TIME-DIVISION-MULTIPLEXED PASSIVE OPTICAL NETWORK AND DYNAMIC BANDWIDTH ALLOCATION METHOD THEREOF

摘要

Time-division-multiplexed passive optical network in accordance with the present invention is terminated with a light beam; It includes a plurality of secondary optical splitter connected to the plurality of optical network units and respectively 1: 2, and wherein each of the secondary optical splitter includes a pair of upwardly by dividing the corresponding upstream optical signal input from any one of a pair of optical network units connected generating local base station, and transmits the one of the pair of the upstream optical signal to the termination to the light beam and transmits the other of the pair of upstream optical signals to the other of the pair of the optical network unit and an optical signal; Respectively, only when not receiving the uplink optical signal from said local base station includes a plurality of optical network units to generate and output the upstream optical signal. ; Time-division multiplexing passive optical network, an optical splitter, a dynamic bandwidth allocation
