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 have a Cisco 3850 and older switches to use this transceiver on. All of my devices worked just fine with this and didnt need to force compatibility in the config. It just worked out of the box and didnt exhibit any issues from my testing. Worked fine for uplinks and testing on the equipment I needed to work on.

Speeds tests with this and with a normal switchport were very close. Metal well-made lever to remove the module, standard packaging for SFPs. Works in Cisco or at least if you enable non-Cisco SFP which is typical for my applications. If this unit does not work in Cisco it may be errdisable, fix this use no err-disable detect cause gbic-invalid, and service unsupported transceiver. If disabled then shut down and re-enable that interface.
