1. Application:

A submarine communications cable is a cable laid on the sea bed between land-based stations to carry telecommunication signals across stretches of ocean. The first submarine communications cables, laid in the 1850s, carried telegraphy traffic. Subsequent generations of cables carried telephone traffic, then data communications traffic. Modern cables use optical fiber technology to carry digital data, which includes telephone, Internet and private data traffic.

Modern cables are typically about 25 millimetres (0.98 in) in diameter and weigh around 1.4 kilograms per metre (0.4 lb/ft) for the deep-sea sections which comprise the majority of the run, although larger and heavier cables are used for shallow-water sections near shore. [1] [2] Submarine cables connected all the world's continents except Antarctica when Java was connected to Darwin, Northern Territory, Australia in 1871 in anticipation of the completion of the Australian Overland Telegraph Line in 1872 connecting to Adelaide, South Australia and thence to the rest of Australia.

The submarine cables made by our company is armoured with high-tensile steel wire and used with technologies of water-proof and corrosion-proof to ensure the superior properties, test are performed in accordance with IEC60055, IEC60502 and methods recommended.

We are devoting ourselves these years to research and produce submarine cable, which can suit for seabed and sea area ambient condition, ocean physics characteristic and requirements of laying underwater, with waterproof, anti-corrosion, good machine performance and so on.
