ST Connectors

Amphenol Fiber Optics ST Connectors utilize a bayonet-style mating concept to provide a secure and robust coupling mechanism. The enclosed spiral-slotted coupling nut allows easy insertion in densely packed patch panels. Amphenol Fiber Optics ST Connectors are ideal for telecom, data premise installation, and test lab applications. ST connectors meet high-performance standards for increasing product repeatability and exceeding industry standards. These connectors are available with a plastic or die-cast body and a ceramic or stainless steel ferrule.
