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。
100G transmission technology based on PDM-QPSK (Polarization Multiplexing-Quadrature Phase Modulation) and coherent light plus high-speed DSP technology is becoming more and more mature in the backbone network. However, the price of this 100G transmission solution is still prohibitively expensive. Considering price costing when adopting 100G for interconnection of underlying networks such as access networks and data center switches, A new 100G transmission scheme is proposed based on the MLD-Multi Lane Distribution (DRM) technology and the prototype design based on this scheme is completed. The 48-hour 160 km Code transmission test. Experiments show that this scheme is based on the traditional single-mode fiber 100G transmission performance is good, and is truly low-cost 100G transmission scheme.
