Extinction Ratio and BER Estimation of a Three Degree ROADM Node with Different WSS Placement
Résumé
Introduction Reconfigurable Optical Add and Drop Multiplexers (ROADM) come into the sight of future network architecture and planning based on number of presented features which lead to optimized network utilization such as bandwidth allocation efficiency and routing flexibility. Moreover ROADMs are seen to be a key element improving current state of the optical networks by presenting dynamic provisioning and restoration techniques [1]. ROADMs are capable of enabling an advanced dynamic power/gain control for each channel and enable the ...
