FYI,

Corning makes an integrated USB/fiber -> fiber/usb solution:

I have four fiber lines from the house to the garage/hamshack that replaced two ethernet lines. Each is 111. ft long.  Each line carries a grouping of connections such as one for my Flex system, one for my Electraft system, one for Broadcastify and data collection, and the fourth for ‘all other’.  I have my network in the shack segregated so that if the Flex system goes out the Elecraft system will hopefully continue. Given that I primarily operate remotely, redundancy in amateur operations is critical because it may be 4-6 weeks between visits to the ham shack that is over 1,280 miles away.
