The simulated optical fiber repeater distribution system comprises a near-end machine, a relay machine, a far-end machine and a remote feed unit, wherein signal transmission is realized among the near-end machine, the relay machine and the far-end machine by adopting optical fibers; the far-end machine power supply is realized between the relay machine and the far-end machine through the remote feed unit; the near-end machine comprises a signal processing module, a power supply module, an optical splitter and an MODEM module; the ports of the optical splitter and the MODEM module are connected with the port of the signal processing module respectively; the relay machine comprises a signal processing module, a backup signal processing module, an optical splitter and a backup optical splitter; and the far-end machine comprises an optical splitter, an optical emitter, an optical receiver, a backup optical receiver, a combiner, a frequency shift key (FSK) transceiver, a downlink amplifying unit, an uplink amplifying unit, a monitoring unit, a duplexer and a lamp pole antenna. The simulated optical fiber repeater distribution system is convenient for concentrative power supply, high in integration degree and low in construction difficulty; and the coverage end has a bypass function.

Description

technical field [0001] The invention belongs to the field of optical fiber repeaters, specifically, it adopts optical fiber communication transmission, a near-end machine couples base station signals, and an analog optical fiber repeater distribution system using an integrated coverage antenna of a remote feed unit between a repeater and a remote machine . Background technique [0002] With the continuous development of 3G communication technology, the demand for wireless network construction and wireless coverage is increasing day by day. At the same time, the country is carrying out the policy of "light into copper and back out", and the optical fiber communication system has been more and more widely used. [0003] Compared with digital optical fiber repeater products, analog optical fiber repeater products have the advantages of mature technology, simple equipment, cheap price, etc., and are compatible with existing analog signals, so they are still widely used.
