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.

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.

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.
@ScrubRadius Жыл бұрын
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.

Seems to me that the SFF module concept was created not because it actually solved a problem that could not be solved at a lower cost (like having fiber ports built into the switch). But was instead created as a way to charge more for a base switch (to include the SFP interface circuitry) and even more for each module (and have to be periodically replaced); thus doubling the total cost of ownership and profits for something that should rightfully be a much lower cost.

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.

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!

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 had recently picked up the TP-Link adapter in your video but hadn't gotten around to install it in my UDM Pro. When you said it was incompatible, it had me concerned and I initially had some difficulty getting it to work. But, I found it does if I set the #10 SPF+ port as a LAN port. I really want it to work as a WAN so that I can use my phone as a backup Internet connection.

I've seen this connector widely used in telecommunication field. It's used to transfer data between the BBU (base band unit, function like the motherboard in PCs) and the RF module (radio frequency ); Which is connected to the sector antenna.

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.

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

Good stuff. I use fiber SFP, SFP+ and DAC and some RJ45 transceivers for 10G. Still, I learned some stuff today. Thanks.

Useful info, my use case is an old enterprise switch. I was originally going to use transceivers, but think I'm going to get expansion cards for the two systems getting 10 gigabit connections.

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"

When we upgraded our core environment. Everything went fiber to the distribution switches. But I had to dig up some of these as i need copper ports at our cores for certain devices.

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.

We have a few of these in a few businesses we look after as you said it tends to be SFP from Switch to switch put we also have teamed SFP into host servers to run a 20gbps uplink to those.

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.

I came across this (SFP) in some specs for switches, but never actually saw or used one. Seemed to be an common adapter to go to whatever type of media you actually wanted to use fibre/copper etc. I figured neat, but had no need to use.

I use two of them with my home network setup as my main switch is SFP+ but the server next to it is Dual 10G Ethernet and other rooms are fibered up.

Hi, good video. Also the german translation generated is very odd. I switcht to english since if was that bad. Also some comments / facts that are WRONG 3:43: This sfp copper cable are called DAC or Twinax. There are active and passiv once. Usuably they are only sold up to 10m length. 4:50: VERY WRONG!! each sfp (whether it is optical, DAC or converter to RJ45) have vendor bit set. If the NIC or the switch accepts modules with different vendor bits is up to the firmware. On some switches you can enable different vendor sfp but it sets a marker and when you have trouble they will not support you if different vendor modules are installed. 5:26 DAC calbe or sfp copper cable as you call them ARE even more sensitive to vendor bit and active / passiv mode. You have a cable and maybe need the sfp module on one end have another vendor bit set then the other module on the cable. If you don't like to pay the overpriced version of the vendor there are sellers like FS other other where you get quality modules coded to you vendor. Also if you need big batch there are devices to "copy" the vendor bit. But it is VERY important to get quality modules. At last I will point out that with 40gbit and 100gbit there are cables called break out which can split 40g to 4x10g and 100g to 4x25g. But make shure you switch support the port split sice the cable only is not enougth to split the port up. Also since you do not point it out, optical cable modules have also a release clip. And since you showed it in the video there are modules with one fiber port and some with two fiber ports. The two are called duplex and the one with one are simplex. Make shure to order the right optical cable. Also in optical there are sinple mode and multi mode which can not be mixed on the sides! Also there are single mode and multi mode cable. On the FS Website there is cmmunity and blog with MUCH inforamation about fiber and the other type. Please see there for a mode detail view in this high complex field bevor you order the wrong parts.

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.

I have worked with networks for years. The issues he has with the Netgear handling 10gb to 1gb can be attributed to many things. Could simply be a firmware issue. If not, it maybe the hardware design. Meaning that it depends on the SOC, on board memory, chipset compatibility, or other issues. Net gear has always been popular in the retail market. They do make some corporate grade equipment. I have used net gear switches for small remote locations. I don't think they make the best enterprise type of equipment. That would have to go to Cisco or other enterprise level switches. Even with Cisco, I have seen some connectivity issues. Usually the firmware on the main switch and/or the firmware for add on hardware like and sfp. Most lower end switches are made cheap as possible. So they do not have the best SOC, RAM, cache memory, and other hardware configurations. So it is always best to analyze the situation and your need. Do research. Plan for any future growth, needs, and scalability. Then go from there. Always pay close attention to the specs of the equipment.
