Abstract:
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 âˆ’z*optB2, where B2 is the total dispersion of said transmission fiber link, and z*opt denotes a portion of fiber length having dispersion pre-compensated for at the transmitter side of the 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 âˆ’(1âˆ’z*opt)B2; 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.
