#DAC #Fiber #10gbe #10GB - วิทยาศาสตร์และเทคโนโลยี
The test on SFP+ connected in one end into an SFP port, is what I needed! Great channel. Thanks a lot!
Nice video! Thanks for sharing. I am very close to purchasing my first 10G switch (MikroTik) and first SFP+ transceivers!
Another good supplier of SFP/SFP+, fiber, DAC etc is Hummingbird Networks. I have tried FS store, Amazon, and Hummingbird. I like Hummingbird because of their great support. You call them to determine if their products are guaranteed to work for a given switch and you get a firm answer. If they don't know they will sometimes send you a trial device. If it works, you pay for it and keep it. If it doesn't work you simply return it. Can't ask for more.
Wow, I literally was looking at RJ45 SFP+ adaptors today. I didn't know if they existed, just googled to see if they do, and found similar amazon products, then this video. Perfect!
Watching from Iran. Very informative.
Thank you. \m/
I've been using 10GTEK for years now and LOVE it... amazing price and QUALITY product!!! Works without any issues, never had a failure.
Excellent Knowledge from your Video~~~Like it~~
Nice video! Thanks for sharing.
I run 2.5G Base T from my main rig over CAT 6 to a Mikrotik branded 10G transceiver on a CRS305, no problem negotiating at 2500 and I've gotten very close to that in sustained transfer to or from my NAS.
Thank for helping not make bad decisions
This goes back about 10 years, but the last time I talked to anyone at Fiberdyne, they said they had a new user applied, glued connector for certain types of fiber. The person I was speaking to said that losses were nearly the same as a fusion splice. I haven't needed more fiber for my small system, so never looked into it. And their prices for custom length bundles terminated to customer specs. were so cheap that it generally isn't worth looking into those connectors. 10 years ago the 6 pairs I bought were about $150 for about 130 feet, might have had a nonprofit/educational discount applied.
When I want to sleep I go to this kind of video, quite a relaxing video and I’m learning as I sleep ;-) I’m a network guide needs to sleep.
I dream in cables ;)
We've been using 10Gtek transceivers for both ubiquiti and HP procurve / Aruba switches for 2-3 years. Haven't had a failure yet.
Wich 10 GbE cards or onboards chipsets (i.e. Aquantia AQC 107S) do you use?
i'm just starting to upgrade my home network to 10g and got one of those mikrotik switches coming! i'm trying to use the direct attach cables when i can to reduce heat but will need at least a few of the rj45 modules. i actually already have cat7 and cat8 cables because they were cheap and i didn't need very many, but this is a pretty old vid haha
Run iperf if you want to get a great idea what your network speeds are. Perfect for fine tuning especially with pfsense but higher throughput is best with TNSR.
I'm working in a Datacenter as engineer and if a costumer asks for MMF connects I just show him the door or hit him with my SMF/E2000/APC whip.
TLDR: Use Singemode
Rant about MMF:
From an investment standpoint, if you still have OM1 (gray) cableing, rip it out. If you have OM2 (orange) or OM3 (blue) ok.
Don't buy OM4 for new long runs over 30m, it's ok inside a rack but it's failing to often.
Don't be hyped about OM5 - to expensive and in 850nm it have more lost than OM3/4 because it's made for WDM SFP's with multible colored waves in one fiber.
For new installs, use SMF and splice them to an APC Connector LC/SC or best E2000. Yes you need matching patch cabels for it, but if you forward a fiber link from your carrier through a building to your office via multible patchrooms, you will see the difference. Yes the SFP's are more expensive (20€ vs. 26€ @fs) but in the future if you upgrade to 25/100 or 400G. 400G QSFP-DD LC Duplex with 10km LR4/LR8 are on sale now (4000€-10000€ per SFP but 400G!!!)
Even if you only need 100G at the moment or even only 10G, you don't want to replace you pre installed cabeling only the SFP's. (100G is @ 1400€ for a pair of SMF QSFP28 Modules)
Also most QSFP-DD are SMF only.
I normaly compare vendore SFP's with FS or flexoptix pricing and then choose what I need. If I need max. compatibility because I sell them to carriers if they have a broken one and need a replacement now - I choose flexoptix flash them and it works.
