Method for nulling nonrandom timing jitter in soliton transmission.
The shift in pulse arrival times stemming from several important sources is not truly random but rather shows a high degree of correlation from one pulse to the next. Such jitter sources include the acoustic effect, solitons-soliton collisions in wavelength-division multiplexing, and the tendency of fiber birefringence to convert collision-induced polarization scattering into time shifts. Moving the acceptance window of a timedivision demultiplexer in approximate synchronism with the correlated time shifts effectively removes their potential for creating errors.
