我们实验展示了一种通道复用、双向、10gb /s/λ、长程密集波分复用无源光网络（DWDM-PON）和一种基于光热噪声的可调谐激光器自动波长控制方法，该方法用于无色光网络单元（ONU）。在50 GHz DWDM网格上实现了42公里范围、信道复用、全双工、10gb /s传输。在信道复用系统中，采用不同的光信-瑞利-背向散射噪声比（OSRBNRs）和不同的中心波长位移（WSs）对传输性能进行了测试。
We experimentally demonstrate a channel-reuse, bidirectional, 10 Gb/s/λ, long-reach dense wavelength-division-multiplexing passive optical network (DWDM-PON) and an optical beat noise-based automatic wavelength control method for a tunable laser used in a colorless optical network unit (ONU). A 42 km reach, channel-reuse, full-duplex, 10 Gb/s transmission on a 50 GHz DWDM grid is achieved. Transmission performance is also measured with different optical-signal-to-Rayleigh-backscattering-noise ratios (OSRBNRs) and different central wavelength shifts (WSs) between upstream signal and downstream signal in the channel-reuse system.
