It accepts both Singlemode and Multimode fibers, so it works across singlemode and multimode link budgets without swapping hardware. The metal ferrule gives the alignment sleeve better dimensional stability than a plastic one — important when you're mating connectors repeatedly in a patch panel or test setup. ## Mounting and Build Details The adapter mounts in a panel cutout using both a flange and snap-in clips — the flange takes the axial load from cable tugging, while the snap-in holds it in place during installation. A dust cap is included to keep the alignment sleeve clean when the port is not in use.","metaTitle":"TE 5502781-3 SC-FC Simplex Adapter, Beige, Obsolete","metaDescription":"TE 5502781-3 SC-FC simplex fiber adapter, beige, metal ferrule, panel mount.
