QSFPNESE1000BASE-T SFP RJ45 Copper Transceiver up to 100m Over Cat 5 Cable,Compatible with Cisco GLC-T/SFP-GE-T, Meraki, Mikrotik, Ubiquiti, Netgear,TP-Link and Other Open switches

As a person in the IT field, being able to plug into a switch in any available port is often a problem if all the standard rj45 jacks are in use. Enter this little transceiver. Lets me plug into any available SFP port on (any?) switch and begin troubleshooting. As long as the switch will recognize it, you're golden if you just need to pop in without unplugging something else (unless of course, all the SFP ports are also taken, but that's rare in my experience.Extremely handy, works perfectly.

This is a very good and high quality port. It is not compatible with Aruba switches. It comes up as an unsupported device on my Aruba switch. I gave it 4 out of 5 stars because it isn’t universal and doesn’t work with all brands of switches.

This SFP adapter seems well made, and, so far, has performed flawlessly providing a backbone network connection from an 8-port Gigabit POE switch.The POE switch this is connected to services eight video security cameras, a mix of 5MP and 4K cameras, all running two streams, (full-res and a sub-stream), at 15fps. This generates a steady stream of network traffic with little room for error. This SFP adapter handles the traffic with no issues, network packets are clean with no drop-outs of corrupt packets.The adapter is housed in a precision all metal case. It fit the SFP socket perfectly with no issues. The RJ45 socket has a locking flange to secure the connecting cable. This is a "plug-and-play" adapter - No setup is required.I'm pleased with the adapter. It was very reasonably priced and is working well.

I tested this on my Dream Machine Pro and had to set the port to 1000M because of a bug in the software, but this worked fine. Good option if you need an extra RJ45 port in a pinch.

Have a couple of Cisco N5K. Does not work at. Tried on Force-10 and worked fine.
