Dual Fiber OADM Applications

Explore dual fiber Optical Add-Drop Multiplexer (OADM) applications for point-to-point and ring networks. This guide details unidirectional and bi-directional configurations, with in-service upgrades, and outlines mux/demux operations for various channels. Discover how to implement middle-point services, protected and unprotected rings, and linear add/drop networks. It covers specific channel wavelengths (λ1 - λ8) and terminal equipment setups. Ideal for network engineers looking to enhance transport networks with effective fiber management solutions.
