Abstract

The invention discloses a composite submarine cable. The composite submarine cable comprises a cable core body, the cable core body comprising an electric unit and a communication optical unit. The composite submarine cable is characterized in that the composite submarine cable further comprises an environment sensing optical unit and an armor layer formed by twisting armor wires, the armor layerwraps the outer side of the cable core body, and the environment sensing optical unit is arranged in an armor gap of the armor layer. The environmental sensing optical unit comprises at least one environmental sensing optical cable. According to the composite submarine cable, the electric unit transmits electric power in a point-to-point manner, and the communication optical unit realizes point-to-point communication transmission. Moreover, the environment sensing optical cable realizes coastal detection and water area environment sensing in a routing range, realizes multifunctional combination of communication, electric power and detection, realizes multiple purposes, saves the cost of repeated laying and the investment of primary equipment, and reduces the routing conflict of repeated laying in the same water area.

Description

technical field [0001] The invention relates to the technical field of submarine cables, in particular to a composite submarine cable. Background technique [0002] With the continuous leapfrog development of my country's marine economy, various types of marine communications and underwater detection and detection fields have continuously increased the requirements for the composite transmission capacity of traditional submarine optical cables, and the demand for real-time online monitoring of the seabed has increased, and developed products that meet more functions. The composite submarine optical cable can not only greatly reduce the construction cost of various detection and communication platforms, but also help to promote the construction of my country's submarine online observation network and improve the utilization and protection of my country's marine resources. [0003] At present, there are two main types of submarine cables that are widely used. One is the traditi...
