摘要

我们通过数值模拟表明，在高速相干50% RZ-BPSK系统中，通过抵消滤波器(相当于激光失谐)可以大大降低紧光滤波的影响。我们表明，通过将滤波器的带宽偏移一半，在OSNR为12 dB的情况下，系统性能在计算的“Q”中提高了> 2.5 dB。

Performance evaluation of strongly filtered asymmetric 42.7 Gb/s coherent 50%RZ-BPSK system

We show, by numerical simulation, that the impact of tight optical filtering in high speed coherent 50% RZ-BPSK systems can be greatly reduced by offsetting the filter (equivalent to laser detuning). We show that by offsetting the filter by up to half the filter bandwidth, that system performance is improved by > 2.5 dB in the calculated `Q' for an OSNR of 12 dB.
