All-optical regenerator

All-optical regenerator

A received signal (PMS) is combined with a first and a second pump signal (PS1,PS2) and fed into a highly nonlinear fiber (2). Nonlinear effects like SPM, XPM and FWM are used to reduce the signal distortion in the highly nonlinear fiber (2). The signal quality is substantially improved. The pump fr...

Zusammenfassung:A received signal (PMS) is combined with a first and a second pump signal (PS1,PS2) and fed into a highly nonlinear fiber (2). Nonlinear effects like SPM, XPM and FWM are used to reduce the signal distortion in the highly nonlinear fiber (2). The signal quality is substantially improved. The pump frequencies are allocated on both sides of the carrier frequency of the received signal. Suitable for all optical regeneration of phase modulated signals, such as PSK and DPSK signals.
