Survey of systems experiments demonstrating dispersion compensation technologies

Improvement of three-level code division multiplexing via dispersion mapping

“…Compared to their all-optical counterparts, electronic compensation increases flexibility and gives a new impetus to transparent optical networks for adaptive and dynamic handling in cases where the total accumulated dispersion is not known in advance [7] Since 1980, dispersion compensation fibers (DCFs) have been used for mapping and managing dispersion compensation in optical communications [8]. Although new dispersion-shifted fibers and dispersion-flattened fiber have been developed and implemented in some applications, they are still costly and require new fiber cable installment, which tends to increase the system cost [8,9]. The optimal dispersion map depends on data rate, modulation format and the length of system dispersion compensator on wavelength division multiplexing (WDM) system performance [9].…”

The optimal dispersion map depends on data rate, modulation format and the length of system dispersion compensator on wavelength division multiplexing (WDM) system performance [9]. As various lengths of DCF are required for comparing various dispersion conditions, experimental surveys on the dispersion map effects would be problematical [10,11].…”
