40 Channel 100GHz Flat Type AAWG WDM

How does WDM work?

Wavelength × frequency = speed of light (constant value), so wavelength division multiplexing is actually frequency division multiplexing
To put it simply, we can also think of WDM as a highway-different types of vehicles flood into this highway, and then split after reaching the destination.
The role of WDM is to increase the transmission capacity of optical fiber and improve the utilization efficiency of optical fiber resources.
For a WDM system, if you want it to work normally, you obviously need to control the wavelength (frequency) of each optical signal. If the wavelength interval is too short, it is easy to "crash". If the wavelength interval is too long, the utilization rate is very low.

Athermal AWG WDM, also known as Athermal Arrayed Waveguide Grating WDM and AAWG WDM Splitter, along with FBT WDM splitter, LAN WDM splitter, Filter WDM splitter, dense WDM splitter and coarse WDM splitter, are the most commonly used WDM device in construction of PON.
