Deep-sea watertight opto-electrical composite cables are integrated transmission solutions engineered for harsh deep-sea environments. They integrate power delivery, signal transmission and high-speed fiber-optic communication functions, serving as the vital lifeline for deep-sea exploration, marine engineering and underwater operation systems.

Their design ensures stable and reliable power & signal transmission. Meanwhile, lightweight and all-in-one structure drastically lowers cable deployment difficulty and system maintenance costs. These cables are core components for constructing modern subsea observation networks and remotely operated vehicles (ROVs).
