Reconfigurable optical cross-connect using WDM MUX/DEMUX pair and tunable fibre Bragg gratings

A reconfigurable 2/spl times/2 optical cross-connect (OXC) based on a WDM MUX/DEMUX pair and tunable fibre Bragg gratings (FBGs) is proposed. It has the advantage of uniform insertion loss and a reduction of the number of MUX/DEMUXs required. The cross-connect operation of the proposed OXC in the optical spectra domain has been experimentally demonstrated.
