Method and apparatus for chromatic dispersion compensation |
摘要 |
A method and apparatus is provided for managing chromatic dispersion in an NRZ-based WDM long-haul optical transmission system so that nonlinearities are reduced, especially those at the edge channels of the band. The method includes using between 500 ps/nm and 2000 ps/nm of residual dispersion and a 40%/60% pre/post DCU split ratio when the channel wavelengths are shorter than the zero dispersion wavelength. Using these dispersion compensation rules, the nonlinear propagation effects in NRZ-based WDM systems is reduced, thus allowing for higher optical power per channel and/or longer transmission distances.
