摘要 全部利用线性啁啾光纤布拉格光栅(CBG)作色散补偿模块,在G.652光纤上实现2500km—10Gbps的超长距离无电中继传输系统。在2060km处,功率代价~2dBm(NRZ码,BER:10^-12,PRBS:10^23-1);在2530km处,较大功率代价下实现无误码传输,远超过相同条件下用色散补偿光纤(DCF)作色散补偿模块的传输系统的无误码传输距离。 Using dispersion compensation chirped Fiber Bragg Grating (CBG), 2500km-10Gbps transmission system on G.652 fiber is successfully demonstrated without electric regenerator. The CBG has the perfect performance: The group delay ripple is small (about±15ps), the group delay is large(about 2600ps/nm), and the insertion loss is low (only 4dBm). The system has 12 wavelength channels. The channel space is 0.8 nm (100 GHz), according to the wavelength standard (in C band) of the ITU- T suggestion. At 2060km in the system, power penalty is about 2dBm (condition: NRZ, BER=10^12, PRBS=10^23-1); At 2530km, Bit Error Ratio (BER) is free with high power penalty. However, the result is superior to the system using Dispersion Compensation Fiber (DCF) under the same condition.
