SOUTH BAY CABLE southbaycable.com

South Bay Cable (SBC) specializes in custom cable engineering and manufacturing.

Advances in material chemistry have increased SBC’s ability to build cables that are lighter and stronger than ever before, which in turn allows for exploration at greater ocean depths. New technologies in ? ber optics have allowed

SBC to build cables that are sensors themselves.

SBC has new equipment currently coming online, including two new Davis-Standard extruders. Additional improvements and increased capacity are on the horizon. 74 September/October 2026
