My network upgrade and you need these transceivers to connect with RJ45 from a system with 10G RJ45 jack or to flexibly long RJ45 cable (category 7 or 8 ) another SFP+ device and use the transceiver there. It worked great and was so cheap compared to other SFP+/RJ45 transceivers that I ordered 5 more.
