This work examines protection of multicast sessions in optical networks utilizing a novel segment-based algorithm called Level Protection. Our proposed scheme exhibits improved performance compared to...
We experimentally demonstrate a dynamic λ-OFDMA with selective DPSK overlaid,and multicast control is realized through an alternative LO. The 10-Gb/s P2P signal, 2.5-Gb/s overlaid and 1.25-Gb/s upstre...
By combining XGM, and cascaded FWM effects in an SOA, seven multicast channels with 100-GHz spacing are demonstrated using single pump laser source. The power penalty of these multicast channels is le...
Transmission of selective multicast services has been demonstrated in a cost-effective dynamic channel allocation router. The approach envisions heterogeneous infrastructures with unicast, broadcast a...
We propose and demonstrate optical multicast overlay on WDM-PON employing bandwidth efficient Inverse-RZ-duobinary signal. Multicast overlay control is realized by tuning the bias at the point-to-poin...
We investigate the problem of designing and engineering metropolitan area optical networks for the provisioning of multicast sessions. The Q-factor for each session is taken into account, aiming at ma...
We experimentally demonstrate a novel WDM-OFDM-PON architecture with centralized lightwave sources and PolSK multicast overlay. The 10Gb/s P2P signals, 2.5Gb/s multicast signals and 2.5Gb/s upstream s...
A WDM-PON with simultaneous delivery of 10-Gb/s downstream unicast and upstream data as well as 10-Gb/s multicast data is proposed. Downstream multicast data is superimposed onto the subcarrier genera...
We formulate and investigate the multicast tree protection in WDM optical networks with scheduled traffic. By optimizing the network resources jointly in space and time, survivable multicast sessions ...
We propose a novel WDM-PON broadcast/multicast architecture that superimposes inverse-RZ signal onto NRZ unicast signal. Multicast control is realized through extinction ratio adjustment of the NRZ si...
We propose a novel multicast tree construction algorithm for video distribution/multicasting. The algorithm successfully handles the optical signal impairments caused by transmission and branching, an...
