| Abstract: | In the paper, based on analysis of PON characteristics, importance of optical link supervision technology was introduced firstly. Then, three implementation technologies of optical link supervision in PON system were investigated in detail. Based on synthetization of the cost, benefit, realizability, etc., the double-end optical transceiver parameter measurement is proposed to be the best way to achieve optical link supervision currently. In addition, in the paper measurement methods of received power in th... |
