The existing submarine photoelectric composite cable realizes the information loop transmission through optical fiber, and the electrical energy loop through the conductor assembly transmission.

In addition, when the existing photoelectric composite cable works for a long time, the temperature rises due to the loss of the line under the power-on condition and the heat is emitted. In a long-term high temperature environment, the service life of the optical fiber will be reduced and the loss of the optical fiber will increase, thereby affecting the service life of the cable And signal transmission quality.
