Abstract:
1. A method for reducing timing jitter in transmission of Return-to-Zero modulated pulses comprising the steps of: measuring a total dispersion of a transmission fiber link; computing an optimal amount of pre-chirp to be added at an input of said transmission fiber link, wherein the optimal amount of pre-chirp to be added to the input of the transmission fiber is a function of the total dispersion of said transmission fiber link and a portion of fiber length having dispersion precompensated for at a transmitter side of the transmission fiber link; computing an optimal amount of pre-chirp to be added at an output of said transmission fiber link, wherein the optimal amount of pre-chirp to be added to the output of the transmission fiber is a function of the total dispersion of said transmission fiber link and a portion of fiber length having dispersion precompensated for at the transmitter side; adding said optimal amount of pre-chirp to said input of said transmission fiber link; and adding said optimal amount of pre-chirp to said output of said transmission fiber link.
