HSC2-4A(51)

The HSC2-4A(51) by Hirose Electric Co Ltd redefines Fiber Optic Connectors - Adapters technology for space-grade optical communications, meeting NASA-level reliability standards for satellite constellations. This radiation-hardened solution combines aerospace materials with precision optics for uninterrupted operation in LEO and GEO orbits.As a Coupler, this space-qualified component features monolithic ceramic construction that survives 100krad TID (Total Ionizing Dose) exposure, making it ideal for multi-year satellite missions.The SC Receptacle connection utilizes gold-diffused hermetic seals that maintain <0.5dB insertion loss after 500 thermal cycles (-196 C to +125 C) in lunar surface equipment.When converting to SC Receptacle, the adapter's kinematic mounting system ensures micron-level repeatability for telescope optical bench alignments in space observatories.Available in 4-Plex formats, the product enables redundant optical links with <1ps skew between channels for fault-tolerant satellite crosslinks.Engineered for Panel Mount, Snap-In installation, the adapter features zero-outgassing adhesives and vacuum-compatible materials meeting NASA-STD-6016 requirements.Manufactured from Synthetic Resin, the housing demonstrates <0.1% gas permeability after 10 years in vacuum, preventing optical surface contamination in deep space probes.The Copper Alloy ferrules incorporate radiation-resistant dopants that maintain <0.1dB/km additional loss after 10 years in Van Allen belt radiation environments.With Dust Cap, the product includes integrated micrometeoroid shielding that maintains optical performance after impact with 1mm particles at 10km/s orbital velocities.Blue coding follows ECSS-Q-ST-70-21 standards for visual identification in extravehicular activity (EVA) repair scenarios under full sunlight conditions.
