Great product, show up as part "SFP-10G-T". Plug&play in mikrotik got 10G over 20-30Meters against a AQC107 NIC.
I ordered a module marked "Cisco". In the SFP 1Gbit slot of the Cisco SG200 / SG300 / SG500 network switch, I only see the link in a fraction of a second and no more links, it doesn't matter if Speed and Duplex is Automatic or manual. The link to the master end only appears in 10G mode in SFP + sockets with Mikrotik routers and network switches, unfortunately the quality of data exchange could not be tested. The Intel X520 network card works, but only 10GBit, does not work 1GBit, the D-Link network switch only works Transmit and does not show the link, the other side shows the link, but there is no data exchange. Does not work in various Mikrotik 1GBit SFP slots. Unfortunately, I was hoping to get more universal than this. Cisco dropped out of the selection at all, although there are the most. I can't test Cisco SFP + right away, maybe I can in the spring.
