Establishment and Performance Analysis of General Structural Models of Single-fiber Bidirectional WDM-PON with Star Topology and Ring Topology

摘要

In this paper, the general structural models of single-fiber bidirectional wavelength division multiplexing passive optical network with star topology and ring topology are proposed. The performances of the two general structural models including network scale, construction cost and system reliability, are analyzed and compared numerically. In particular, link failure and node failure are considered as two different types of failures and discussed separately in the context. The characteristics of the two models, which are concluded in the end of this paper, can be the guide in the deployment of WDM-PON.
