Today, Harmonic introduced a new dense wavelength division multiplexing (DWDM) transmission platform that it said will help cable operators extend the reach of their existing fiber-optical networks.

Harmonic said the new DWDM transmission system, which is called the SupraLink 1550 NM, can deliver up to a fourfold increase in fiber reach over 1310 NM systems by using its patent-pending technology.

Sunnyvale, Calif.-based Harmonic said SupraLink is the industry's first system to support up to eight wavelengths per single fiber over link distances of 40 km with optical amplification and 25 km without optical amplification, for up to 1 GHz of both digital and analog content per wavelength.

The platform helps operators to minimize their capital expenditures when segmenting their networks and overcomes limitations in fiber reach and wavelength scalability of alternative downstream coarse wavelength division multiplexing (CWDM) and 1310 nm DWDM solutions.

"Harmonic's SupraLink system will allow service providers to deploy optical nodes deeper in the network while minimizing the cost of constructing new fiber routes," said Nimrod Ben-Natan, vice president of product marketing, solutions and strategy for Harmonic.
