The ST Connector provides a versatile, reliable, and cost-effective fiber optic termination method. The design of the ST Connector enables it to be easily inserted and removed. The Fiber Optic ST style connector utilizes a bayonet twist-lock connection with 2.5mm ferrule. Available in singlemode and multimode, the ST style connector features reliable and durable field installation. The design of this Fiber Optic ST connector enables installers to crimp the back of the body directly onto the cable jacket and Kevlar?.
