What This HRFC-P8-H2(63) Fiber Optic Plug Is
The Hirose HRFC-P8-H2(63) is a simplex fiber optic plug from the HRFC series, terminated with an Advanced PC Polished finish and an integrated strain relief. It mounts free-hanging (in-line) and accepts cable with a 2.0mm outer diameter. The blue boot identifies it visually on the harness. The fiber core diameter is specified for both 9.5µm and 50µm cores, with a 125µm cladding — covering single-mode and multimode fiber in the same plug body.
The HRFC-P8-H2(63) is on a Last Buy lifecycle status. This means the manufacturer has announced end-of-life and the part is available only through remaining stock or the final production run. No official replacement or equivalent order code is listed on record.
Key Fit Parameters for the Harness
The 2.0mm cable diameter is a hard fit requirement — the strain relief and boot are sized for that specific OD. The Advanced PC Polished finish on the ferrule end-face gives a low back-reflection termination, typical for single-mode or precision multimode links. The simplex construction means one fiber per plug; a duplex link needs two of these plugs. The free-hanging mount suits patch panel or in-line splice applications where a panel-mount receptacle is not used.
