I can recommend the LHY FMC. Reasonably priced and does a great job. You can get excellent Fiber optic cable and SFP modules from Finisar. They are industry standard and great pricing. I run my setup into a hifi rose rs130 it has fibre module capabilities. Very clean. All told the Ethernet cable, Fibre cable the 2 Sfp modules and LHY FMC was around 600 bucks
Cheap way to give it a go
