Organization: ITU-T
Publication Date: 1 July 2010
Status: active
Page Count: 26
scope:

This Recommendation deals with the characteristics of the optical fibre submarine cables used in [ITU-T G.973], [ITU-T G.973.1], [ITU-T G.974] and [ITU-T G.977].

An optical submarine cable can be used in:

- a repeatered optical submarine system;

- a repeaterless optical submarine system.

This Recommendation specifies the characteristics of the submarine cables which can be used in the deep and shallow waters.

This Recommendation covers:

- transmission characteristics of optical fibres in submarine cables including mechanical characteristics and resistance to the environment;

- characteristics of optical fibre submarine cables including mechanical characteristics and resistance to the environment and other electrical characteristics;

- transmission characteristics of single- and hybrid-fibre type elementary cable sections.
