The Hirose HSCF-2A(P)(51) is a duplex SC-to-SC fiber optic coupler from the HSC series, designed to align two SC connectors back-to-back in a panel-mount opening. It converts from an SC receptacle on one side to an SC receptacle on the other — a straight-through adapter, not a hybrid or mode converter. A dust cap is included to protect the ferrule alignment sleeves when the ports are unmated.
Mounting and installation
This coupler mounts to a panel cutout using both a flange and snap-in clips — no separate hardware required. The dual retention method means it seats firmly in a rectangular panel opening and stays put during cable plugging and unplugging.
Hirose has placed the HSCF-2A(P)(51) in Last Buy status. That means the factory has announced a final production window, after which this order code will no longer be manufactured. No official direct replacement order code is listed in the lifecycle record. If you are planning a new design, check whether a current-production SC duplex coupler from Hirose or another manufacturer fits the panel cutout and fiber alignment requirements.
