Aurora Networks Helps Cable Operators Increase Network Bandwidth with Segmentation Toolkit

By Nathesh, TMCnet Contributor

Aurora Networks, a provider of solutions for building future-proof networks to accommodate the cable subscriber services, announced that it has released a complete segmentation toolkit for the cable industry fulfilling the company’s commitment to help them cost-effectively increase bandwidth of the network.

Aurora Networks’ segmentation toolkit includes cost-effective products for both the downstream and the upstream paths. Utilizing the kit, operators can realize full downstream and upstream segmentation for multiple nodes on just one fiber.

Officials with the company asserted that a proper segmentation strategy exploits the existing network resources to maximize bandwidth-per-subscriber while minimizing capital expenditure. This enables cable operators to achieve a new level of quality-of-experience for the subscriber. Aurora’s product breadth enables their network architects to evolve their customers’ networks, attaining their service goals without wasteful overspending.

The company claimed that it offers Alternative Node Segmentation Technologies for forward applications and they include: LcWDM for low-cost and most node segmentation needs, DWDM for large capacity requirements, and D2WDM for topology-specific applications. Technologies for reverse applications include: CWDM optimized to meet most node segmentation needs, and DWDM for coverage over longer distances.

Aurora's AT3545G series high performance Full Spectrum (News - Alert) Transmitters are a key element of Aurora Network's HFC and FD architectures in support of the evolution to all QAM transmission and are designed for Dense Wave Division Multiplexing (DWDM) applications for point-to-point forward path transmission of full spectrum broadcast and narrowcast services. It is one of the downstream segmentation solutions from Aurora.

Aurora's solution for service area segmentation using LcWDM technology allows pursuit of new revenue streams by enabling the reuse of fiber up to eight times over distances up to 30 km.

Aurora Networks added that its digital return technology is optimized for segmentation, with more than 80 return segments supported on just one fiber. The company’s very cost-effective CWDM solution supports up to 15 wavelengths. For even greater reach and fiber efficiency, the DWDM solutions support up to 40 wavelengths.
