Webflow through the light source. The two types of optical sources are light-emitting diodes (LEDs) and laser diodes. The optical source launches the optical signal into the fiber. The optical signal will become progressively weakened and distorted because of scattering, absorption, and dispersion mechanisms in the fiber waveguides. WebFiber optic communication systems operate in the 850-nm, 1300-nm, and 1550-nm wavelength windows. Semiconductor sources are designed to operate at wavelengths that minimize optical fiber absorption and maximize system bandwidth fLED Wavelength 1.2399 ( m) E (eV) = hc/E (eV) = wavelength in microns H = Planks constant C = speed of light
