Wavelength Division Multiplexing is a technique that allows multiple frequencies (or wavelengths) to be transmitted over the same fiber simultaneously. This is accomplished by the use of optical transmitters or transceivers with outputs tuned to individual and specific wavelengths so that there are distinct and non-overlapping transmission channels.
Dense Wavelength Division Multiplexing (DWDM) takes WDM to the next level by decreasing channel spacing to 0.8nm or less and shrinking the operational wavelength range. This can produce 80 or more channels or lanes of traffic, opening the door to more high speed, high bandwidth applications.
Amazingly, all DWDM wavelengths reside within the narrow 1525nm to 1565nm region known as the C-Band. This area is utilized due to the relatively low (0.25dB/km) signal loss (fiber attenuation) compared to lower wavelengths found in the O or E-bands for example. As a result of the narrow channel spacing higher-precision lasers and filtering processes are required to maintain channel integrity and minimize interference.
