Intrinsic Attenuation
Intrinsic attenuation happens due to absorption and scattering.
- Absorption – It happens due to the imperfections in the optical fiber. It is caused by the atomic defects in the glass components. When light passes through fiber it may be absorbed by one or more components of glass. Absorption loss can happen from transition metal element impurities. This loss value is generally 0.4 dB/km at 1310nm and 0.25 dB/km at 1550nm.
- Scattering – It happens due to fiber materials and structural imperfections. Fiber structures have regions of high and low molecular density. Also several oxides present in glass leads to compositional fluctuations. This scattering of lights lead to loss of power or attenuation. Rayleigh scattering arises from variation in the density of fiber materials leading to random fluctuations.
Attenuation
In this article, we will be discussing about attenuation. We will also discuss about attenuation in optical fiber and networking. We will look into the various factors that causes attenuation in optical fiber and networking. We will discuss about attenuation coefficient. We also will discuss how can we measure attenuation and the methods that are available to measure. In addition to this, we will discuss how can attenuation be prevented. We will also compare attenuation with amplification and see their differences. Later in this article, we will discuss about the various advantages, disadvantages and application of attenuation.
