摘　　要：实验完成了42.8 Gb/s差分相移键控(DPSK)信号和9.95 Gb/s开关键控(OOK)信号的混合传输。光纤链路总长410 km,由四个放大段组成。每个放大段由标准单模光纤(SSMF)和色散补偿光纤(DCF)构成,采用掺铒光纤放大器/分布式拉曼放大器(EDFA/DRA)混合放大,42.8 Gb/s DPSK信号采用单端检测。给出了差分相移键控信号与开关键控信号分别在单路和混合传输410 km后的眼图光谱图以及误码率曲线。The hybrid transmission of 42.8 Gb/s differential phase shift keying（DPSK） and of 9.95 Gb/s on-off keying （OOK） signals is experimentally demonstrated.The length of fiber loop is 410 km.The transmission line consists of four spans,each including standard single-mode fiber（SSMF） and dispersion compensation fiber（DCF）.The signals are amplified by both erbium-doped fiber amplifier（EDFA） and distributed raman amplifier（DRA）.The 42.8 Gb/s DPSK signals is detected by single-ended detection.The optical power spectrum,eye diagram and the curve of bit error rate（BER） are given,both in single-channel transmission 410 km and in hybrid transmission 410 km.
