The Hirose HSC-A3-D1(02) is a simplex fibre optic coupler from the HSC series, designed to join two SC-terminated fibre cables in a straight-through, panel-mount configuration. It converts from an SC Receptacle on both ends, meaning it accepts a standard SC connector on each side to pass the optical signal through a bulkhead or enclosure wall. A dust cap is included to protect the ferrule when the port is unmated. Mounting is via a panel mount with a flange and snap-in feature, which secures the coupler into a rectangular cutout without additional hardware.
Last Buy: Plan Your Final Order
The HSC-A3-D1(02) is in a Last Buy lifecycle status. This means Hirose has announced end-of-life for this order code, and the remaining available stock represents the final opportunity to procure this specific coupler. There is no official successor listed in the lifecycle record.
This coupler accepts any standard SC connector on both ports. The SC interface is non-angled (PC or UPC polish), so it is compatible with the vast majority of SC-patched single-mode and multimode cables. The simplex design handles one fibre per coupler. Installation is a panel-mount snap-in: prepare a rectangular cutout per the HSC series drawing, push the coupler through from the front until the flange seats, and the snap-in latches hold it in place. The dust cap protects the unmated port from dust and debris during installation or when a cable is disconnected.
