QSFPNESE 1000BASE-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

I slapped this GBIC into my Juniper SRX300 firewall and it worked out of the gate. I was able to get an actual 1Gb throughput when testing file transfers across the SFP.

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. Im pleased with the adapter. It was very reasonably priced and is working well.
