摘要
在160 Gb/s光时分复用(OTDM)系统中，带内四波混频(IFWM)效应是影响系统性能的因素之一。分析了IFWM效应对160 Gb/s光时分复用传输系统性能的影响，对采用强色散管理的方法抑制IFWM效应进行了理论分析和实验验证。传输链路采用大色散斜率的标准单模光纤(SSMF)和色散、色散斜率补偿光纤混合的色散管理方式，能够很好地抑制“1”比特处的脉冲幅度变化和“0”比特处产生的寄生脉冲，提升系统的整体性能。在不需要前向纠错和功率代价小于3.6 dB的条件下，实现了较长时间(时间大于2 h)的无误码(误码率小于10-12)传输。
Abstract
Intra-channel four-wave mixing (IFWM) affects system performance in 160 Gb/s optical time division multiplexing (OTDM) communication systems. The effect of IFWM on the performance of a 160 Gb/s OTDM transmission system is analyzed. Strong dispersion management to suppress the detrimental effects of IFWM is theoretically presented and experimentally verified. The results show that amplitude fluctuation at "1" bit and ghost pulses at "0" bit are well suppressed by strong dispersion management in transmission link. The whole system performance is improved. Stable error-free (bit error rate less than 10-12) transmission over 107.6 km after more than 2 h is achieved without forward-error correction, and the power penalty is about 3.6 dB.
