Review on HINYSENO Gigabit Ethernet Adapter 1000Mbps by Lucas Salgado

Connecting two of them directly gives me 118 MB/s TCP on unconfigured systems (the only thing I did was install mtu 9000), no firmware in Debian required, only fully transparent PNP .tested FS SFP and HiFiber SFP with no problems. This was bought to provide some lightning protection for very old systems (the system itself is isobaric protected but the incoming RJ45 comes from a switch that has other computers that are not protected so it was decided to use as many connections as possible to be replaced by optics for further protection of systems against lightning surges). the only problem is that they are outdated, as you know, when you connect usb3 M type a to usb2 type a, the connection is always imperfect, so it's a bit difficult. Otherwise the first impression is good.
