Features & Benefits

Applications

The ST series of lightwave connectors are specially designed for distribution applications and are fully compatible with

existing ST type hardware. Five connector styles are available in both the multimode and singlemode versions. The

screw-on captivation mechanism, in the long boot style, provides excellent KEVLAR retention without the expense and

inconvenience of crimp tools. If the crimping method of KEVLAR retention is preferred, 3 options are available. A long boot

style is designed to provide superior strain relief while the short boot style is designed for small bend radius applications

where space is limited. For sensitive applications where controlled and managed bends are required, the 90° boot is the

answer. A boot for 900µm buffered fiber is also available.

High quality, pre-polished and pre-radiused zirconia ceramic ferrules are combined with the latest engineering polymers and

metals to produce the ST connectors. Pre-polished ferrules minimize the polishing times and provide a consistent ferrule end

face geometry. When combined with the Molex termination kit and methods, the Molex ST connectors produce superior results

both in the factory and in the field.

A broad range of ST adapters are available to compliment the connectors. Metal or polymer versions are available with either

the extremely precise zirconia ceramic, the rugged phosphor bronze or the cost effective polymer alignment sleeves.
