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

This worked immediately when I plugged it into my Mikrotik hEX S router, giving me an additional usable ethernet port. Checked the interface, and it was auto-negotiated at 1Gbps (max speed on the SFP port of the hEX S). Ran a speed test plugged into this adapter and compared it with plugging directly into one of the existing ethernet ports, and there was no noticeable difference. I have gigabit cable internet, and got a little over 800Mbps download speeds in both tests, which is expected for my setup considering everything else on the network at the time the test was performed.

This copper transceiver has very good construction and high-quality materials are used. It works exactly as its supposed to and provides excellent speeds. Other reviewers have given detailed information as to its performance. Amazon Vine sent this product to me for an honest unbiased review. Would I recommend it? Yes, if you have a need for a copper transceiver, then this is a good option for you.
