OpVista, Inc. and Vtesse Networks announced that Vtesse has successfully completed a 40G trial deployment of OpVista's Dense Multi-Carrier technology. This trial demonstrates DMC technology's ability to enable service providers like Vtesse to incrementally upgrade their optical transport network capacity to support the growing crush of corporate storage and consumer driven video services without costly network re-engineering.

    As part of a strategic initiative to deliver new bandwidth services cost effectively, Vtesse deployed a DMC-generated 40G wavelength over an 860 km (534 mile) link on an in-service 10G-engineered optical network. DMC technology combines advanced multiple carrier photonics, lambda stabilization, and multi-level modulation to deliver 40G and 100G bandwidth per wavelength, while maintaining compatibility with the characteristics of today's 10G optical infrastructure.

    OpVista is a pioneer in applying Dense-Multi Carrier, Scalable-ROADM, and packet switching technology to solve the transport networking issues faced by leading service providers. The OpVista product family leverages innovative patented technologies to deliver state of the art Optical Transport Networking that enables our customers to provide bandwidth intensive services cost effectively to customers worldwide. Our solutions utilize technology to leverage the current fiber infrastructure investment by reducing the transport networks lifecycle costs, and enhancing service turn-up times.

    "As the leading specialist optical networking service provider to many of the UK's largest and most effective organizations, it is essential that we give our enterprise customers the ability to exploit the very latest in optical networking technologies to deliver continuous gigabit and terabit level connectivity affordably, reliably and securely," commented Aidan Paul, Chief Executive Officer, Vtesse Networks.

    Vtesse Networks specialises in removing the constraints that traditional telecoms services place on communications traffic between key sites. Whether the requirement is to interconnect buildings on a single campus or to interconnect data centres in different towns and cities, Vtesse Networks' goal is to make all sites appear to users, servers, storage, and applications as though they are in the same building.

    Aidan Paul went on saying: "Based on this trial, I can easily see how Vtesse can cost effectively maintain its industry leading network performance and meet existing customer demand for 40G services using OpVista's DMC-based system products. We are extremely impressed by OpVista's DMC technology and its ability to overlay new high-speed services on our existing infrastructure without any dispersion impairments."

    "Vtesse has a well earned reputation for operating one of the most advanced, high performance optical networks in Europe. This trial demonstrates how simple it is to use DMC technology enabled solutions to expand the service carrying capacity of existing 10G networks," stated Karl May, President and Chief Executive Officer, OpVista. "DMC technology gives service providers the capacity they need to deliver new, bandwidth-intensive services without requiring investment in re-building their installed 10G optical networks. With DMC technology, service providers worldwide can finally break free from the traditional cycle of major capital investments and "fork lift" upgrades to enable new revenue-generating services."
