What is the difference between WDM and OTN?
Feb 17 , 2023
WDM and OTN are two different communication technologies, the differences are as follows: WDM (Wavelength Division Multiplexing): WDM is an optical transmission technology that uses optical signals of different wavelengths to multiplex multiple data streams on one optical fiber to increase the transmission capacity of the optical fiber. WDM technology combines optical signals of different waveleng...

WDM filter plays a very important role in DWDM system
Apr 11 , 2023
A WDM (Wavelength Division Multiplexing) filter is a common optical device that can be used to separate and combine optical signals of different wavelengths. In optical fiber communication, WDM filters are widely used in DWDM (Dense Wavelength Division Multiplexing) systems for multiplexing and demultiplexing. The working principle of WDM filters is based on the principle of optical interference. ...
