Even though in the time, it seemed that we would deliver Turris OS 5.2 before New Year, it seems that we somehow failed. It was too ambitious, I’d say. New features do not belong to fixup releases.
It’s going to be part of Turris OS 5.2, right now, we are in the (internal) testing process before it reaches HBK and HBT.
It is supported by HW and SW currently. If you connect two Turris Omnia routers by using an SFP cable, it reaches approx. ~2.35 Gbps by using iperf3 and default MTU. This is a test, which was made one year ago.
About SFP modules, it is a little bit complicated because you need the other side, which communicates to you by using the correct mode (not 5 Gbps, not 10 Gbps, but 2.5 Gbps), some SFP modules required to change their EEPROM.
Why would you? I’m going all in! The surprise is coming, I know it! Just give us a little bit more time to release Turris OS 5.2.
Also, with SFP modules it is a little bit complicated, but we are working on it and bring fixes and improvements to the Linux kernel. Recently, we were working on some GPON modules.
