A Highly-Reliable Long-Reach WDM Access Network with Broadcasting Services and Flexible Scalability

摘要

In this paper, a novel wavelength division multiplexing (WDM) access network has been proposed. Here, the optical protection modules (OPMs) and erbium-doped optical fiber amplifiers (EDFAs) employed in both the central office (CO) and the remote node (RN) enable this WDM access network with broadcasting services not only to achieve high reliability under long-distance transmission but also to scale up easily in the future. Also, this scheme has the feature of Rayleigh Backscattering mitigation. The analysis shows good performance of this network.