If you build a office, just run fiber most of the way, pace a switch where your users are or plan floor tanks with space for switch, patchpanel, cable etc.
Yes a fusionsplicer starts at 2500€ and easily go up to 10000€ but when I had the first one with a raw 12core cable on hand I had figured it out in ~30min without introduction. Also the device tells you if the spice is ok, @ rj-45 you mostly have to check the complete cable to find the error.
an idea for your next project. rgb lan cables and if you can control the lights in them you get even more kudos for doing that
The MikroTik S+RJ10 SFP+ module will do 10M/100M/1G/2.5G/5G/10G, but I don't know if they'll work in a Ubiquiti switch.
(Traditionally) branded equipment (Cisco, HPE, ...) is more "picky" about modules you can install into them and accepted modules can be much more expensive as well.
Great video!

NOS cisco 10 g adapters under $15 on ebay used hundreds of them
Thank you!
It's sad, because especially with regards to professional WiFi 6 APs or newer mainboards, 2.5GBase-T will certainly establish itself as a cheap step in between. What is really missing is an all-round switch that can handle 1G, 2.5G, 5G, 10G over copper AND/OR fiber.
MikroTik has copper SFP+ modules "S+RJ10" that support speeds from 10 Mbps to 10 Gbps including 2.5 and 5 Gbps.
Or if you want a switch with copper 1/2.5/5/10G ports - have a look at MikroTik CRS312-4C+8XG-RM
I've recently bought the Netgear MS510TX which seemed like a nice solution.
thx, havent noticed that Netgear yet. Looks nice! How noisy is the fan?
The MikroTik Switch would be fanless, but SFP+ Copper Modules are surprisingly very expensive...
Netgear MS510TX
The 10G fiber to copper module usually has higher power consumption than the SFP+ standard 1.5W, probably around ~2.5W. This causes the heat and thermal problem and makes it more than 70C. Unless we have a good "cooling" system in the switch. Did you agree with that?
I do not see links to the 10G card
Can you show wall plates for fiber cat7 cat8
Were was this a few days ago? while I figured out sfp+ trancevers and fiber
I'm working as fast as I can! ;)
@@LAWRENCESYSTEMS LoL, just had to figured out type of fiber, fiber connectors and matching transceiver transmission wavelengths the ones I ended up with were 850nn
Now those 10gbps SFP+ cards are like 15-25 on ebay... I aggragate to 20Gbps on my servers.
If I have to rewire the house I'd go for the highest available standard, CAT8 or go glasfiber. With the latter being costly but also interference free when new wireless signals might end up trying to interfere with the copper cables again in your house.
25GBASE-T and 40GBASE-T were standardised 6 years ago and yet I can find no evidence of them being included in any actual products (thoug I do see a bunch of SfP28 products mislabelled as 25Gbase-t). I would not bet on them ever doing so. It's also worth noting that when 10GBASE-T initially showed up it was only available as a fixed port due to power issues, SFP+ 10GBASE-T transceivers came later and were/are limited to only 30m rather than the normal 100m.
If you think you may at some point need more than 10 gigabits per second then IMO your most sensible options are either to run single mode fiber or to run ducts/conduits into which future cables can be pulled. Multi-mode fiber is also an option for short runs but is less future proof.
fiber isn't expensive
Can not run Cat 6 in same conduit as Electrical So,I want to run 100' Fiber ( OM3 duplex 50/150 OFNP LC-LC ). Reason Fiber is... it will be in with 120v electrical wires in the same conduit from house to my garage. Will this work ??
Note: Not all PCIe cards with two SFP+ slots can do dual 10Gbit. Some can only do "failover"; eg. 10Gbit on one port and if that fails, you get 10Gbit on the other instead.
I prefer fiber everywhere I can, because once you've tried frying a few 8P8C ports (due to high voltage differences between devices), and you no longer can upgrade your Mac OS, you're not going to risk doing that again.
(Well, it wasn't only the two ports on the Mac Pro's motherboard that got fried; also my router and my switch - the switch can now do 100Mbit instead of Gbit, so it still "works").
