Overview
The AFL FAST-ST-MM62.5-6 is a set of 6 field-installable ST connectors designed for multimode 62.5µm OM1 fiber optic cabling. These connectors feature a pre-stubbed, factory-polished ferrule, which eliminates the need for field epoxy application, polishing, or extensive training during termination. They are ideal for quick, high-performance repairs and installations in premise environments.
Engineered for precision, these connectors utilize a mechanical alignment system to ensure low insertion loss. Each connector includes a factory-installed wedge clip that is removed upon termination completion, and the design allows for re-insertion of the fiber up to three times, providing flexibility during field maintenance.
