Problems solved by technology

However, it also has obvious defects, and its main limitations are as follows: 1. The same body manufacturing, when there is a problem with one line in the cable, it cannot be replaced independently, and it may cause a short circuit of the cable when it encounters external damage such as lightning strikes and corrosion. Generate a large current, damage the equipment and damage the cable; 2. The shielding between the cable core and the fiber core is complicated, and the signals are easy to interfere with each other, which affects the use of the cable; 3. Long-distance power transmission is for high voltage Or ultra-high voltage (36kV ~ 500kV) demand, so that the corresponding equipment is required to generate output power at the user control end (power output end), and at the same time, corresponding circuit modules suitable for high voltage are also required at the power receiving end to realize power output. The processing and use of the system increases the volume, weight and complexity of the system, which limits the portability of the system, especially the user control end; 4. Since the power supply cable needs to use metal cores, such as copper wires, this makes the overall photoelectric composite cable The weight of the photoelectric composite cable is relatively large (the weight of the existing photoelectric composite cable is generally greater than 100 kilograms per kilometer). Difficult to use for rapid temporary submarine local area network laying and power and signal exchange for portable rapid underwater mission execution systems
