What kind of light source is used in optical cables

Optical fiber primarily uses infrared light, not visible light, due to lower signal attenuation. Common wavelengths are 1310nm and 1550nm, where silica glass fiber has minimal loss (as low as 0. Some inexpensive short-distance systems use LEDs that emit visible light, but most systems carry. The four main types of optical sources are LEDs, Fabry-Perot (FP) lasers, Distributed Feedback (DFB) lasers, and Vertical Cavity Surface-Emitting Lasers (VCSELs). All convert electrical signals into optical signals but differ in their designs and capabilities. As recommended by the ITU-T (G. 3), optical light sources are also used to. The basic building blocks of an optical-fibre link are the light source, the fibre and the detector (Figure 1).
