摘　　要：全业务竞争压力使得运营商迫切需要实现网络的FMC(固移融合)。中国联通在ITU-T推动G.metro建议,以应对接入域FMC面临的带宽、生存性和成本等挑战。针对G.metro需求,提出一种具有自愈功能的新型WDM(波分复用)接入环,并进行了性能和生存性验证。结果表明,该接入环成本低、可靠性高。Telecom carriers in intense competitions urgently require full service solutions to Fixed-Mobile Convergence (FMC) networks.China Unicom promotes G.metro proposal in ITU-T to cope with the challenges that FMC faces in the assess do-main,such as bandwidth,survivability and cost.In view of such requirements,this paper proposes a novel WDM access ring with the self-healing function for G.metro and verifies its performances and survivability.The results indicate that this access ring is highly reliable and low in cost,suitable for FMC.
