FC Simplex Plug for 900 µm Tight-Buffer Fiber
The Molex 1060533500 is an FC simplex plug from the 106053 series, designed for multimode fiber terminations. It accepts a 0.9mm cable diameter, which corresponds to standard 900 µm tight-buffer fiber used in patch cords and pigtails. The connector uses a Zirconia ferrule for precise core alignment and a threaded coupling nut for secure mating — the FC bayonet-style interface common in test equipment, telco central offices, and high-vibration datacom racks. The housing is silver-colored PBT with a black boot and includes a dust cap and strain relief as standard features.
Cable Fit and Termination Notes
The 0.9mm cable diameter matches the 900 µm buffer diameter of common multimode tight-buffer fibers (the fiber cladding is 128 µm, per). The free-hanging mount means this is a field-terminable plug — no PCB footprint to worry about. The threaded fastening gives a positive mechanical lock, so the connector stays mated under cable pull and vibration. The included dust cap protects the ferrule when unmated; the strain relief keeps the fiber from bending at the backshell entry radius.
