Aurora Networks introduces 100-GHz DWDM Platform

June 11, 2004 Santa Clara, CA -- Aurora Networks will unveil a 100-GHz DWDM optical networking platform at Cable-Tec Expo, June 16-18, 2004, in Orlando, FL. The 40-channel transport system enables cable system operators to scale their networks to meet the demands of present and future services without the need to install additional fiber.

June 11, 2004 Santa Clara, CA -- Aurora Networks will unveil a 100-GHz DWDM optical networking platform at Cable-Tec Expo, June 16-18, 2004, in Orlando, FL. The 40-channel transport system enables cable system operators to scale their networks to meet the demands of present and future services without the need to install additional fiber.

"Every product in Aurora's DWDM line has been engineered to support 40-channel DWDM distribution without concerns for compatibility and interoperability," said Ron Wolfe, senior product Manager for Aurora Networks. "The rollout of this new platform allows our MSO customers to quickly and easily deploy high-bandwidth services over existing networks without costly fiber upgrades."

The Aurora 100-GHz DWDM optical networking platform comprises several products that mount in the Aurora universal chassis, as well as modules for Aurora's nodes. Aurora's patented universal chassis with its advanced backplane system significantly reduces optical interconnect cabling through the use of integrated multiplexing capabilities, the company says.

AT3510 Series Narrowcast DWDM Transmitters provide high output power (+10 dBm) from the Aurora universal chassis for long haul applications, and can overcome passive losses associated with optical broadcast narrowcast applications.

Mounted in the Aurora universal chassis, the DX3515 Series Digital Transponder converts any standard optical communications wavelength carrying digital signals from 155 Mbits/sec to 2.125 Gbits/sec to a 100-GHz spaced ITU wavelength to be fed over links up to 100 km with 40 optical channels per fiber.

The DT3515 Series Digital Transmitters digitize two RF carrier spectrums of either 42 MHz or 50 MHz and transmit the digital signal over a single output from the Aurora chassis on any of the 40 available wavelengths. These transmitters can be used for links up to 200 km, carrying up to 80 unique node returns on a single fiber.

The chassis-based OP3524 and node-mounted OP4538 Optiplex broadcast/narrowcast optical combiners enable management of broadcast and narrowcast service groups using a simple, all-optical process, for both hub sites and node enclosed "virtual hub sites."

The DX4515 Series Digital Transponder converts digital return and/or Ethernet signals in the node to a DWDM carrier on any of the 40 available wavelengths over distances of up to 100 km. This capability allows multiple nodes to share a common return path fiber, making the deployment of fiber-optic technologies deeper into the network a cost-effective strategy.

The chassis-mounted OP3500 and field-deployable OP9500 Series Optical Passives provide low-loss, high-uniformity coupling, multiplexing and demultiplexing functions, as well as customized passives that enable cable operators to provide advanced services more cost-effectively than with competing products, Aurora claims. In addition, all Aurora field optical passive products, including 100-GHz DWDM passives, are fully tested and guaranteed over the temperature range of -40 to +85 degrees Celsius.
