OPTICAL FIBER WIRELESS ACCESS SYSTEM, CENTRAL STATION DEVICE, BASE STATION DEVICE, EXTRACTION METHOD AND COMMUNICATION METHOD

摘要

In order to provide an optical fiber wireless access system capable of separating an uplink signal and a downlink signal without using a frequency filter, this optical fiber wireless access system comprises a central station device 100 and a base station device 110 that are connected by an optical fiber. The central base station 100 is provided with a photoelectric conversion unit 101 that converts a downlink wireless signal into a downlink optical signal by intensity modulation, a light receiving unit 102 that receives a multiple optical signal generated by intensity modulating the downlink optical signal transmitted to the base station device 110, and an extraction unit 103 that extracts an uplink wireless signal. The base station device 110 is provided with a multiplexing unit 111 that generates the multiple optical signal by intensity modulating the downlink optical signal transmitted from the central station device 100 using the uplink wireless signal.
