HSC-PH3-B2(68) — HSC Simplex Plug for 3.0mm Cable
The Hirose HSC-PH3-(68) is a simplex fiber optic plug from the HSC series, designed for field termination or factory assembly onto 3.0mm jacketed cable. It uses an Advanced PC Polished ferrule end-face for low back-reflection in single-mode or multimode links, and includes an integral strain relief boot (purple boot color) to protect the fiber at the cable exit. The free-hanging (in-line) mounting style mates with HSC adapters or receptacles using HSC ferrules. UL94 V-0 rated housing and a -25°C to 70°C operating range suit it for indoor equipment, patch panels, and controlled-environment optical networks.

Cable Fit and Fiber Compatibility
The plug accepts a 3.0mm cable jacket diameter — that is the outer cable dimension, not the fiber itself. It works with both 9.5µm/50µm core fibers (125µm cladding), covering standard single-mode and multimode glass fibers. The strain relief grips the cable jacket, not the bare fiber, so the cable construction must include a 3.0mm jacket to fit the boot and internal clamping. If your cable has a different jacket diameter, this plug will not seal or strain-relieve correctly.
