Group delay dispersion performance requirement for optical cross connects and add-drop multiplexers in ultralong-haul DWDM transport systems

Abstract

The system penalty of undesirable chromatic group delay dispersion in wavelength-selective optical cross connects (OXCs) and add-drop multiplexers (OADMs) is the critical design constraint for 10- and 40-Gb/s transparent ultralong-haul dense wavelength-division-multiplexing network systems. Although narrow-featured dispersion within the passband of OXCs and… (More)
