Harmonic Inc. has expanded its PWRBlazer family of optical nodes with a new model designed to enhance last-mile cable network capacity and availability.

The PWRBlazer III, designed for installation and maintenance on a wall or in an enclosure, is tagged for the European cable market, a region that makes extensive use of street cabinets, the company said.

Harmonic added that the new node will accommodate the bandwidth requirements for services such as digital television, high-speed data, voice and video-on-demand.

"The segmentation and redundancy features, which enhance last-mile scalability and reliability, combined with a form factor that fits into a street cabinet, will appeal to European cable companies as well as other operators around the world," said Patrick Harshman, president of Harmonic's Broadband Access Network Division, in a statement. Harmonic said the PWRBlazer III is compatible with existing PWRBlazer modules.
