German Operator M-net Selects Harmonic's RF Overlay Solution for GPON Network

SUNNYVALE, Calif. — June 23, 2009 — Harmonic Inc. (NASDAQ: HLIT) today announced that M-net Telekommunikations GmbH, a broadband telecommunications service provider based in Munich, Germany, has deployed Harmonic's HFC solutions for its new Gigabit passive optical network (GPON). M-net's new fiber to the building/home (FTTB/FTTH) service offers customers a high-quality digital/analog TV service in addition to high-speed data connectivity. The full range of Harmonic's 1550 nm MAXLink™ optical transmitters and amplifiers was deployed as part of the M-net RF overlay project.

"Harmonic's optical transmission solution offers greater reliability, performance, and cost-effectiveness for our GPON architecture," said Norbert Erl, head of central planning for M-net. "The high output levels and multiple outputs available with the amplifiers in particular met our network design criteria. Harmonic's flexibility and reliability were other favorable factors that led to our selection of Harmonic for the HFC optical network piece of the new service deployment."

Two Harmonic partners were instrumental in the M-net deployment. Quative served as system integrator for the entire service deployment, and Normann Engineering GmbH was key in the planning and installation of the M-net optical transport network in Munich and other Bavarian cities.

"Our 1550 nm solutions are ideal for a variety of network architectures, including GPON FTTH networks," said Sunil Frida, director of HFC solutions and strategy for Harmonic Inc. "M-net's selection of our transmitters and amplifiers for this deployment underscores Harmonic's experience and strength in delivering high-quality optical access solutions gained over the past 20 years working with the world's leading cable service providers."

Harmonic's comprehensive portfolio of reliable and high-performance HFC transport solutions, deployed by cable operators around the world for fiber-deep and FTTH architectures, includes a range of 1310 and 1550 nm transmitters, amplifiers, and nodes.
