This adapter uses a metal ferrule for precision alignment and a black PBT glass-filled housing rated UL94 V-0. It mounts to a panel via flange or snap-in, and includes a dust cap to protect the optical surfaces when not mated. The 5503137-1 is officially obsolete. No direct replacement has been listed by TE Connectivity. Buyers should evaluate alternative SC-ST duplex adapters from the same or other manufacturers for new designs. The adapter is designed for panel mounting with either a flange or snap-in retention. The flange provides a positive stop against the panel face; the snap-in feature allows tool-less installation into a rectangular cutout. The metal ferrule ensures stable fiber alignment across temperature and vibration cycles typical in telecom or industrial enclosures.","metaTitle":"TE 5503137-1 SC-ST Duplex Adapter, Singlemode/Multimode","metaDescription":"TE Connectivity 5503137-1 SC-ST duplex fiber adapter.
