Abstract

We consider a communication line without dispersion compensation. A new type of a phase-modulated format is proposed, in which Gaussian pulses with a varying off-center chirp are transmitted. It is found that there is a time shift of pulses relative to each other. Numerical simulations using the 8-PSK format as an example show that this method of generating pulses at the beginning of the line leads to less signal distortion, even with relatively small chirps.

无色散补偿的高速光链路上偏心啁啾数据传输的相位调制格式

摘要

我们考虑没有色散补偿的通信线路。提出了一种新型的相位调制格式，其中传输具有变化的偏心线性调频的高斯脉冲。发现脉冲之间存在相对时移。以 8-PSK 格式为例的数值模拟表明，这种在行开头生成脉冲的方法即使在相对较小的线性调频脉冲的情况下也能减少信号失真。
