Description

[0002] Currently in the field of marine scientific research, the demand for long-term real-time remote observation of the underwater environment is becoming increasingly urgent. Since cable communication systems are difficult to achieve long-distance, large-capacity data transmission, it is necessary to use optoelectronic composite submarine cables to achieve this. The optical fiber is used to transmit data and the wires are used to transmit energy. In order to realize data and power transmission between shore-based and underwater equipment, the optical fiber and wires in the optoelectronic composite submarine cable must be separated by an underwater optoelectronic separator and then connected to the underwater equipment.
