摘要
对光的单边带归零信号(SSBRZ)的一种产生方式进行了推导.通过合理设置调制器的偏置电压,使产生的SSBRZ信号的一个边带得到更有效的抑制,而且没有引起光脉冲的变形.对其在普通单模光纤(SMF)40Gb/s传输系统中的传输进行了仿真,并和归零(RZ)信号、载波抑制的RZ(CSRZ)信号的性能相比较,结果表明:在色散完全补偿的单信道传输系统中,SSBRZ的抗非线性能力比RZ、CSRZ强·
A method to generate Single Sideband Return-to-Zero Signal(SSBRZ) is introduced by deriving formulas. One sideband of the generated SSBRZ signal is suppressed more effectively without distortion of the optical pulses. 40Gb/s single channel transmission of Return-to-Zero(RZ) signal, Carrier Suppressed Return-to-Zero(CSRZ) signal and SSBRZ signal over single mode fiber(SMF) are simulated. The results show that SSBRZ is superior to RZ and CSRZ against fiber nonlinearities when chromatic dispersion is completely compensated.
