Abstract

The invention provides a submarine optical cable. The optical cable comprises an optical unit located at the center and an outer protective layer located on the periphery, an armor layer, a pluralityof conductor layers and a plurality of insulating layers are arranged between the optical unit and the outer protective layer, the armor layer is arranged on the outer layer of the optical unit, the number of the conductor layers is consistent with that of the insulating layers, the conductor layer and the insulating layer are arranged at intervals, the conductor layer abuts against the armor layer, a reinforcing layer is further arranged between the outermost insulating layer and the outer protective layer, and sensing optical fibers are distributed on the outer layer of the reinforcing layer. The sensing optical fiber unit is additionally arranged on the basis of an existing submarine optical cable structure, underwater sound, vibration, impact, temperature changes and other signals neara submarine optical cable can be monitored through corresponding detection instruments and detection systems, the data collection range and data collection quantity of a submarine observation networksystem are increased, and the functions of loop transmission of electric energy and information, information acquisition, routing monitoring, eavesdropping prevention and the like can be realized.

Description

technical field [0001] The invention relates to the technical field of optical cable design, in particular to a submarine optical cable. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] The submarine observation network is a complete set of observation equipment deployed on the seabed for a long time, and is considered by scientists to be the third platform for observing the earth after the ground and space. The submarine observation network consists of shore base stations, submarine optical cable networks (including submarine cables, repeaters, splitters, etc.), junction boxes, observation instrument equipment platforms, and various ocean observation equipment. It is transmitted to the submarine junction box system in the form of high-voltage direct current, and the lat...
