The Hirose HSCF-2A-D(P) is a duplex SC-to-SC coupler from the HSC series, designed to align two SC connectors back-to-back in a panel-mount bulkhead. It accepts an SC connector on each end — the zirconia ferrule sleeves keep insertion loss low and repeatable across mating cycles. The blue housing and included dust cap are standard for this series; the duplex format means it handles two fibers per coupler, one per SC port.
Mounting and Environmental Limits
Mounts through a panel cutout using the flange and snap-in tabs — no hardware needed beyond the panel hole. The synthetic resin housing holds up in typical central-office humidity; the dust cap keeps the ferrule bores clean when a port is idle.
Hirose has marked the HSCF-2A-D(P) as Obsolete. For existing BOM lines, the options are a last-time buy through surplus channels or a qualification to a current-production SC duplex coupler from another manufacturer — pin-compatible panel cutouts and SC interface dimensions are standardized across the industry, but the exact housing color and dust cap design may differ.
