OADM

C-LIHGHT OADM (Optical Add-Drop Multiplexer) is a critical component in optical communication networks, designed to selectively "add" or "drop" specific wavelength channels in wavelength-division multiplexing (WDM) systems without requiring full optical-to-electrical signal conversion. Utilizing technologies such as fiber Bragg gratings (FBGs), arrayed waveguide gratings (AWGs), or micro-ring resonators, OADMs filter or reflect targeted wavelengths to dynamically route specific channels at network nodes while allowing others to pass through. This enables flexible wavelength management, reduces reliance on electronic processing, lowers latency, and cuts costs. OADMs are widely deployed in metropolitan networks, backbone networks, and reconfigurable optical networks (e.g., ROADM), serving as a cornerstone for building efficient, adaptive, and intelligent optical infrastructures.
