HUNTSVILLE, Ala. -- ADTRAN, Inc., (NASDAQ:ADTN), a leading provider of next-generation open networking and subscriber experience solutions, today announced that its Total Access 5000 (TA 5000) platform has been deployed to improve the reliability and resiliency of a leading regional utility's high-density Smart Grid power grid distribution network. A first deployment of its kind, the utility is leveraging the TA 5000 fiber access platform in targeted service areas as the enhanced communications system to its automated switching devices.

The ADTRAN network that has been deployed is a secure, high-speed, low-latency communication system that operates between power line reclosers without having to take the traffic through any equipment upstream of the OLT. It allows all automated line switching devices to employ ultra-fast and effective peer-to-peer coordination between other switching devices via GOOSE messaging utilizing the 61850 communication protocol, as well as enhanced high-speed wired SCADA communications. This allows for a larger and more complex centralized self-healing network.

"PON and 10G PON are creating opportunities to develop market-specific applications where communication between machines and devices is time sensitive. The utility market is just the tip of the iceberg," Ovum Principal Analyst Julie Kunstler said. "10G PON's fiber-based architecture with latency, capacity and security advantages, supports high-performance applications, such as the Smart Utility model."
