Time Warner Cable deploys OpVista's optical transport system in major regional network

May 3, 2004 Irvine, CA -- OpVista announced that its MetroVista 2000 WDM-based optical transport system has been deployed by Time Warner Cable at 12 sites in Waco, Texas and the surrounding region. MetroVista enables users to deliver digital video, high speed LAN and Internet data, voice, and legacy ATM on a single fiber pair.

"The network in Waco is a ideal venue for demonstrating the exceptional range of capabilities of the MetroVista product. This is a large scale, fully converged regional network carrying six different protocols supporting voice, data and video," said Ron Foster, OpVista's vice president of marketing and sales. "It clearly demonstrates how our customers can economically consolidate their VOD servers and all of their regional transport as well."

The converged network carries SONET rates OC-3/12/48, Gigabit Ethernet (GbE), ATM and DV6000 over a central ring network with subtending rings and optical protection. Supported services include internal LAN, TDM voice, IP data, video on demand, and legacy digital video.

The MetroVista optical system consolidates multiple formats and delivers up to 800 Gbits/sec on a single fiber. Because it is designed to International Telecommunications Union (ITU) standards, it works with legacy optical systems and provides an instant "patch-cord" upgrade to 10-Gbit/sec capacity. Distances up to 1,000 km require no dispersion compensation or signal regeneration.

MetroVista provides a reconfigurable and cost-effective architecture for wavelength management because all wavelengths are broadcast throughout the network and are available at all nodes. Reconfigurability is provided by R-OADMS, tunable receivers that remotely and instantaneously tune to the desired wavelength. As little as a single GbE can be dropped and optical power balancing is automatic, without disrupting existing traffic.
