实现了42.8 Gbit/s 差分相移键控调制信号的三信道波分复用传输实验.传输链路为410 km的标准单模光纤,分为四个放大段,采用色散补偿光纤进行色散补偿和掺铒光纤放大器/分布式喇曼放大器混合放大方式.给出了差分相移键控信号及其解调后的信号在背对背和传输后的光谱和眼图(中路波长信号).在接收端使用单端检测,给出中路波长的差分相移键控信号背对背情况和传输后的误码率曲线,并与单信道传输时进行比较.经过传输后的中路信号的误码率可维持在1.0E-3左右.

The three-channel transmission of 42.8 Gbit/s nonreturn-to-zero differential phase-shift keying (NRZ-DPSK) signal is demonstrated.The 410 km transmission link consists of four spans using standard single-mode fiber (SSMF).The dispersion compensation fiber (DCF) and erbium-doped fiber amplifier/distributed raman amplifier (EDAF/DRA) hybrid amplification are used.Both optical power spectrum and eye diagrams of the DPSK signal are given in back-to-back configuration and after transmission (center channel).The curves of bit error rate (BER) of the center channel also is given,both in back-to-back configuration and after transmission,which is compared with the curve in single-channel transmission configuration.The BER of the DPSK signal of the center channel is 1.0E-3 after transmission using single-ended detection.
