摘　　要：基于PDM-QPSK(偏振复用-正交相位调制)以及相干光加高速DSP技术的100G传输技术在骨干网的应用越来越成熟。然而,此100G传输方案价格依然昂贵,当采用100G应用于底层网络,例如接入网以及数据中心交换机的互联互通时,价格成本考量就显得尤为突出。提出了一种新型的100G传输方案,以反向复用技术与多通道分发(MLD-Multi Lane Distribution)技术为基础并实现了基于此方案的样机设计,并且完成了48小时的160 km的无误码传输测试。实验证明,此方案基于传统单模光纤的100G传输性能良好,且是真正实现了低成本的100G传输方案。The coherent PM QPSK 100G technology is getting matured and rapidly deployed in telecom backbone network. Howev- er, the coherent and high speed DSP based 100G technology is still too much expensive, especially, when 100G goes to access net- work and data center switch inter-connection applications. A new 100G technology which is based on inverse-multiplexing tech- nology and MLD （Multiplex-lane Distribution） mechanism is proposed. We have prototyped this idea into a low cost and real 100G system, and successfully completed error free transmission over 48 hours through the conventional 160 km SM fiber using a standard 100GbE signal.
