Optical transmission system with receiver using full optical clock recovery

在一种光传输系统中，发射机(2)产生一个时分多路复用脉冲序列，通过光传输媒体(4)发送给接收机(6)。在接收机(6)中，所接收的光多路复用信号加到光多路分路器(30)和时钟恢复装置(48)上。时钟恢复装置(48)产生光时钟脉冲，用来控制光控光开关(32，...，38)，对光信号进行多路分路。光时钟恢复电路基于由所接收的光信号加以模式锁定的激光器。模式锁定激光器包括一个光放大器(50)，它的输出端由包括极化控制器(52)、饱和吸收器(61)、耦合器(56)和可调延迟器(51)的反馈回路接至它的输入端。饱和吸收器(61)包括与一个次级回路连接的3dB、90°耦合器(54)。所述次级回路包括衰减器(...
