The TE Connectivity 504566-7 is an OPTIMATE series FSMA plug, built for multimode fiber optic terminations in a simplex, free-hanging (in-line) configuration. Rated for 200 mating cycles, it is suited for test equipment, industrial networking, and legacy telecom links where the FSMA interface is still in service.
Construction and Cable Fit
The body is copper alloy with nickel plating, the ferrule is stainless steel, and the boot is black. Accepts a 3.1 mm cable diameter — a specific fit, not a range.
Lifecycle: Obsolete — Sourcing the 504566-7
The 504566-7 is officially listed as Obsolete. No direct replacement or cross-reference is recorded in the TE OPTIMATE series. For a potential alternative, a review of the FSMA interface standard and the specific cable diameter is recommended.
