Communication Optical Cable Coefficient
Optical losses of a fiber are usually expressed in decibels per kilometer (dB/km). The expression is called the fiber's attenuation coefficient α and the expression is where P (z) is the optical power at a position z from the origin, P (0) is the power at the origin. Limit met by doping titanium in fused core and pure fused Silica in cladding [Appl. This absorption occurs at discrete wavelengths, determined by the elements absorbing the light.
