Severe timing-jitter penalty caused by finite pump linewidth in transmission systems using dispersion compensation via mid-span spectral inversion

The authors show, for the first time, that pump linewidth can cause severe timing jitter penalties in transmission systems using dispersion compensation via mid-span spectral inversion (MSSI). A theoretical study of MSSI in 40 Gbit/s transmission systems is presented, and simple analytic formulas relating the pump linewidth to the transmission penalty are derived.
