah, I saw that thing before! Oh, and it's pretty funny hearing French speeding up and slowing down suddenly, at least it works ^^
I literally got to know these from the LMG vids. For those who don't know, LMG Stands for Linus Media Group & it's the company headed by Linus Sebastian which has YT channels LTT(Linus Tech Tips), Techquickie, Short Circuit, etc.
Last month I also added 10G to my Synology and pc. I use mellanox x3 cards from AliExpress with a qnap qsw-m408-2c switch which has 4 10G ports and 8 1G ports, of which 2x 10G combo ports. Next switch is a qnap qsw-1108-8t to living room and router which is 2.5Gbit.
The problem might be with your 10g pc connection to the switch and then onto the Apple TV. You might be running into issues with the larger data frames and packet sizes in 10gb. On the pc you could match the transmit and receive buffer to that of a 1g connection. I have run into this problem before with NDI
Is there a way to turn the automatic change to the voicetrack off or so I need to change my youtube language to english? Because it is already starting to annoy me...

Inside the sfp chipset is data containing serial number, manufacturer, etc. Network gear manufacturers sometimes hard code their devices to look for only their own sfp’s. Most of the big enterprise players have a command to tell their equipment not to do that, but after you run that command, their support will stop at the sfp port level.
Also, your example 10gig throttling down to 1gig is simply because the equipment is inexpensive and doesn’t have enough queue memory to slam 10gig frames at a 1 gig port. This used to be common behavior, even on enterprise gear, back when nothing had enough queue size.
I use these all the time both at work and at home and at my friends and families houses too.
I've got a 10GB NIC for my desktop to interface to my fiber internet to get my advertised speeds from my ISP. I'd like to use fiber but the router from the ISP only has a 10GB copper jack 😞
There's even VDSL2 Modems for SFP form factor so you can plug your DSL directly into your router/switch.
adoro il tuo software per tradurre i video, è molto utile per i video classici ma per i Roleplay è un casino, ci vorrebbe di migliorare il file aggiungendo le varie emozioni in modo che possa emularle
I used the SFP+ when I was working for an ISP. One coming in from each of the backbone providers, into the transparent firewalls that I built and ran for the ISP. And then one each going out of the firewalls, and again one each going into the big Cisco router. I think that we also had a few going from the router into the big switches.
In some places, you can get 10Gbps residential internet these days :)
@@ArthursHDyou probably can, but not where I live. You are still lucky to have 10Mbps service, unless you are on StarLink.
You mentioned Latency, every FPS/RTS player will now rush and buy one :D
Maravilhoso conteúdo, obrigado por trazer em Português do Brasil🇧🇷
good one, the last video before bed and clearest i watched :)
"...totally overkill for a home use..."
I trunk VLANs (between switches) over multi-mode fiber at home - and have a set of spare copper SFPs for use on UTP cables parallelling the fiber if something goes bad.
also bare in mind if you do this on more switches then spanning tree or it's new rstp versions comes into play. Basicly have redundant pathes in the network (which is a big no no in ehternet) and the spanning tree blocks them so no loop ocours and if a link goes down spanning tree will recalculate and enable a redundant link.
@@alexanderg9106: The copper SFPs are spares - only one SFP can be plugged in at a time anyway, and I have them so no other port configuration needs to be changed to swap between SFP media types. There is only one trunked port coming in to any of my peripheral switches.
@@alexanderg9106: And rather than getting fancy with redundant links and equipment, I just swap out failed parts (I have spare switches for everything I run) - It is a home environment after all. 😁
I’ve actually seen some of these in old switches at my secondary school today! It had a fiber connection. Also seen two QSFP+ cables in the IT room.
7:46 i would recommend a MikroTik CSS326 (?) with 2 SFP+ and 24 RJ45 Ports for around 160€
this video is pretty interesting.
by the way, i hope you get to 3 million subs.
The technology behind automatic translations is impressive, but the audio speeding up and down to match the original speed is kinda weird sounding. Also it seems like sometimes it's just translating word by word rather than full phrases and it ends up with a phrase that doesn't quite make sense in Polish, but I was surprised how it handled proper nouns.
excelente tutorial saludos desde Colombia
With old tech I just try not to hit my head against a brick wall😂
ThioJoe in Portuguese you have to use
R J45 because if you use RJ45 the voice on the video will say "Rio de Janeiro 45"
Even with DACs, you can run into issues when you mix and match vendors. The host device (device with SFP port) and the SFP itself always perform a negotiation, even if there's no actual logic needed for transceiving the signal (because it's just a copper cable).
