Aurora Networks Introduces AT3545G Series Full Spectrum Transmitters
Aurora Networks Unveils Revolutionary Full Spectrum Transmitters for Delivering Broadcast and Narrowcast Services
Company’s AT3545G Solution Supports Cable’s CMAP Initiative, Covers Full Spectrum of Analog and Digital Channel Loading Combinations
Aurora Networks, Inc., the only optical transport solution provider focused on delivering a cost-effective, optimized platform for next-generation cable services, today introduced its AT3545G series full spectrum transmitters that enable a cable network’s evolution to full QAM capabilities, including a seamless migration to future CMAP (Converged Multiservice Access Platform) deployment.
Aurora Networks’ development team has optimized this new technology for deployment in two very diverse applications.
The first version, the AT3545G-xx-1-AS series ‘C’-band DWDM transmitter, supports light analog channel loading plus QAM loading up to 1 GHz for delivering digital services. This transmitter also supports the planned CMAP initiative, a key component of the next-generation access architecture cable operators are developing to consolidate technologies delivering narrowcast services into a single platform. The CMAP concept creates a converged platform to save headend space, reduce energy consumption and cut the cost of delivering advanced services to customers.
The second version of the transmitter, the AT3545G-xx-2-AS, is optimized for full analog channel loading up to 550 MHz along with QAM channel loading up to 1 GHz. This unit is optimized for node segmentation; a very cost-effective technique to significantly increase bandwidth without expensive fiber construction.
Aurora Networks is displaying the AT3545G series transmitters in its booth, No. 1552, at SCTE Cable-Tec Expo 2010.
What Aurora Networks Says
“Aurora Networks’ latest high performance, full spectrum DWDM transmitters lay the foundation for the eventual progression to all QAM transmission,” said John Dahlquist, vice president of marketing, Aurora Networks. “These transmitters support the cable operator’s ongoing strategy to reclaim analog bandwidth and to assist them as they utilize the full network spectrum for delivering broadcast and a consistently growing slate of narrowcast services.”
AT3545G Details
- For supporting analog services, the first version of the AT3545G transmitter provides up to 260 MHz analog loading while the second version delivers up to 550 MHz analog channel loading.
- The AT3545G transmitters incorporate a user-selectable RF input gain technology that permits lower RF input levels. As cable operators further segment their networks, they may encounter an increased amount of loss in their RF management network which is used to route more QAM channels to new smaller service areas. The RF input gain technology contained within the AT3545G allows cable operators to compensate for that signal loss without having to purchase shelves of space-consuming RF amplifiers.
- These transmitters enable the transmission of full spectrum (both analog and QAM) channel loading over 50 km distances. For full spectrum QAM-only loading, the reach may top 60 km. Both applications support up to 16 wavelengths per fiber.
- As a narrowcast transmitter, the unit will support more than 120 QAMs over 40 wavelengths per fiber.
- The compact size of the AT3545G series transmitters reduces rack space requirements within headends and hubs.
