Abstract

Research on the all-photonics metro/access network is active as the next generation communication system. It aims to provide high-throughput, low-latency, low-power-consumption connections via end-to-end optical paths that directly link users without o/e/o conversion. One issue with realizing this network is how to implement the remote-control channel cost-effectively. In this work, we propose a cost-effective control signal transmission system based on auxiliary management and control channel (AMCC) and wavelength division multiplexing (WDM) technology. 25-Gbit/s non-return-to-zero (NRZ) 40 km transmission confirms the feasibility of the proposed system. The experiment comprehensively examines the influence that upstream/downstream control signals and main signals on different paths have on each other's receiver sensitivity. With the appropriate parameters, the penalty on the main signal's receiver sensitivity due to upstream/downstream control signals can be reduced to just 0.5 dB. The proposed method can realize cost-effective control channels in the all-photonics metro/access network with minimal sensitivity degradation.

同时接收波长多路复用控制信号和主信号的全光子城域网/接入网可扩展性研究

作为下一代通信系统，全光子城域/接入网的研究十分活跃。其目的是通过端到端光通路提供高吞吐量、低延迟、低功耗的连接，直接连接用户而无需进行o/e/o转换。实现这一网络的一个问题是如何经济高效地实现遥控信道。在这项工作中，我们提出了一种基于辅助管理与控制信道（AMCC）和波分复用（WDM）技术的经济高效的控制信号传输系统。25-Gbit/s 非归零（NRZ）40 公里传输证实了所提系统的可行性。实验全面考察了不同路径上的上行/下行控制信号和主信号对彼此接收灵敏度的影响。在参数适当的情况下，上行/下行控制信号对主信号接收灵敏度的影响可降至 0.5 dB。所提出的方法可以在全光子城域/接入网络中实现具有成本效益的控制信道，同时将灵敏度降低到最低程度。
