Abstract

12 channel X 2.5 Gb/s WDM signal with unequal channel spacing allocation are successfully transmitted over 540 km of dispersion-shifted fiber through ten cascaded add/drop multiplexing (ADM) nodes consisting of arrayed-waveguide-grating (AWG). This paper describes a WDM add/drop multiplexing/transmission experiment employing the cascaded ADM nodes over 540 km of dispersion-shifted fiber without intentional dispersion management. The frequency detuning tolerance of the lightwave sources in the network with the cascaded ADM nodes is also discussed.