Some devices are more picky than others, on some switches you have to enable a config option to allow unsupported transceivers (ones from a different brand than the switch).
Using SFPs from a generic brand can be hit and miss.
There's one brand, they're called Flexoptix out of Germany that offers programmable universal transceivers that can be programmed to emulate the behaviour of any other SFP, they mostly work well in my experience. And they're hella cheap compared to the official vendor ones - an original Cisco SFP might literally be 10x the price of a reprogrammable Flexoptix SFP.
Then again, the box used to reprogram SFPs is something like 1,5k, so only affordable to businesses that do a lot of installations.
This is so weird hearing a Polish narrator over ThioJoe on autoplay xD
Its just an SFP. We use them all the time in Enterprise switches for connecting fiber and far less less commonly RJ-45. I have a Cisco switch in my room and it has 4 SFP slots. I was planning on running fiber from my room to the router to replace the existing Ethernet over Coax and I would use SFPs on both ends.
Use it at home to run fiber setup from 1st floor to basement, as of now just a single converter in between to go from modem to Ethernet converter to converter to Ethernet and attached to router in basement for now with wifi turned off getting switch tomorrow to make it better in terms of that comes sfp too
Hello 👋🏻 Happy New Year 🎆
Excellent new year, good to be back
@@ThioJoe 🥳🎉
I gave the video the biggest thumbs-up I could find!
Excellent video : I have a quick question, Can we connect QSFP to ethernet directly or do we need to convert QSFP to SFP+ and another convertor from SFP+ to Ethernet?
Good stuff. I use fiber SFP, SFP+ and DAC and some RJ45 transceivers for 10G. Still, I learned some stuff today. Thanks.
Was waiting for the next video to check out the audio tracks.
When installing AV over IP encoders and decoders, sometimes all the ports become used, the bandwidth or power allowance is maxed out, so we have to stack switches to either increase the bank or add extra ports to the installation.
and here I am, trying to get 2.5 gig to the entire house, and this switch I bought is 4 2.5 gig ports and 2 SFP+ ports... sure hope I can circle chain a few together
I hate the fact the audio track gets chosen automatically, even if I want to watch it in the original language. TH-cam did a bad job at implementing it.
I'm sometimes being in an area with a switch rack. I examined the switches inside that and noticed that most of them were not looking like the Ethernet cable plugs I know. Some plugs(maybe) had two cables attached to them.
I guessed that there could be fiber there, but I didn't know much idea.
Now I know that the rack was full of SFP's 🤯
I have a 10G leg of my LAN that supports my desktop computer, my music (composing and creation) computer and server (a Dell Edge R720). I use 10G because I try to work exclusively from files stored on the server which, in turn, back is backed up to three NASes (back in the 80s I lost a fair bit of data in a crash -- that will never happen to me again!). I also have a couple of switches that are 10G in and 1G out scattered throughout our apartment. This guarantees that I'll never run out of bandwidth. For example- my wife and I can watch different movies in different rooms without overtaxing the switches. Incidentally, I also ran into the exact same problem with that Netgear switch. I changed it out with a comparable Ubiquiti switch and the problem vanished. I have a Ubiquiti DMPro and a Ubquiti aggregator. Almost everything there is SFP+ to copper, though I do use a couple of SFP+ RJ45 adapters. By the way, though I'm pretty good with the stuff, I always learn something from your videos! Keep up the great work!
I have often used those, when setting up connections from a carrier to a data centre. With fibre, there are a variety of models, depending on the fibre connection. There can be single or double fibre versions, single or multimode and any of those with a variety of wavelengths (infrared "colour") to consider. Also, you showed a switch with several copper connectors and 2 SFP connections. When there are 2 or 4 connections, separated from the rest of the switch, they're generally used for upstream connections and will typically be faster than the rest of the switch. For example, years ago, I used to work with 24 port 100 Mb switches, that also had 2 Gb ports. Those Gb ports could be connected to a Gb switch, for large networks. The same holds with the speeds commonly found these days.
