New in-line dry-mate connector offers more protection for marine fiber optics

TE Connectivity has introduced the DEUTSCH high density optical in-line dry-mate connector. Developed from subsea and high-pressure/high-temperature (HP/HT) fiber optic technology, it was designed to withstand harsh offshore environments and is ideal for applications that need maximum space and weight savings.

The DEUTSCH high density in-line connectors are said to offer a cost-effective solution for multichannel fiber optic management, packing 12 to 24 fiber optic channels in standard versions and up to 48 upon request. With operating temperatures between -30° and 121°C (-22° and 251°F) using the HT fiber, and bulkhead receptacles that are rated to withstand 450 bar (6,536 psi) of differential pressure, this multichannel fiber optic connector maintains stable performance during strain and temperature monitoring. Low insertion loss and back reflection (≤ negative 45dB) are achieved using angled physical contacts. In addition, the system maintains integrity in the face of flooding due to a dual sealing bulkhead receptacle.

“The new high density optical in-line dry-mate connectors are built from the same reliable technology used in multi-fiber optic HP/HT feedthrough systems, so engineers can expect a familiar interface that’s compatible with TE’s established DEUTSCH dry-mate connector,” said Jérémy Calac, product manager for marine oil & gas. “They are also optimized for offshore renewables systems, subsea flexibles and umbilical terminations.”
