Increased bandwidth capacity per fiber delivers expansion of narrowcast services for cable operators 

CableNET® 2009, D.C. – April 1, 2009 – Aurora Networks, the only optical transport solution provider focused on delivering a cost-effective, optimized platform for next-generation cable services, today announced the availability of the industry’s first eight wavelength LcWDM® system. Delivering increased bandwidth capacity per fiber, Aurora Networks’ unprecedented eight wavelength ‘O’-band WDM solution enables cable MSOs to increase revenue-generating narrowcast capacity for services including HDTV, VoIP, Video on Demand (VoD) and high-speed data (HSD), without the need for major fiber construction.

Aurora Networks’ new LcWDM solution adds seventh and eighth wavelengths that can be combined with its full range of passive components on a single fiber from the existing node to a new node. With this solution, MSOs can cost-effectively drive fiber deeper into the network by subdividing their larger node service areas into eight separate service areas. With the transport of the eight wavelengths in the 1310 nm window, cable operators are free to utilize CWDM and DWDM technologies to add another 12 or more wavelengths.

“Today’s MSOs are challenged with cost-effectively meeting explosive consumer demand for targeted services,” said Wim Mostert, director of product management for Aurora Networks. “Aurora Networks continues to create a future-proof platform with the eight wavelength LcWDM specifically designed as a backwards-compatible solution for MSOs to increase their service offering.”

Aurora Networks’ LcWDM solution includes a full range of passive components for both headend and field deployment, including Aurora Networks’ new series of OP93D LcWDM field-hardened demultiplexers that support full service area segmentation. As part of the eight wavelength LcWDM system, OP93D demultiplexers can be installed in Aurora Networks’ nodes or splice enclosures to increase bandwidth.  The OP93D passive components add the following features to the LcWDM system:

• Standard demultiplexer with a cascade port for a downstream node

• Local return filter/combiner to enable 4X4 node segmentation on a single fiber

• Combiner to enable inclusion of downstream node’s return on the same fiber

One fiber can now carry both the upstream and the downstream traffic; previously, cable operators had to dedicate two fibers to this task.

There are currently more than 2,000 links deployed with Aurora Networks’ LcWDM solution.  Additional information, including technical product details and visuals for Aurora Networks’ LcWDM transmitter, can be found at www.aurora.com.
