8408BK-DCM

The 8408BK-DCM by 3M 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 16-Plex formats, the product enables redundant optical links with <1ps skew between channels for fault-tolerant satellite crosslinks.Optimized for Multimode 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, Snap-In installation, the adapter features zero-outgassing adhesives and vacuum-compatible materials meeting NASA-STD-6016 requirements.Manufactured from Steel, the housing demonstrates <0.1% gas permeability after 10 years in vacuum, preventing optical surface contamination in deep space probes.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.
