Hello, everyone!

I'm happy to share your knowledge about the ROADM!

Definition

A Reconfigurable Optical Add-Drop Multiplexer (ROADM) is a device that can add, block, pass or redirect modulated infrared (IR) and visible light beams of various wavelengths in a fiber-optic network. ROADMs are used in systems that employ wavelength division multiplexing.

Application

A DWDM Node that is installed with WSS boards enables wavelengths to travel in multiple directions.

Useful article. in the first picture, "optical signals over different wavelength" shall be "... over the same wavelength" for defintion of contentionless ... ?

Dear friend!
For the RDOM-Contentionless, wavelengths of optical signals of different wavelengths and optical signals of the same wavelength can be added or dropped.
