It uses a threaded coupling for secure mating and is free-hanging (in-line) with a 3.1mm cable diameter acceptance. The connector includes a dust cap and strain relief as standard features, with a black boot and silver nickel-plated copper alloy body. The ferrule is stainless steel, and the connector is rated for 200 mating cycles. ## Cable Fit and Termination Notes This plug accepts a 3.1mm cable diameter — a specific fit that must match the cable jacket OD for proper strain relief and sealing. The simplex configuration means one fiber per connector. The threaded coupling provides vibration-resistant mating, typical for FSMA-style interconnects in test equipment and industrial fiber links.","metaTitle":"TE 504566-2 FSMA Simplex Plug, Multimode, Obsolete","metaDescription":"TE Connectivity 504566-2 OPTIMATE FSMA simplex plug, multimode, 3.1mm cable, threaded coupling.
