Problems solved by technology

[0004] What the present invention aims to solve is that when the existing optical transport network equipment performs the remote work between the baseband processing unit and the radio remote unit, the data delay is relatively large, and the transmission is affected when the data is overloaded, which easily leads to the problem that normal communication cannot be performed.
