4× 10Gb s非等幅编光时分复用 (OTDM)传输系统采用增益开关分布反馈式激光器 (GS DFB)产生超短光脉冲 ,通过色散补偿光纤 (DCF)和梳状色散光纤链 (CDPF)实现了脉冲的线性和非线性压缩 ;利用啁啾光纤光栅实现色散补偿 ;在接收端 ,利用电吸收调制器 (EAM)实现了光时分复用信号的解复用 ;同时采用非等幅编码方案提取帧时钟。整个系统经过 12 2km的G .6 5 2光纤传输之后 ,误码率小于 10 - 9。
The 4 × 10Gb s non-constant-amplitude optical time division multiplexing (OTDM) transmission system uses an ultra-short optical pulse generated by a gain switching distributed feedback laser (GS DFB). The dispersion compensation fiber (DCF) and the comb-shaped dispersion fiber chain (CDPF) The chirped fiber grating is used to realize the dispersion compensation. At the receiving end, the EAM is used to demultiplex the optical time-division multiplexed signal. At the same time, the non-equal amplitude coding scheme Extract the frame clock. The whole system after 12 2km G. 6 5 2 optical fiber transmission, the bit error rate of less than 10 - 9.
