The ST APC 0.9mm Connector is a compact, high-precision solution for single-mode simplex fiber applications using a 0.9mm tight-buffered cable. It features a bayonet-style twist-lock coupling for quick and secure connections, along with an APC-polished ferrule to ensure low insertion loss (≤0.25dB) and return loss ≥60dB.
Its simple structure with snap ring, green boot, and robust spring assembly supports over 1000 mating cycles, making it ideal for test equipment, telecom networks, and instrumentation setups where reliable, space-saving connectors are required.
