Carrier frequency hopping for optical pulse transmission in dispersion-managed fiber systems

摘要

We present a fiber transmission system combining dispersion management with periodical hopping of channel frequencies by means of wavelength converters. We show that the signal distortion arising from chirp reversal may be substantially suppressed for optimized dispersion-managed links. We exemplify some potentialities of all-optical frequency conversion to limit the third-order dispersion impairments and timing jitter in long-haul fiber systems based on chirped RZ modulation format.
