Optical transmission system with stimulated Raman scattering amplification and gain equalization

摘要

The fibre optic transmission system has a transmitter (1) and receiver (3) with two signals (S1,S2) at different frequencies. A fibre optic line (2) and a pump (6) send a pump signal (Sp) to amplify along a structured Raman diffuser (4). Gain equalisation (5) is carried out to amplify each signal equally.
