摘要

为了研究超高速大容量光传输系统关键技术

利用16路光源

每路光源采用相干光PDM（偏振复用）16QAM（16进制正交振幅调制）OFDM（正交频分复用）调制实现了单路传输速率为1.92Tbit/s、C波段总速率为30.7Tbit/s的80km普通单模光纤传输系统。每路光源信道包含了45路光子信道

其频谱宽度为250GHz

系统谱效率为7.68Gbit/s/Hz。所有信道经过80km传输后的误码率均低于第三代FEC（前向纠错）解码门限2×10-2。

Abstract

For the purpose of studying the key technologies for future ultra-high-rate large-capacity optical transmission systems

we realize a 16-superchannel WDM transmission of 1.92 Tbit/s/ch Polarization Division Multiplexed（PDM） 16QAM Orthogonal Frequency Division Multiplexing（OFDM）over 80 km SMMF

the total data rate of which is 30.7 Tbit/s in C band occupancy.Each superchannel consists of 45 subchannels with a spectral width of 250 GHz and a spectral efficiency of 7.68 Gbit/s/Hz.The BER of all channels after 80 km transmission is smaller than 2×10-2

the third generation FEC decoding limit.
