ANALOG OPTICAL TRANSFERRING SYSTEM

摘要

PURPOSE: An optical transferring system is provided for a user to detect a fault generated in an uplink optical fiber or in a downlink optical fiber even if a slave unit does not detect a fault in the downlink optical fiber. CONSTITUTION: An analog optical transferring system comprises: a master unit(T1) and a slave unit(T2) mutually connected through 2-route optical fibers(F2, F1) for an uplink transferring and a downlink transferring; operating an interactive communication of an analog optical signal between the master unit and the slave unit by using the optical fibers; and a transferring and receiving device for an Radio Frequency(RF) of plural transmission lines to the analog optical signal multiplied by a radio frequency multiplying method such as a repeater for a mobile communication signal. Therefore, an automatic optical output controlling unit maintains the average optical output of the optical signal transferred to the opposite unit to an even level.
