CWDM full form

What is the full form of CWDM?

  • Coarse Wavelength Division Multiplexing

What does CWDM mean?

CWDM is a wavelength multiplexing technology for the city and also it accesses the network. Transmission is realized using total of 18 channels wavelength between 1270 nm and 1610 nm. Due to the channel spacing of around 20 nm, cost-effective lasers can be used. The channel width itself is 13 nm. The remaining 7 nm designed to secure the space to the next channel.
