Q
The method for taking advantage of optical wavelength of transmission, in order to increase capacity of information in an optical transmission medium is known as __________
AA. Wavelength division multiplexing (wdm)
BB. Time division multiplexing (tdm)
CC. Frequency division multiplexing (fdm)
DD. Code division multiplexing (cdm)
Correct Answer:
A. A. Wavelength division multiplexing (wdm)
Explanation:
Wavelength Division Multiplexing (WDM) is a multiplexing technique that combines a number of optical signals into a single optical fiber. It combines wavelength of these different optical carrier signals and helps in increasing the capacity of optical fibers by decreasing the transmission loss.
