Motorola intros CWDM for MSOs

JUNE 20, 2007 -- Motorola, Inc has introduced its Enhanced Coarse Wavelength Division Multiplexing (E-CWDM) technology at the Society of Cable and Telecommunications Engineers Cable-Tec Expo.

The E-CWDM technology is designed to increase downstream service delivery capacity over cable networks by transmitting multiple CWDM optical signals over a single fiber-optic connection, enabling operators to segment serving areas into three, four, or five discrete areas. With each optical signal carrying 1-GHz loading of broadcast and narrowcast content over distances up to 25 km between the hub and optical node, operators can cost-effectively meet the need for additional service capacity for HDTV, VoIP, VOD, and high-speed DOCSIS services, Motorola says.

Motorola asserts that E-CWDM is both economical and simple to deploy, with inherent system reliability that can endure harsh outside plant environments and changes in optical characteristics of components over time. By increasing bandwidth through greater segmentation, operators can raise overall voice, data, and video broadband throughput while avoiding the expense of adding new fiber. With its 25-km range, E-CWDM covers a vast majority of optical node locations, the company says. Motorola also claims its technology exceeds that of competitive CWDM offerings, which the company says typically offer up to two wavelengths and range limitation of around 12 km.

"Motorola's E-CWDM solution offers an economical approach and provides the performance needed for fiber deep applications over long distances -- and more than doubles the service delivery capacity of existing CDWM solutions," said Kevin Keefe, vice president of marketing, Motorola Home and Networks Mobility. "With this level of performance and range, along with the bandwidth potential, E-CWDM technology becomes a very attractive transport option. We expect this solution will be very appealing to cable operators as they look to expand capacity for bandwidth-intensive applications like high-definition video-on-demand, time-shifted television services and very-high-throughput broadband Internet."

Motorola's E-CWDM technology is utilized in the Motorola OmniStar GX2 optical transport platform and SG4000 optical node platform.
