A system and method for reducing timing and amplitude jitter in
trnasmission of Retrun-to-Zero modulated pulses is described. In the
reduction of amplitude jitter the modulated pulses must be phase
coherent. The method comprises 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, computing an
optimal amount of pre-chirp to be added at an output of said transmission
fiber link, adding said optimal amount of pre-chirp to said input of said
tranmisssion fiber link and adding said optimal amount of pre-chirp to
said output of said tranmisssion fiber link. The system for reducing
timing jitter in transmission of Return-to-Zero modulated pulses
comprises means for measuring a total dispersion of a transmission fiber
link, means for computing an optimal amount of pre-chirp to be added at
an input of said transmission fiber link, means for computing an optimal
amount of pre-chirp to be added at an output of said transmission fiber
link, means for adding said optimal amount of pre-chirp to said input of
said transmission fiber link and means for adding said optimal amount of
pre-chirp to said output of said transmission fiber link.
