摘　　要：提出利用复用信号的时间不均匀性， 采用主动光纤锁模激光器， 直接从复用后的信号中提取出复用前的时钟光脉冲。考虑到电的时分复用与光的时分复用在机理上的一致性， 故初步用电时分复用信号进行实验， 成功地从时分复用信号中得到了复用前的时钟光脉冲［１］。此处电的时分复用所得的结论适用于光的时分复用。A scheme of using a mode locked fiber ring laser and taking the advantage of the time unevenness of the multiplexed signal to obtain the clock of the single channel from the optical time division multiplexing (OTDM) signal is proposed. In experiment, the electronic time division multiplexing (TDM) signal is used because it is identical with OTDM signal in principle. The optical clock of the single channel is obtained successfully using the electronic multiplexed signal. The result can be applied in all optical clock recovery of the OTDM system.
