抽象的。提出了一种灵活可重构的波分复用(WDM)组播方案，该方案通过半导体光放大器中基于四波混频(FWM)的组播模块(MM)支持下行紧急组播通信。它是处理突发、大带宽、实时组播业务的一种应急措施，具有服务提供速度快、资源利用率高的特点。在激光无效或调制器故障导致大数据迁移或网络灾难的情况下，它还可以起到物理备份的作用。在不改变WDM-OAN结构的情况下，为WDM-OAN提供方便可靠的组播服务和紧急保护。讨论了在光线路终端和远端节点设置MM的策略，将该方案分别应用于无源光网络和有源光网络。利用所提出的方案，我们进行了一个概念验证实验，在该实验中，两种策略下的1到6/8个10Gbps不归零差分移相键控WDM多播成功地在20.2公里的单模光纤上传输。通过该方案，可以实现一对多的可重构WDM组播，以处理更高数据速率和其他调制格式的组播业务。它可以应用于不同的WDM接入技术，如时分-波分复用-OAN和相干WDM-OAN，并顺利升级。
Abstract. We propose a flexible and reconfigurable wavelength-division multiplexing (WDM) multicast scheme supporting downstream emergency multicast communication for WDM optical access network (WDM-OAN) via a multicast module (MM) based on four-wave mixing (FWM) in a semiconductor optical amplifier. It serves as an emergency measure to dispose of the burst, large bandwidth, and real-time multicast service with fast service provisioning and high resource efficiency. It also plays the role of physical backup in cases of big data migration or network disaster caused by invalid lasers or modulator failures. It provides convenient and reliable multicast service and emergency protection for WDM-OAN without modifying WDM-OAN structure. The strategies of an MM setting at the optical line terminal and remote node are discussed to apply this scheme to passive optical networks and active optical networks, respectively. Utilizing the proposed scheme, we demonstrate a proof-of-concept experiment in which one-to-six/eight 10-Gbps nonreturn-to-zero-differential phase-shift keying WDM multicasts in both strategies are successfully transmitted over single-mode fiber of 20.2 km. One-to-many reconfigurable WDM multicasts dealing with higher data rate and other modulation formats of multicast service are possible through the proposed scheme. It can be applied to different WDM access technologies, e.g., time-wavelength-division multiplexing-OAN and coherent WDM-OAN, and upgraded smoothly.
