摘要	A system includes a multiplexer having a pass-band and an optical network unit (ONU) optically coupled to the multiplexer. The ONU includes a tunable laser configured to continuously transmit an optical signal to the multiplexer in a burst-on state and a burst-off state. While in the burst-on state, the ONU is configured to tune the tunable laser to transmit the optical signal at a transmit wavelength within the wavelength pass-band of the multiplexer. The multiplexer configured to allow passage therethrough of the optical signal at the transmit wavelength. While in the burst-off state, the ONU is configured to tune the tunable laser to transmit the optical signal at a non-transmit wavelength outside of the wavelength pass-band of the multiplexer. The multiplexer configured to block passage therethrough of the optical signal at the non-transmit wavelength.
其他摘要	一种系统包括具有通带的多路复用器和光学耦合到多路复用器的光网络单元（ONU）。 ONU包括可调谐激光器，其被配置为在突发接通状态和突发断开状态下连续地将光信号发送到多路复用器。当处于突发接通状态时，ONU被配置为调谐可调谐激光器以在多路复用器的波长通带内的发射波长处发射光信号。多路复用器被配置为允许光信号在发射波长处通过。当处于突发关闭状态时，ONU被配置为调谐可调谐激光器以在多路复用器的波长通带之外的非发射波长处发射光信号。多路复用器被配置为阻止光信号在非透射波长下通过。
