  • Wavelength Service In Optical Transport Networks
    By: Paul Ngai | - Optical WDM (Wavelength Division Multiplexing) networks are networks that deploy optical WDM fiber links where each fiber link carries multiple wavelength channels. An All Optical Network (AON) is an optical WDM network which provides end-to-end optical paths by using all optical nodes that allow optical signal to stay in optical domain without conversion to electrical signal. AONs are usually optical circuit-switched networks where circuits are switched by intermediate nodes in the granularity ...
