Answer :
Answer :
- Wavelength division multiplexing
The scheme of combining a number of wavelength over a single fiber called wavelength division multiplexing. In this techniques fiber optic transmission using multiple light wavelength to send the data over the same medium or device. In fiber optic, two or more wavelength (colors) of light can travel on one fiber and several signal can be transmitted in optical wave guide at differing wavelengths.
