Watertight Optoelectric Cables · Marine & Subsea

Neutrally buoyant single-mode fibre tether, G657A2, 100 kg LCP braid strength member, 3.5 mm foamed TPU sheath, supplied in 1000 m lengths with connectors.
Product overview
In advanced fields such as underwater survey and communication, long-distance single-core buoyant optical fibre plays an essential role. Its buoyancy characteristics make it purpose-designed for the underwater environment, where it forms a key link in ocean monitoring, underwater communication and subsea cable systems: whether helping scientists investigate the ocean, maintaining stable communication between underwater vehicles and control centres, or optimising the layout of subsea cables, it is indispensable.
