Your copper run hits 100 metres and dies. You need fibre. But you've got MT-RJ patch leads already terminated in the ceiling and no converter that fits them. The FCR200MT plugs into your existing RJ-45 switch port on one side, takes MT-RJ multimode fibre on the other, and pushes your link out to 2 kilometres. No config. No drivers. Slide it in standalone at a cabinet or drop it into a DCR12 chassis if you're running multiple conversions alongside it. Powered by plugpack or USB — whichever's handy at the rack. If your MT-RJ cabling is already in the wall, this is the piece that makes it work
