Product details

FSMA Plug for Multimode Fiber — Now Obsolete

The TE Connectivity 504566-1 is an OPTIMATE series FSMA fiber optic plug, designed for multimode simplex termination. It uses a threaded coupling nut for secure mating, accepts a 3.1mm cable jacket, and includes both a dust cap and a strain relief boot as standard. Typical insertion loss is rated at -1.3dB.

TE Connectivity has officially classified the 504566-1 as Obsolete. No direct form-fit-function replacement is listed by the manufacturer. Buyers should verify the fiber termination requirements — FSMA is a legacy interface, and a migration to a modern connector such as an SC or LC simplex may be the practical path forward.

What You Get in the Package

The connector ships in bulk packaging and includes a black strain relief boot and a dust cap fitted over the ferrule. The body is nickel-plated copper alloy, the ferrule is stainless steel. The boot colour is black; the housing body is silver.
