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 a total of 18 channel wavelengths 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.
