Raman amplification / ˈrɑːmən / is a way of increasing the signal strength in an optical fiber. It is often used in a fiber that carries a signal for a long distance (such as in an undersea cable).

The most common types are: Discrete Raman Amplifiers: These amplifiers use a dedicated fiber spool to amplify the signal. They offer high gain and low noise figure but require a separate pump source.

Our work is based on the loop configuration in which only the anti-Stokes intensity is captured and processed to determine the temperature, thereby providing a self-calibrated solution
