You've got an STR connector on the fibre side and need a clean copper-to-fibre bridge without hunting for a match at the big-box store. This Alloy FCR200STR converts 10/100Base-TX to 100Base-FX multimode fibre over up to 2km, with Link Fault Passthrough via Forced or Far-end Fault mode so a dead link upstream doesn't leave you guessing where the break is
