Moog Focal offers standard pressure-tolerant electronics, optical couplers, and fibre optic transceivers (SFPs) for demanding subsea applications. These devices can withstand extreme ocean depths when installed in a pressure-balanced, oil-filled (PBOF) enclosure with a standard depth rating of up to 4000 m. PBOF technologies can increase connector space and reduce or eliminate the costs of large one-atmosphere housings.
Moog Focal has been providing pressure-tolerant products since 2007, with thousands of components in the field. Pressure-tolerant solutions exist for HD video, Gigabit Ethernet, analogue video, serial data, optical couplers (WDM, CWDM, splitter), and fibre optic transceivers (SFP up to 4.25 Gbps, CWDM, and bidirectional versions).
Rigorous design testing is conducted on all new products to ensure optical and electrical performance at rated pressure and during rapid pressure cycling. Qualification and design tests are redone with any significant changes in the build process or component structures.
Pressure-tolerant products must be enclosed in a subsea junction box or enclosed with oil. Focal has tested compatibility with many typical oils used in the marine industry and continues to validate additional fluids as new applications emerge.
