Reconfigurable optical add-drop multiplexer (ROADM) is a device or equipment used in dense wavelength division multiplexing (DWDM) systems. Its function is to dynamically add or drop the path through remote reconfiguration. Business wavelength. In other words, in the middle of the line, the wavelengths of upstream and downstream services can be assigned as needed to achieve flexible scheduling of services.

Reconfigurable optical add-drop multiplexers are widely used in optical fiber communication networks, including telecommunications networks, data communication networks, video surveillance networks, etc.
ROADM’s key features include:
