| 摘要 |
A point-to-multi-point passive optical network (PON) includes: an optical line terminal (OLT) comprising an optical transceiver for generating a downstream optical signal and a monitoring signal and for detecting an upstream optical signal; a plurality of optical network units (ONUs) for detecting the downstream optical signal, reflecting the monitoring signal to the OLT, and transmitting a data-modulated upstream optical signal in a designated time slot; and an optical fiber for connecting the ONUs and the OLT.
