TMCNet: Austria's HFC Network Opts for Harmonic's SUPRALink DWDM Transport Solution

[June 03, 2009]

Austria's HFC Network Opts for Harmonic's SUPRALink DWDM Transport Solution

Jun 02, 2009 (Close-Up Media via COMTEX) -- Harmonic Inc. announced that its SUPRALink 1550 nm dense wave division multiplexing (DWDM) transport solution has been selected by the province of Salzburg, Austria, for an upgrade to its HFC cable infrastructure.


The new deployment will be implemented by Normann Engineering GmbH, a longstanding Harmonic partner and reseller in the region.

Salzburg is in the process of segmenting the HFC network to increase bandwidth to the home for DOCSIS 3.0 data and video services. The company said the high performance SUPRALink transmitters and amplifiers-which significantly increase reach and eliminate the need for additional fiber and active devices in the network-offer Salzburg a very cost-effective and reliable solution. The full-band 1550 nm directly modulated system is the industry's first to support up to eight wavelengths at a distance of up to 40 km with optical amplification, for up to 1 GHz of both digital and analog content per wavelength.

"Harmonic has been providing Salzburg with reliable and high quality HFC optics for well over a decade," said Reinhold Ratzinger, CEO for Telecommunications, Salzburg AG. "The exciting new SUPRALink 1550 nm DWDM system makes it possible to significantly increase bandwidth without laying new fiber. This saves us a substantial amount of time and money, in addition to being a technically superior solution." "The distances involved and number of wavelengths needed for this upgrade required latest generation technology, since the limited reach of 1310 nm DWDM solutions posed technical challenges. Other solutions, such as externally modulated lasers or optical combining of broadcast and narrowcast signals, were operationally complex or cost prohibitive. The scalability and unique capabilities of Harmonic's SUPRALink solution provide Salzburg with a competitive advantage by enabling higher speed data services without a significant increase in capital expenditures," said Helmut Normann, CEO of Normann Engineering GmbH.

Harmonic's new SUPRALink technology enables cost-effective DWDM segmentation for the majority of installed HFC networks, and as a result significantly extends the capacity and longevity of existing HFC infrastructures.

"The SUPRALink solution is ideal for node segmentation, particularly in scenarios where operators have limited fiber availability. It utilizes advanced patent-pending technology to deliver up to a four-fold increase in fiber reach over 1310 nm DWDM or CWDM systems, overcoming limitations of alternative downstream solutions," said Nimrod Ben-Natan, Vice President of Product Marketing, Solutions and Strategy for Harmonic Inc.

Salzburg AG, in the province of Salzburg, is a provider for energy, telecom as well as transportation.

Normann Engineering GmbH is a company for offering products and services for broadband and broadcasting.
