Bayonet-lock ST fiber jumpers (SM/MM) with low loss, high stability, and multiple jacket/armor options for telecom, campus, and industrial networks.
The ST Jumper Series is a reliable, bayonet-lock fiber patch cord family designed for telecom, campus LAN, industrial control, and instrumentation environments. Using 2.5 mm ferrules with secure twist-lock coupling, these jumpers deliver stable performance in legacy and mixed-vendor networks, with options for single-mode and multimode fiber, simplex or duplex builds, and standard or armored cables.
