采用半导体光放大器的交叉增益调制效应 ,通过全光方法 ,实现了 1.2Gbit/s光时分复用信号转换成2× 6 2 2Mbit/s波分复用信号的解复用。它同样具有波分复用信号到光时分复用信号波长变换的功能。
Using the cross-gain modulation effect of the semiconductor optical amplifier, the demultiplexing of the 1.2 Gbit / s optical time division multiplexed signal into the 2 × 6 2 Mbit / s wavelength division multiplexed signal is realized by the all-optical method. It also has the function of WDM signal to WDM wavelength conversion.
