In this video we explore the Gigabit Passive Ethernet Repeater (GPeR) and its purpose along with the IP68 rated outdoor case. mikrotik.com/p... mikrotik.com/p...
The IP68 case seems good for more than just the GPeR itself. It seems like a great solution for protecting connectors in the field where a midline join is required (e.g. a Keystone to Fly-lead connection)
@@nagi603 Not as unique as you may think. I have like 20 of these cute little poe++ in 5 port din rail Chinese switches, you can even cascade them just like this they are like $12 on aliexpress and they work well. And there are poe powered ethernet extender devices like this, ones that even advertise as being suitable for direct burry, idk if those ones do cascading though perhaps you only get one hop out of it.
TiBit had some really cute SFP+ XGS-PON / EPON OLT in a standard SFP+ module. Not just a transceiver but the full on OLT in the module. Only did 10km at 128 split but still it could turn any SFP+ port into an OLT. We were close to buying a bunch but ended up going with 60km gear from calix instead. They seem sold out everywhere now. It was custom ASIC so IDK if they ran out and or what. The paring ONT in SFP+ form factor is common these days.
I can see them being useful in a way like Extending PoE security camers like when we go past 100 m these will be really helpful I don't think these will be replaced for fiber Noone should use these for fiber because I think the latency going off the roof These are just like wifi repeaters works for some connections but they are not know for their great latency experience
These already existed from others, but your price is better and I trust your brand more. V2 will include a voltage booster for unlimited distance when powered from POE++++++++. Also people asking about latency, won't be an issue for anything normal, only stuff like PTP would possibly be troublesome.
@MikroTik Please make the mythical ethernet y adapter. Like I know they existed in the 10baseT day with a passive diode based hub but do one with poe but make it small enough so people scratch their heads, like the usb to serial adapters with all the electronics in the regular sized housing.
Extending copper Ethernet this far usually is a bad idea, and a good reason large network deployments use fiber is for galvanic isolation. Not just because increasing the length of cable means you have more chances of electrical noise ingress, but lightning and even inter-building line voltage and ground potential differences are a concern. Many environments where someone might be tempted to use these would end up being the worst possible places to use them. Manufacturing facilities are one such example where multiple sources and types of incoming line power and diverse grounding conditions exist and copper networking is best to be avoided. Fiber is used to link buildings in corporate and educational campuses, again because of electrical concerns. It may make some sense to use these for PoE IP security cameras, but typically locations where it would make the most sense (parking lot lamp post mounted cameras) are handled by wireless transmission and powered directly from the lighting circuit prior to any daylight sensors to avoid burying additional cables.
Have you watched the video? This is not some passive extender, it is a powered switch with two ports. There are no risks in this case, just like using any other network switch to connect networks.
@@GrizzLeeAdams The data is isolated in little tiny transformers built into the ethernet sockets (actual physical ones not um other kinds of ethernet sockets). This works because it uses Differential signaling and algorithms that encode data in a way that unacceptably long strings of sequential 0's and 1's are never sent down the line. So data on an ethernet line is galvanically isolated on each end of an ethernet interface. I have not disassembled one but if you read the spec sheet you will see a voltage drop between units that far far exceed what you would see from resistance losses if the voltage was just being passed along. They are clearly isolating the voltage from one link to another. They have made a good product, and you thinking you know some small bit on the topic are on TH-cam talking out your sphincter.
How smart are these things? Is there a switch chip? Do they digest ethernet frames or will they relay pretty much whatever signal they get on differential pairs, for example AES50?
How much POE power can this pass? If I feed this with a POE++ class 4 source (90 watts), will it pass 60 watts to the end point? I'm thinking a single extension to a PTZ camera rated for POE++ 60 watts, but my switches can supply up to 90 watts per port.
The primary use of this device is Ethernet range extension. While it could power a small device, it only supports passive PoE and the maximum current output is 0.7A.
If the emitted signals are good enough then GPeR will be able to pick them up after 210 meters of cable, but it is recommended to do lower distances than that as many factors come into play.
Some devices are built with out the consideration of geting power injected through the ethernet port. Depending on the design of the device, it could be demaged or destroyed. As 24v passive poe does not require a handshake, but is "always on" you usually need to manually enable/disable it in a switches management interface, or in this case, via jumpers. hope this helped
@@egomatthisum passive Poe switches are pretty much a thing of the past unless it’s built specifically for some industrial applications, or some specific application. Most network switches follow 802.3af/at standards, voltage out is auto negotiated and shutdown if not required. Looks like Mikrotik has switches with passive Poe In/Out option (aka Poe injector), but those don’t come with power supplies and designed for someone who knows what they are doing

please don't tell anyone about these. We use these all the time
Love the TV at the end.

Yeah, but there were already existing solutions for those from other manufacturers. The GPeR seems more unique.

Best MikroTik device who works without Router/Switch/OS xD
I am hoping and praying that you guys come with a OLT as soon as possible. I know that will be the next big product in the mikrotik link off products

They work wonderfully with any of our WISP radios, including Tarana even.
Nice outro ;) Where did you find the audio for that please MikroTik?
😂I thought I noticed it alone . Cool way to end it though
Here you go :)

@@mikrotik I understand it is an active extender. Again, galvanic isolation is a serious concern when you're reaching the limits of copper ethernet.

where to buy? not available on amazon.

What is with Ethernet latency ? Will it not to long for a normal Ethernet timeout (arp and so on)
So cool
Nice!
can mikrotik gper use for this setup?
48v gigabit poe switch -->> 75meters cable-->> mikrotik gper-->>75meters cable-->>access point
It depends on many factors, but it could be done.
omg thats so cool
these are no replacement for fiber!
Never use ethernet between buildings, allways use fiber!!
Does this cable still pass NetAlly/Fluke cable test?
How smart are these things? Is there a switch chip? Do they digest ethernet frames or will they relay pretty much whatever signal they get on differential pairs, for example AES50?
Yes, there is a switch chip. It's basically a PoE powered two port switch.
@@mikrotik Thanks for the info

@@mikrotik thanks. I may still need to grab some of these and power the camera locally.
or just use a fiber!
Fiber is cheaper than copper now.
The power to go along with it is what costs.
PoE over Fiber is now a thing??
@@mikrotik if you have to push some power to +1km away location and you want to use an Ethernet cable, you are thinking it wrong.
@@bucharestcartraffic your arguments are destroyed only by existence of such thing as security cameras.
How can there be 210m between two GPeRs?
If the emitted signals are good enough then GPeR will be able to pick them up after 210 meters of cable, but it is recommended to do lower distances than that as many factors come into play.
IP68 GPeR? Now divers need a hand signal to indicate not only fish or directions, but also a GPeR.
How much?
29$
A bit expensive for a run of the mill PASSIVE PoE extender.
It's active - it's a PoE powered two port switch which also optionally injects power on one end.
Could you elaborate on why it is not a good idea to insert power where it’s not needed?
Some devices are built with out the consideration of geting power injected through the ethernet port. Depending on the design of the device, it could be demaged or destroyed. As 24v passive poe does not require a handshake, but is "always on" you usually need to manually enable/disable it in a switches management interface, or in this case, via jumpers.

use this in cctv. wery useful thing, when we need link in more than 200m
