Installation zone RECOMMENDATION

OCC’s ruggedized ST connector and ST adapter products represent one of the best single-fiber connection systems available to industries where the ability to withstand extreme temperature change, shock, vibration, or corrosion is required. We offer both commercial-off-the-shelf (COTS) ST’s for harsh environment applications and the fully qualified, Military ST (MIL) that meets or exceeds 100% of the military specification MIL-DTL-83522E.

Applications

Navy Shipboard Systems
Army and Marine Corp TAC COM
Pierside/Ship-to-Shore Communications
Disaster Recovery Emergency Communications
Commercial and Military Antennas and Radars
Mobile Tactical Shelters
Mobile or Remote Broadcast Harsh Environments
Oil and Gas Industries

Features

Nickel-plated brass or stainless steel options are available
Available to support single-mode and multimode fibers
Accommodate fiber cables with outer jackets from 2.0mm to 3.0mm outer diameters
The locking version features washers that prevent inadvertent optical disconnect due to stress on the cable, and are more resistant to cable pull force or repeated shock and/or vibration
Up to 50 lbs. of pull strength protection is readily achievable using standard termination techniques
A convenient screw-on boot feature eliminates the need for a cumbersome boot tool
The MIL ST features a higher spring force that passes Navy High Shock (explosive) requirements
A slightly lower spring force allows OCC’s COTS ST connectors to provide the same optical performance as the MIL ST in standard shock and vibration while also allowing successful coupling with composite adapters and devices
OCC’s ST’s feature a closed entry design which provides both easier mating when new and retains its mating profile for easier mating over repeated in-field mating cycles
Ability to inter-mate with ST connectors in the field
