An analog optical transmission system is provided to share a signal of a heterogeneous base station which is installed at another place. A donor(100) is installed at a base station of a first communication network(10). The donor converts RF(Radio Frequency) signals which have different sectors and are received from the base station into optical signals by using a different wave length, packs the converted optical signals in one, and transfers the packed signal to a remote(200) installed at a base station of a second mobile communication network through one optical line. The donor separates the optical signal received from the remote through one optical line into plural optical signals by using a CWDM demultiplexer, converts each optical signal into an RF signal, and applies the converted RF signal to the first mobile communication network. |
