How do the wavelengths of visible and infrared light relate to the quality of light transmission signals?
What will be an ideal response?
Some wavelengths travel through optical fiber more efficiently than others. Light wavelength is measured in nanometers (nm). Visible light, in the range of 400-700 nm, does not travel through fiber-optic cable with enough efficiency for data transfer. Infrared light, in the range of 700-1600 nm, travels efficiently enough for data transmission. Optical communications occur at three ideal wavelengths or windows: 850 nm, 1300 nm, and 1550 nm. High-speed transmissions typically use the 1300-nm window.
