TOKYO, June 8, 2010 /PRNewswire/ -- NTT Communications (NTT Com), Infinera Japan and Ixia Communications K.K. jointly announced on June 8 that they will provide a 100 Gbps Ethernet transmission network for practical operation, the world's first, during the Interop Tokyo 2010 trade show at the Makuhari Messe exhibition complex near Tokyo from June 9 to 11.

The 100 Gbps Ethernet network was proven in recent interconnection field tests and now will serve as the backbone network, named ShowNet, for Internet access by exhibitors and visitors alike during Interop Tokyo 2010.

ShowNet, one of the world's largest networks created for demonstration purposes, will showcase state-of-the-art network architecture for the interconnection of numerous types of devices and services.

The network comprises telecommunication and network infrastructure constructed and managed by NTT Com, an Infinera DTN(TM) scalable, large-capacity switched DWDM (dense wavelength-division multiplexing) system from Infinera, and a high-quality, customizable network tester for network systems and devices from Ixia, a leading maker of IP network testers.

ShowNet incorporates the Ethernet specification 100GBASE-LR4, which is scheduled to be standardized by mid-June after extensive testing to prove network throughput, latency and fluctuation. Interconnection of numerous devices using the 100GBASE-LR4 specification during the show will demonstrate the exciting possibilities of forthcoming next-generation on network technology.

Current Ethernet networks for Internet traffic and data communication are designed for speeds of up to 10 Gbps. Cumulative data volume carried over telecom backbones and worldwide interconnections, however, already surpasses hundreds of Gbps. A technology that bundles 10 Gbps networks is now being utilized for large-data transfers, but inherently faster transmission is required in view of growing data volume and needs for greater transmission efficiency and more enhanced network management.

Ethernet networks operating at 100 Gbps, which enables 25GB of data - the volume of a Blu-ray disk - to be transferred in two seconds at the theoretical maximum speed, are expected to lead to an explosive increase in broadband use.

Based on ShowNet's performance and user reactions during Interop Tokyo 2010, the three companies will consider taking accelerated steps to offer 100 Gbps Ethernet solutions in the foreseeable future, possibly including NTT Com's introduction of a 100 Gbps Ethernet communication platform for GIGA STREAM high-quality leased lines; Infinera's introduction of 100Gbps systems based on next-generation 500Gbps photonic integrated circuits and coherent transmission and Ixia's launch of the K2 for testing 40 Gbps and 100 Gbps devices based on the new IEEE802.3ba standard.
