Data Network Connectors
Space-Rated Data Cable Connector Assemblies
Connectors and cable assemblies for all Ark data network physical layer connections
Purpose
Connectors and cable assemblies for all Ark data network physical layer connections
Context
Child of L2-CDH-BUS
Principles
- ▸Micro-D connectors (MIL-DTL-83513) for SpaceWire provide reliable high-density connections
- ▸Fiber optic connectors for radiation-immune long-distance data links
- ▸Hermetic feedthrough connectors maintain pressure boundary while passing data signals
- ▸Contact redundancy (multiple pins per signal) improves reliability
Typical implementations
- ▸Glenair Mighty Mouse micro-circular connectors
- ▸TE Deutsch space-rated fiber optic connectors
- ▸Amphenol Aerospace hermetic feedthrough assemblies
Lunar considerations
- ▸Dust contamination of optical fiber connectors during maintenance must be prevented
- ▸Connector cycling (mate/demate) during maintenance causes wear over 100 years
- ▸Thermal cycling affects contact resistance in metallic connectors
