Space ST Fiber Optic Connector
Physical Contact Connectors – MIL-ST Connectors
Amphenol Fiber Systems International (AFSI) offers a fiber optic MIL-STD-83522 style connector and strain relief boot compliant to NASAEEE-INST-002 material guidelines for space applications. AFSI’s Space ST connectors were tested to ASTME595 to evaluate the boot’s out-gassing properties and are available for all of the popular fiber sizes.
The Space ST is a M83522 style variant, which features a higher spring force than commercial ST connectors, allowing it to meet the shock and vibration requirements of MIL-C-83522. Stainless steel construction provides excellent mechanical strength and superior corrosion resistance. A companion adapter is available to support bulk head applications.
