Reflection loss

From Wikipedia, the free encyclopedia

In telecommunications, reflection loss is one of:

1. At a discontinuity or impedance mismatch, e.g. in a transmission line, the ratio of the incident power to the reflected power. Reflection loss is usually expressed in dB.
2. In an optical fiber, the loss that takes place at any discontinuity of refractive index, especially at an air-glass interface such as a fiber endface, at which a fraction of the optical signal is reflected back toward the source. This reflection phenomenon is also called "Fresnel reflection loss," or simply "Fresnel loss."

Bold textReflection Loss

Transmition loss of a line which inturn results in part of the energy being reflected back the the source.
