503273-1

The 503273-1 by TE Connectivity AMP Connectors 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 ST 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 ST Receptacle, the adapter's kinematic mounting system ensures micron-level repeatability for telescope optical bench alignments in space observatories.Available in Duplex formats, the product enables redundant optical links with <1ps skew between channels for fault-tolerant satellite crosslinks.Optimized for Singlemode transmission, the adapter supports both 1064nm laser ranging and 1550nm communication wavelengths with <0.2dB wavelength-dependent loss for multi-function space systems.Engineered for Panel Mount, Flange (2 Hole) installation, the adapter features zero-outgassing adhesives and vacuum-compatible materials meeting NASA-STD-6016 requirements.Manufactured from Polyphenylene Sulfide (PPS), the housing demonstrates <0.1% gas permeability after 10 years in vacuum, preventing optical surface contamination in deep space probes.The Metal 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.Black coding follows ECSS-Q-ST-70-21 standards for visual identification in extravehicular activity (EVA) repair scenarios under full sunlight conditions.
