What does CWDM do?
It allows different data streams to be transmitted simultaneously over a single optical fiber network.
How many channels does CWDM support?
Up to 18 wavelength channels.
At what OSI layer does CWDM work?
Layer 1 (physical).
How far apart are the different wavelengths of each CWDM channel?
20nm apart.
What are the two wavelength regions are most commonly associated with CWDM?
1310nm and 1550nm.
Which CWDM wavelength region is the most popular?
