OPTICAL TRANSCEIVER APPARATUS AND WAVELENGTH DIVISION MULTIPLEXING PASSIVE OPTICAL NETWORK SYSTEM

摘要

PTICAL T OPTICAL Embodiments of the present invention prox4dc a self joetien-eptieff14 veraiulenseelyer-medule. The-self-frijliction optical transteivcr module An optical transceiver apparatus includes a gain medium, a photoelectric converter, at least one affuyed-waide-grathig-AWG, and a partial reflection mirror. The at least one AWG includes two common ports and multiple branch ports. One of the two common ports functions as a signal sending port, and the other functions as a signal receiving port, where bandwidth of the signal sending port is less than that of the signal receiving port. The gain medium and the photoelectric converter are connected to one of the branch ports of the AWG. The .kWG and the partial reflection mirror are configured to cooperatively perform wavelength self-injection locking on an optical signal provided by the gain medium, and output the optical signal through the signal sending port. The AWG is further configured to demultiplex an optical signal received by the signal receiving port to a branch port. invention may effectively improve the performancc of the self injection optical transe ivef WDM-PON system is also provided FIGURE 3
