We propose a reconfigurable WDM multicast scheme supporting content delivery from origin servers to cache servers in CDN based on SOA and TB-WSS. One-to-six/seven/eight 10 Gb/s QPSK of reconfigurable WDM multicasts have been successfully demonstrated.
A simultaneous all-optical WDM multicast and unicast scheme with large bandwidth for WDM optical access network by using a multicast module based on FWM in SOA has been proposed and verified. Two strategies of setting the multicast module have been discussed to apply this scheme to passive optical network and active optical network. One-to-four WDM multicasts of 10Gb/s NRZ-OOK signal are successfully...
We not only propose three flexible optical cross-connect (OXC) structures, with the ability of wavelength-division multiplexing (WDM) multicast, but also experimentally demonstrate two WDM multicast schemes based on four-wave mixing in a semiconductor optical amplifier (SOA). One-to-ten WDM multicast of 25-Gb/s QPSK signals is achieved with three pumps, and the power penalties for all signals are...
