What is Reconfigurable Optical Add-Drop Multiplexer

In the fiber optic network which uses wavelength division multiplexing (WDM), reconfigurable optical add-drop multiplexer (ROADM) is used to remotely add, block, pass or redirect modulated light emissions-infrared and visible-within a range of wavelengths. With ROADM devices, signal switching doesn’t … Continue reading
