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.

This solution enables cable operators to leverage existing and future fiber investments, resulting in unparalleled service competitiveness, efficiency and cost-saving benefits.

Designed to introduce PON into existing RFoG environments, or vice versa, Aurora Networks’ VHub OR4168 module enables operators to extend network reach from 10 - 20 km to over 60 km using a single fiber to provide a local service area concentration point for management of both downstream and upstream RFoG and PON wavelengths. The module also facilitates route redundancy for high network reliability and increases VHub efficiency and cost savings by consolidating the functionality of three separate products.  This level of integration increases the physical space available within the VHub, enabling cable operators to add further modules to increase upstream and downstream capacity.

Aurora Networks’ new CP8013U RFoG CPE is a cost-effective, field-hardened device which supports today’s triple play service requirements for video, voice and data services including DOCSIS® 3.0 cable modem traffic. The new CPE fits within a compact die-cast housing that provides a rugged, RF-shielded environment for long-term stability and reliability, and is supplied with a power inserter. The CP8013U is supported by a full line of outdoor housings with optimized fiber management, standard and UPS powering options.

“Since 2006, cable operators have powered their RFoG deployments with Aurora Networks’ unique and innovative VHub products.  Our evolving cable solutions provide operators with the most efficient end-to-end FTTP solution on the market today,” said John Dahlquist, vice president of marketing at Aurora Networks. “Our complete RFPON solution not only serves as a way to extend capabilities in traditional RFoG situations, but is also a significant new tool for operators to address the largely untapped commercial services market.”

For years, cable operators have turned to Aurora Networks’ to deliver high-speed data services through initial deployments of either its RFoG solution, primarily serving residential customers, or GEPON solution, for commercial customers. Now, as service demands evolve, Aurora Networks’ fully-integrated, end-to-end RFPON architecture will maximize flexibility for cable operators deploying an FTTP network today, with virtually unlimited network reach over a single fiber supporting all current CPE devices, while having a direct migration path to accommodate the all-IP world of the future.

At CTIA Wireless 2009, Spirent is unveiling new Virtual Drive Test and Fading Lab functionality on Spirent’s SR5500 Wireless Channel Emulator, the award-winning solution for wireless receiver performance testing. 

Virtual Drive Test allows rapid re-creation of RF conditions to bring real-world field testing of mobile devices into the lab. Fading Lab enables the creation or replay of highly-detailed, advanced radio environments from a wide range of data sources.  

“Virtual Drive Test reduces the amount of physical field testing required in a product’s life cycle resulting in significant cost savings,” said Rob VanBrunt, vice president of Spirent’s CDMA and Physical Layer market segment. “It also offers some clear technical advantages over field testing, enabling the same precise scenario to be repeated across multiple test runs, eliminating much of the uncertainty inherent to field testing.” 

Virtual Drive Test uses Spirent’s exclusive Dynamic Environment Emulation (DEE) feature to provide a more rigorous and sustainable alternative. Virtual Drive Test generates a set of controlled dynamic RF channels based on channel parameter data. Complex radio mobility scenarios can be created without deploying scores of vans, and the RF environment remains consistent between test iterations. 

 Spirent’s new Fading Lab supplements the SR5500’s existing real-time engine with a new “Fading Data Playback” engine. The Fading Lab engine converts data into a sample-accurate wireless RF environment. The Fading Lab’s universal interface accepts data from a wide range of sources including channel-sounding tools and software packages. Virtually any mathematical or ray-tracing software package can be used to synthesize the input data, as can custom software packages or scripts. The text-based template allows the user to create any customized fading model imaginable. 

“For wireless operators and device manufacturers, the Spirent SR5500 has been there to eliminate the risk of missing a critical RF issue.” added VanBrunt. “Now Fading Lab’s flexibility eliminates the risk of running up against a channel model your equipment can’t address.” 

The Fading Lab includes Fading Studio, a software package that creates advanced channel scenarios for testing MIMO and other multiple-antenna systems. These already include Spatial Channel Models (SCMs/SCMEs), with models defined by the European Wireless World Initiative New Radio (WINNER) consortium to follow shortly. 

Demonstrations of the Spirent SR5500 and the company’s wide range of other wireless device, application and infrastructure testing solutions will be showcased at Booth #744 at CTIA Wireless 2009, April 1-3 in Las Vegas. For more information visit www.spirent.com/go/sr5500