In an enterprise environment like a data center it’s better to use lc lc cables than dac even sfp+ is better. The optics get really hot in a data center environment and the optics fail. Dac cables if this happens the entire cable needs to be replaced. With lc the optics just needs replacing. I have never had a cable failure before it’s always been the optics or a port failure. It’s a pain because if the dac cable is 20m and the optics fail you have to pull the entire cable out and replace it which in a data center is a time consuming process.
which small 10g switch it is ??
there are alsow sfp vdsl modems (vdsl modem in sfp form). great for some stuff.
mind giving link? I'm thinking to do some DIY routers but the problem is the VDSL part. There is one PCIe based thats too expensive and if I even try to google for standalone VDSL box/module/card, everything points to built-in VDSL+router combo that tends to cheap on the router chipset and also coarse control over VDSL part

@@haziqsembilanlima there are vdsl sfp clients (for connecting to your isp) and lan extender (two modules, one master and one slave)
Almost 100.000 subs :^)
SO the SFP+ cable can also be used to connect to a disk array? OR is it a different type of cable?
SFP+ is a network form factor, not disk.
Your server room is hotter than the port!? 😂
Whats the actual intel nic model though
now I just want 10 gb network. Do you have links to all that I would need to start?
That very much depends on your needs and is a good topic to discuss in my forums forums.lawrencesystems.com/
Is LC multimode cable the choice for home users if you want 10Gb fiber connection?
Yes, unless you go with copper of course, both are capable with the correct cable/distance
The heat issue with the 10g sfp+ modules is really when you have 2 or 4 of them right next to each other and they heat soak each other. Most switches tell you to skip a slot when using them. Would be nice to see what 4 of them next to each other does.
I have many 48 port 1U Arista switches full of 10GbE SPFs and no issues
Thats really a issue if u are using the ethernet rj5 to SFP+ adapter.
any recommended switch hub that has atleast 2 ports of 10G RJ45?
All I can find now are all 10G SFP+ switch hub but my LAN & NAS only has 10G RJ45.
ASUS has a switch with 2x 10Gbit RJ45, the XG-U2008. No personal experience with it, though.
Unifi have a 4 port rj45, and 12 sap+ all 10g, Managed, Ana support link aggregation They’re not silent though, but are great.
i like it
Good evening I have a question I have a Dream machine Pro from ubiquiti and a 24-port switch The US-24 from ubiquiti what kind of cable do I have to buy to connect these two together I would like to connect these over sfp ? I wonder this because the Dream Machine Pro has 2sfp plus ports and the Switch has two regular sfp ports
DAC SFP
@@LAWRENCESYSTEMS thanks for responding so quickly I will definitely buy this
@@LAWRENCESYSTEMS I have another question I have searched around for DAC cables, but they only sell SFP Plus of this variant, do I have to adjust a setting in my router to use an SFP plus DAC cable in my 1 gigabit Switch?
So with this i can hook up with a 10gbit direct connect to Amazon Web Services?
if you have 10g internet connection and AWS supports it, yes.
Thanks a lot. Help me please. I have cat 6a cable and buy sfp+ rj45.. why only 30m... i have 70 m... what can i do to 10 gbps? Thanks for your videos
If you want 10 Gbps over 70m into a SFP+ port, sounds like you need fiber.
@@danbrown586 he needs a rj45 10g switch
will 1g rj45 receiver in between 10g network card and 10g NAS will only run 1g?
yes only 1g
Out of experience: the RJ45 modules always hotter than the fiber ones. I don't really understand it because only in the fiber modules there is a conversion and the amps going through the copper line should be fairly low. It is how it is
There most certainly is a conersion in the 10GBASE-T modules, between the simple serial data stream used by SFP+ and the complex modulation scheme needed to get 10 gigabits per second down a long cheap cable. Power requirements are the reason 10GBASE-T SFPs took a long time to hit the market and when they did so they were limited to 30m rather than the 100m of regular 10GBASE-T.
Can the blogger help me amazon review it?
