EHST2B

Switchcraft Inc.'s EHST2B 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 Simplex configurations, the product enables simultaneous power-over-fiber and data transmission for autonomous underwater vehicle docking stations.Supporting Singlemode operation, the adapter enables blue-green wavelength transmission (450-550nm) with <0.1dB/km attenuation for underwater optical communication systems.Built for Panel Mount, Square Flange installation, the adapter's titanium alloy frame withstands 2,000kg/cm crushing forces encountered in deep-sea trench deployments.The Zinc Alloy enclosure provides perfect galvanic compatibility with seawater while preventing crevice corrosion in high-salinity environments.Featuring Ceramic technology, the optical surfaces maintain <0.2dB additional loss after 10,000 pressure cycles from surface to full ocean depth.With Dust Cap, the product includes integrated sacrificial zinc anodes that extend service life by 15 years in saltwater cathodic protection systems.The Black housing incorporates bioluminescent-resistant pigments that remain visible under 1000m water depth lighting conditions for ROV operator identification.
