Characterization of optical add drop multiplexers in high bit rate WDM networks
Characterization of optical add drop multiplexers in high bit rate WDM networks
Characterization of Optical Add Drop Multiplexers (OADMs) in High Bit Rate Wavelength Division Multiplexing (WDM) systems is presented using theoretical systems simulations. Firstly the interferometric full-coupler based OADM is modelled in various configurations using coupled mode theory. Implications of the inherent non-optimum overall performance of this device in conjunction with additional system issues like filter misalignments and cascading are analysed. Filters with typical degraded spectral characteristics in the Drop or Add action exhibits at least 0.15 dB higher Eye Opening Penalty (EOP) compared to filter with optimized flat spectral response. For this kind of OADMs we found also that the Intra-Band dispersion EOP performance in a cascaded 'Add-and-Drop operation' - in a single-wavelength-processing-node - for a specific OADM is insensitive to the arrangement of the Bragg grating in the coupler waist and consequently to the individual spectral characteristics of the Add or Drop actions.

Abstract
Characterization of Optical Add Drop Multiplexers (OADMs) in High Bit Rate Wavelength Division Multiplexing (WDM) systems is presented using theoretical systems simulations. Firstly the interferometric full-coupler based OADM is modelled in various configurations using coupled mode theory. Implications of the inherent non-optimum overall performance of this device in conjunction with additional system issues like filter misalignments and cascading are analysed. Filters with typical degraded spectral characteristics in the Drop or Add action exhibits at least 0.15 dB higher Eye Opening Penalty (EOP) compared to filter with optimized flat spectral response. For this kind of OADMs we found also that the Intra-Band dispersion EOP performance in a cascaded 'Add-and-Drop operation' - in a single-wavelength-processing-node - for a specific OADM is insensitive to the arrangement of the Bragg grating in the coupler waist and consequently to the individual spectral characteristics of the Add or Drop actions.
