We experimentally demonstrate a 2,160×2,160 optical circuit switch with a switching time of less than 500 μs, aiming at fast and non-hierarchical intra-datacenter interconnection. The switch comprises delivery-and-coupling switches and wavelength-routing switches based on AWGs. We implemented twin 1×135 AWGs on a monolithic PLC chip.
Intra-data-center traffic is estimated to be about four times global Internet traffic and is continuously increasing. Applying optical switching to data center networks will increase network bandwidth and reduce power consumption while meeting the traffic requirements. One of the major attributes of the optical switch must be scalability. The wavelength routing switch is a promising technology for...
We propose an optical waveband and electrical OTN hybrid-HOXC node configuration, and a suitable network design algorithm. The proposed hybrid-HOXC network is verified as being very cost effective over a wide range of parameter values.
In this paper, we present a hybrid-hierarchical optical cross-connect (hybrid-HOXC) architecture that employs a waveband cross-connect for adding/dropping or routing waveband paths and an electrical cross-connect to grooming wavelength paths. Then, we have proposed a heuristic design algorithm for the hybrid-HOXCs based optical path networks. Its effectiveness is evaluated through numerical experiments...
We propose an efficient network architecture to implement optical fast circuit switching. To effectively manage dynamic path operations, we introduce a hierarchical structure consisting of physical network level and optical path level. Numerical experiments show that the proposed hierarchical network greatly reduces the necessary number of switch ports.
