Example text

Single mode fiber supports two orthogonal polarizations of the original transmitted signal. Random variations in the refractive index along with non-circularity of the core leads to the two polarized modes travelling with different velocities and hence spreading out in time. The effect is length related and will affect high bit rate signals more as the time frame between bits will be subsequently shorter and therefore more susceptible to interference from the trailing polarized mode. Analogue video signals will also suffer interference in the same way.

The calculation and measurement of light acceptance can be complex but its basic concepts are relatively straightforward to understand. Logically the amount of light accepted into a given fiber must be a function of the quantity of light incident on the surface area of the core for a given light source; otherwise, identical fibers will accept light in direct proportion to their core cross-sectional area. 8 23 Light acceptance and numerical aperture Equally important is the impact of numerical aperture.

Any pure material has an atomic structure which will absorb selective wavelengths of electromagnetic radiation. It is virtually impossible to manufacture totally pure materials and the absorption spectrum of any impurities serves to modify that of the pure material. Finally in the interest of certain applications it is necessary and desirable to introduce further modifying agents or dopants to improve the performance of the optical core. Most optical fiber is manufactured using a base of pure silica (silicon dioxide – SiO2) which is doped with germanium and other materials to create an effective core structure.
