Abstract: Provided are a passive optical network system and a method of transmitting a broadcasting signal in the same system. A central office (CO) generates a broadcasting signal and a downstream optical data signal using a coding method guaranteeing a run-length, multiplexes the downstream optical data signal and the broadcasting signal, and transmits the multiplexed downstream optical data signal and broadcasting signal. A remote node (RN) transmits the multiplexed downstream optical data signal and broadcasting signal received from the CO to one or more optical network units (ONUs). A gain medium, which is located on a transmission line between the CO and the RN, amplifies the broadcasting signal using the downstream optical data signal as a pump light source. Accordingly, a high gain can be obtained by amplifying the broadcasting signal using the gain medium located on the transmission line without a separate pump light source.

Abstract translation: 提供了一种无源光网络系统和在相同系统中发送广播信号的方法。 中央办公室（CO）使用保证游程长度的编码方法生成广播信号和下行光数据信号，复用下行光数据信号和广播信号，并发送多路复用的下行光数据信号和广播信号。 远程节点（RN）将从CO接收的多路复用的下行光数据信号和广播信号发送到一个或多个光网络单元（ONU）。 位于CO和RN之间的传输线上的增益介质使用下行光数据信号作为泵浦光源放大广播信号。 因此，通过使用位于传输线路上的增益介质放大广播信号而无需单独的泵浦光源，可以获得高增益。
