Abstract :
We propose a system for tuning with an electrical signal dispersion compensation over a broad range of transmission distances for different transmission bit rates. It is composed of chirped gratings and a phase modulator with an electrical modulation signal varying to achieve the tuning in the link length for which the dispersion is compensated. It is demonstrated that with fiber gratings and a phase modulator in the proposed configuration, a broader tuning range than with the prechirp technique is achieved. The influence of the fiber grating ripples in the system behavior is also considered
