Product details
3M's 8412-TM establishes new benchmarks in Fiber Optic Connectors - Adapters for underwater photonic systems, engineered to withstand 11,000-meter ocean depths. This marine-grade optical solution combines titanium strength with precision optics for deep-sea research and offshore energy applications.Configured as a Coupler, this submersible adapter features pressure-balanced oil-filled chambers that compensate for 110MPa hydrostatic pressure in hadal zone exploration equipment.The ST Receptacle interface employs corrosion-resistant Hastelloy springs maintaining constant mating force across 0-30 C temperature gradients in deep ocean currents.Conversion to ST Receptacle utilizes sapphire window technology that resists biofouling and maintains >90% transmittance after 5 years in seawater environments.Available in 12-Plex configurations, the product enables simultaneous power-over-fiber and data transmission for autonomous underwater vehicle docking stations.Supporting Multimode operation, the adapter enables blue-green wavelength transmission (450-550nm) with <0.1dB/km attenuation for underwater optical communication systems.Built for Panel Mount, Snap-In installation, the adapter's titanium alloy frame withstands 2,000kg/cm crushing forces encountered in deep-sea trench deployments.The Steel enclosure provides perfect galvanic compatibility with seawater while preventing crevice corrosion in high-salinity environments.With Dust Cap, the product includes integrated sacrificial zinc anodes that extend service life by 15 years in saltwater cathodic protection systems.The Almond housing incorporates bioluminescent-resistant pigments that remain visible under 1000m water depth lighting conditions for ROV operator identification.
