XZSNET 1000BASE-LX SFP Transceiver, 1.25G SFP to LC Single Mode Fiber Module Compatible with Cisco GLC-LH-SMD, Ubiquiti UniFi UF-SM-1G, Mikrotik, Meraki, Netgear AGM732F, D-Link and More, 1 Pack

Works as expected and perfectly. Inexpensive module works with EdiMax Pro, Mokerlink and TRENDnet switches for certain.

I needed another copper port on a switch with the only open port being an SFP port. This worked fine in an Adtran switch so it should work in a Cisco switch or compatible as long as the switch OS is up to date. That's the only caveat. If you have an older switch it might not allow a copper port in an SFP slot, so best to check OS firmware for use.

I wanted to give this item ZERO stars, but the lowest option is a single star. I recently bought two Supermicro 2U servers with their "SIOM LAN Support". The SIOM card in these systems has two SFP+ ports. I bought these SFP+ RJ45 transceivers specifically for this application. Unfortunately I took me until now to figure out that what is at fault is these transceivers! I had a run of bad luck including an immaculately looking Xeon processor being dead. However, after trying unRAID, TrueNAS Scale and Windows 10 it is no apparent that these RJ45 transceivers are NOT compatible with Supermicro. Unfortunately by now more than a month has passed, so I am out out $160 and have four completely useless paper weights to show for it! Explicitly advertising these transceivers to be compatible with Supermicro is FALSE ADVERTISING. Given that fact, I would not trust any of the other claims regarding compatibility and could not recommend this product to anyone! You have been warned. Pay extra and get an Intel SFP+ transceiver - don't get suckered in by the cheap price, because if/when it doesn't work you're still going to have to buy the more expensive transceivers anyway!

A nice option for those who have SFP+ ports; connectivity, quality, fit and functionality are all good. No heat problems but you typically don't have them with 1Gbps ports, only the 10Gs have the propensity to run very hot so I didn't expect problems. All good.

Worked well for video streaming with a very affordable cost vs brand name one such as AJA SFP.

I bought these to make use of a pair of SFP ports on a Cisco switch and another on a YuLinca switch. They worked in both cases, were easy to install and recognized out of the box and worked well with no operational issue. I did not like how hot they get. They get hot to the touch, over 100F. I have never handled SFP's that get this hot. That being said, they have not failed and work as described. In my YuLinca switch, they are being used to connect two 2.5Gb/s Ethernet ports. Throughput tested correctly, the SFP handles the 2.5Gb with no added latency or packet drop. I remain concerned about the heat issue, as I expect that to affect their long-term reliability. I mean, if they get hot to the touch, imagine how much more hot they get inside. That being said, I still have them in service in my home and have not had negative issues with them. ***UPDATE, to 4 stars - excellent communication with the seller*** The seller kindly got back to me about my temperature observation. They explained that the module employs the Marvell AQR113C chip, which delivers more performance and stability but consumes slightly more power than common alternatives. It was also stated that high-quality thermal pads are applied both inside the module and around the chip to ensure effective heat dissipation. Plus they have a two-year warranty should issues arise.

Works great. Using with a Ubiquiti WAN switch. Plugged in and it worked right away.

Used on UDM-Pro-Max, no issues worked right away.