I’ve never seen an SFP for $10 or an SFP+ for $50 but that’s because we pay Cisco’s nonsense pricing where an SFP is almost $700 and an SFP+ is $1100 for single mode 10GBaseLR. Their QSFP28 units are $6000
"USB naming is weird"
SFP28 has entered the chat
I have a whole home network setup with a TrendNet 24-1GB and 4 SFP+ ports. I have one sfp port for my Pc at 2.5Gbps and 2 for my Synology DS1618+ duel 10Gbps (Aggregated) to equal 20Gbps. It works very well with the SFP+ and RJ45 adapters.
It auto switched to polish for me and I have to say, it's pretty amazing that you can do that now, but the constantly changing speed of the narrator is sometimes distracting. I feel like inserting a bit of a pause instead of slowing down the speech might be a good idea in some cases to make it "flow" better. There are some mistakes/things translated "too directly" where some context changes the word we would use in polish, but it's usabe. I still prefer to watch in english, but that was to be expected as I can hear the original in sync with the video and without any mistakes. Really nice!
In the Portuguese dubbing the RJ45 cable was dubbed to Rio de Janeiro 45.
KKKJJJKKKK
You say that folks haven't seen it before, but I bought an RJ45 to SFP+ transceiver recently with the expectation that no one else would buy the remaining stock by the time I wanted a second one, but no. Out of stock.
When I was in the military we had a connector that had about 120 pins in the connector and could transfer almost a terabyte of information in less than a minute however this requires a special setup to work properly and even then it's not particularly easy to use or get maximum speeds during transfer.
I worked at telco for 7 years, I'm very familiar with these😁
I have to plug in one of these SFP+ adapters for my modem's fiber internet connection. There is one 10 GbE port on my modem, which I can break out to other devices using a 10 GbE switch. I use a TP-Link TL-SX105 for this purpose.
I learned the hard way that not all DAC cables are compatible with every SFP capable device
Good video, thanks.
Super information to me. Thank you.
I've seen that on the back of my mom's AT&T modem. Had to plug it in when setting up her Internet. I wondered what that was!
My ISP modem has this to connect the fiber optic cable into it. It was back in 2020 when I got their newest modem I think, it was the first time I saw that thing, so yeah, I saw that thing before!
Oh, and it's pretty funny hearing French speeding up and slowing down suddenly, at least it works ^^
the portuguese dubbing of "RJ-45 connector" became "Conector Rio de Janeiro 45" 😅
I literally got to know these from the LMG vids.
For those who don't know, LMG Stands for Linus Media Group & it's the company headed by Linus Sebastian which has YT channels LTT(Linus Tech Tips), Techquickie, Short Circuit, etc.
Try switch off flow-control in that switch to solve the streaming fps issue
Last month I also added 10G to my Synology and pc. I use mellanox x3 cards from AliExpress with a qnap qsw-m408-2c switch which has 4 10G ports and 8 1G ports, of which 2x 10G combo ports. Next switch is a qnap qsw-1108-8t to living room and router which is 2.5Gbit.
There's a saying when it comes to lasers and fiber optics: Don't look at the beam with the remaining eye!
Both DACs and optical transceivers have some sort of PROM in them. Some brand of networking hardware care about what's flashed on them, some don't.
I actually do own a Cisco 24-port switch with an SFP port, I have no way to use it but I do have it.
The problem might be with your 10g pc connection to the switch and then onto the Apple TV.
You might be running into issues with the larger data frames and packet sizes in 10gb.
On the pc you could match the transmit and receive buffer to that of a 1g connection. I have run into this problem before with NDI
I use the SFP and SFP+ modules to connect my NAS and PC to the switch and my gateway/router to the ISP.
2:24 when’s the last time you wore a hard hat in a datacenter
I accidentally pulled one of these out of the back of my new AT&T fiber modem the other day, I wondered what it was! 😅 Lol, thanks for the info, Joe!
Note: they work much better when plugged in, hehe 😉
Literally every tech channel: You've never seen this network adapter
Is there a way to turn the automatic change to the voicetrack off or so I need to change my youtube language to english? Because it is already starting to annoy me...
I usually see this in Linus Tech Tips.
I was researching my laptop parts and this part showed up in some ads.
Have these in my home network. Most Unifi switches have at least two of them.
He looked into the cable and he saw the entire internet. All at once.
