WebMar 1, 2003 · An alternate solution is to transmit each optical signal on a different wavelength, known as wavelength division multiplexing (WDM). Figure 1. Comparison … WebThe three main wavelengths used for fiber optic transmission are 850, 1300, and 1550 nanometers. These wavelengths are used in fiber optics because they have the lowest attenuation of the fiber. The length of a wave has a direct relationship with its attenuation rate − the longer the wave, the less attenuation.
