Since ocean equity areas are typically more than 20 nautical miles from shore, the observed information needs to be transmitted over submarine cables to a control center onshore. The remote underwater fixed observation equipment is difficult to maintain regularly due to the fact that the underwater fixed observation equipment is far from the coast, and the equipment needs to have good protection capability. The observation equipment is generally designed with a thick and heavy protective cover when being built and installed, and can not be accidentally knocked and damaged in the using process. However, the optical cable for information transmission is in a suspended transition under the action of the marine environment for a long time, particularly from the underwater fixed equipment to the seabed, and is required to be protected under the action of water flow for a long time.
