The present invention is applicable to the field of communications, and provides a distributed base station signal transmission system and a communication system. The system includes a base band unit and a remote radio unit, and further includes a first multiplexing and demultiplexing unit and a second multiplexing and demultiplexing unit, which are respectively configured to multiplex and output a downlink signal emitted by the base band unit and demultiplex an uplink signal sent by the remote radio unit to the base band unit, and, multiplex and output an uplink signal and demultiplex a downlink signal to the remote radio unit; a first colorless optical module receives and parse the uplink signal and generate the downlink signal; and a second colorless optical module is configured to receive and parse the downlink signal and generate the uplink signal. The present invention requires only one or a pair of fibers to implement interconnection between BBUs and RRUs, and does not need to use a large number of fibers and a metro wavelength division multiplexing network. The colorless optical module is capable of providing a random wavelength, has high adaptability, and is easy to install and maintain. The system can reuse existing fiber resources to implement interconnection between the BBUs and the RRUs, which facilitates network construction and has low costs. |
