Abstract

The management of chromatic dispersion is one of the challenges of emerging communication systems. Although chromatic dispersion helps minimizing the non-linear effects in DWDM systems, adequate management of this effect has to be performed. Dispersion Compensating Fibers (DCFs)¹ and Chirped Fiber Bragg Gratings (CFBGs)² are two well known solutions for compensating chromatic dispersion. DCFs are presently the preferred solution for simultaneous compensation of a large number of WDM channels. However, such a fiber is lossy and do not allow a proper compensation for all the WDM channels. Although the dispersion is properly compensated for one channel, the residual dispersion that exists at other channels can become significant and has to be compensated for after a certain propagation length.
