Overview of 12 Channel CWDM

Coarse Wavelength Division Multiplexing (CWDM) is a technology that multiplexes multiple optical carrier signals on a single optical fiber by using different wavelengths (or colors) of laser light. This method allows for the transmission of multiple data streams simultaneously, significantly increasing the capacity of the fiber. A 12 Channel CWDM system expands this capability by supporting up to 12 different wavelengths, making it an efficient and cost-effective solution for modern optical networks.
