Problems solved by technology

[0005] The downhole communication system of drilling rigs based on optical fiber communication technology can solve the above problems. However, the downhole environment is harsh, and the existing downhole communication devices cannot be used normally in the high temperature and high pressure downhole environment, which directly affects the normal operation of the entire downhole communication system and limits drilling.
