XZSNET 1000BASE-T SFP Transceiver, SFP to RJ45, 1.25G Copper SFP to Ethernet Module Compatible for Cisco GLC-T/SFP-GE-T, Ubiquiti UniFi UF-RJ45-1G, Mikrotik, Meraki, Netgear, D-Link and More, 1 Pack

worked perfectly with my Yuanley 2.5GbE ethernet switch.

Purchased for my 2.5 Gbit hub that has 2 SFP ports, Only needed a 1Gbit port (to connect my 2.5gbit hub to a 1gibt switch) so it saved me wasting a 2.5gbit port..Paid £7.99 for this at the time of purchase (Amazon Warehouse Deal)Works as expected.. speed is as per 1gbit connectionPros• Cheap• Works WellCons.• 1GbitCant think of much else to say on this ...Would buy again...

Bought a pair of 1000Base-T to be able to utilise the 2 SFP ports on my TP-Link SG2210P. They went in and I plugged in some devices and all seemed okay. I did notice they appeared to have an odd blinking light pattern (rapid flickering as normal followed by 2 seconds of off) but didn't think anything of it.I then noticed that in Omada the port would occasionally claim nothing was connected which upped the odd but I ignored that and since the devices using those ports weren't critical and appeared to be working.Then I rewired and plugged in a desktop to one of them. That's when I found they were essentially resetting every 10 seconds or so. I'd get 100% packet loss and then back to normal.They are either not compatible with this switch or are duds - either way I have returned them.

Performing well - the price seems very reasonable so I wasn't sure what quality to expect, but it's good. No issues. Would buy more of this brand when required.

Works as expected

Not sure if it was to do with the switches I used or the devices but I was getting dropped packets when using these devices. I tried connecting VIMIN 2.5GbE switches to an Omada ER605 gateway and it dropped packets badly. I tried it directly between the VIMIN switches and it was the same. I've since fitted into a LIANGUO 5 Port 2.5GbE and that works OK, but I've not yet really load tested it properly.Swapped to a full fibre link for the VIMIN and it worked relly well and stopped the dropped frames.

As per other reviews, the connection constantly drops/flaps, if you unplug it, try again, it may remain stable for a little while but it'll happen again. I was using it with a Unifi USW 24 port PoE switch, sent it back though as it's too unstable.

Bought from Warehouse - discovered that my device (NAS) was getting disconnected every few seconds and reconnecting. Maybe my fault for buying used - be sure to buy new. Will replace with a new one and see if any better. Sometimes you get what you pay for!
