PURPOSE: An analog optic bi-directional amplification system is provided to amplify and transmit only preference signal by removing various interference. CONSTITUTION: An analog light amplification system comprises a head unit(201) and a remote unit(206). A head unit is interfaced with a base station/bi-directional amplifier(200). The head unit plays a role as plural remote units(206,213~215) which execute optic amplification. The remote unit is connected with an optical line through the head unit(212). The remote unit is interfaced with a terminal.
