GCI Extends Network Capacity with Harmonic’s SUPRALink™ 1550 nm DWDM Solution

Harmonic Inc. (NASDAQ:HLIT) today announced that General Communication, Inc. (GCI), a provider of voice, video and data communication services to residential, commercial and government customers throughout Alaska, has deployed Harmonic’s SUPRALink™ 1550 nm DWDM transmission system and PWRBlazer™ segmentable nodes to expand bandwidth capacity across its network. Cable operators around the world are deploying Harmonic’s SUPRALink technology to cost-effectively increase fiber reach. GCI also utilizes Harmonic’s market-leading NSG™ edgeQAMs for its video-on-demand service.

GCI is transitioning from a centralized broadcast/narrowcast architecture with optical combining at the hubs to a distributed architecture using IP transport and full-band SUPRALink transmitters at the hubs for transport to the nodes. In addition to increasing bandwidth to the home, this approach improves reliability by eliminating single points of failure, simplifies node segmentation, and makes the network easier to troubleshoot.

“Harmonic’s HFC access and digital video solutions enhance the reliability, performance and efficiency of our cable network,” said Dave Smith, Project Manager at GCI. “Over the years, Harmonic has continued to provide innovative solutions for our HFC architecture. The SUPRALink system is a high quality solution that enables us to put in place a scalable, distributed fiber-deep architecture.”

Incorporating patent-pending technology, Harmonic’s SUPRALink solution cost-effectively delivers up to a four-fold increase in fiber reach over 1310 nm systems. SUPRALink is the industry’s first system to support up to eight wavelengths per single fiber over link distances of up to 40 km with optical amplification, for up to 1 GHz of both digital and analog content per wavelength.

“SUPRALink is being deployed by MSOs throughout North America and around the world,” said Sunil Frida, Director of HFC Solutions for Harmonic. “Its unique design increases fiber reach without requiring an increase in the number of fibers, freeing up fiber for commercial services or cell tower backhaul applications. This solution offers a clear savings in capital expenditures, and because it is an all-passive network, it provides a savings in operating costs as well for the cable operator.”

Harmonic’s full range of flexible fiber-based transmission solutions includes 1310 nm and 1550 nm CWDM/DWDM digital transport, scalable nodes and analog/digital return path systems. Using advanced technology that leverages the operator’s existing outside plant and minimizes operating costs, Harmonic’s fiber-deep and FTTH broadband network solutions deliver a wide range of services for leading cable operators around the world.