Im using om4
12:14. Cat6e. Well that’s a new one lol.
oops ¯\_(ツ)_/¯
What makes a 10km SFP a 10km, and a 40km a 40km? What is the difference? Is it power tx power and receive sensitivity?
Don't use the 40km transceivers when it's absolutely necessary. The 40km and 80km transceivers have way stronger laser diodes and if the link is too short, the light received on the other end will be too strong to recognize any signal. These kind of transceivers are used for very long fiber runs (e.g. fiber running between two distinct datacenters) which is considered an engineered link.
Has anyone used a HPE sfp+ module on a mikrotik switch? I've a few of them laying around and I'm thinking about buying the css326 24g 2s+ switch for my soho network.
It should work as MikroTik is not overly picky,
I have about 100 feet I want to run a 10 gig back bone from my office out side to my home. Can you get 100 feet of fiber already made up. or will copper be better. Every thing in the office I want all 10 gig back bone. That way every thing will be fast as I can get it with in the home network, for security cameras and the such.
I know you can get 30 meter fc pretty easily. I want to say I've seen 50 meter out there but it's been a while. Distance for fc really depends on the transceiver power.
Fiber is necessary for anything outside unless you want a thunderstorm to wipe out your entire home network and every device connected to it. Here's a 30 meter (98 foot) fiber cable: www.amazon.com/Meter-Multimode-Duplex-Fiber-Optic/dp/B006KSS26A/
Finally someone who knows how to pronounce "MicroTik". =)
-To my knowledge, there's no firmware on the SFP / SFP+ modules; there's only a short byte-table of 16 bytes (if I remember correctly).Those tables can easily be duplicated by a manufacturer, but if you purchase one that is 'coded', then it will only work in those products that are compatible with "anything" and those that require this code-table (like CISCO).
So a CISCO-compatible module would (likely) not be compatible with HP and vice versa.
That said, there are some modules, that contain diagnostic support, which means they'd have a microcontroller built-in, which means ... they would have firmware. Fortunately for us users, the diagnostic support is optional, so we are not restricted by that.
Hi where are the links to the items?
Here you go kit.co/lawrencesystems/network-gear
Which sfp standard can go 25/40/100Gb?
25 is SFP28. 40 is QSFP+. 100 is QSFP28.
Anyone have reccomendations for aruba switch compatibility?
Aruba does not accept random ones. You need Aruba coded or original Aruba parts.
But you can always try the "accept 3rd party transievers" (you have to google for whatever the correct syntax is for that functionality) option first.
why just use LC fiber lach conected direct to red adapter? why use the SFP+? its not more easy conect optic in the red card and the card make the swich from optic to electric signal?
#Designer#sub#Highlights#episode episode Full#awesome
For 30m(~100ft) connection for 10G, do You suggest copper or fiber?
Fiber.
For me it has been the fiber route, but 30m is copper territory. After 100m it is all fiber.
Fiber

FYI "meecroteek" is correct according to their forum post:

Why SFP or SFP+ connectors are so expensive.? 😰
Because all the conversion is done on the connectors, unlike RJ45 where the conversion is done in the switch or NIC.
Tom, you make me nervous when you keep leaving fiber connectors uncovered. The dust caps should go on as soon as you disconnect.
Remember the conductor on OM3 cable is only 50um diameter, OS2 cable (singlemode, what I usually deal with) conductor is 9um wide....A human hair is 60um in diameter, so it doesn't take much of a dust particle to block or severely attenuate a fiber connections.....If you're going to be handling them like that, get the right sized cleaning pens to clean both sides of the connection before reattaching them

@@LAWRENCESYSTEMS You won't see any difference, maybe latency measured in microseconds depending on how hard/much DSP is in and SFP/SFP+ to adapt the electrical lanes on the SFP/SFP+ to whatever media you have. Or you have packet loss because your physical layer is introducing bit errors. You don't need iperf to tell you that, the network interface stats should tell you when that's happening.

It is pronounced "meecroteek" this comes from the Latvian language (MikroTik is from Latvia, and in Latvia they have our own unique language). The name comes from "Mikrotīkls" which means "Small network". It was shortened for easier spelling internationally.
