OCTOBER 19, 2009 -- Rapidly growing demand for backhaul capacity from wireless network towers has created an emerging market for cable operators with fiber-rich networks. Aurora Networks Inc. says it is providing a standards-based offering that enables cable operators to compete for a share of such backhaul business.

Aurora Networks’ cell tower backhaul approach features the GT3410A T1/E1 Access Module, designed to provide Ethernet-based circuit emulation that enables delivery of TDM traffic over high-capacity Ethernet fiber. When deployed at base stations and base station controllers, the GT3410A delivers Ethernet-over-cable transport capabilities, providing both the T1/E1 and pure Ethernet support that wireless carriers require, Aurora Networks asserts. As exemplified by its Metro Ethernet Forum MEF-18 certification, the GT3410A is engineered for the stringent requirements of cellular backhaul, the company says.

At next week’s Cable-Tec Expo, Aurora Networks will introduce high-density passives and a plug-in 1-Gbps transceiver module optimized for cell tower backhaul deployments. The passive components are engineered to make it easier for cable operators to overlay return fiber from the node to the headend. They also enable operators to backhaul traffic up to 80 km (nearly 50 miles) from four or five cell towers over the same fiber as the existing node return. With a passive module customized to support C-Band transport as well, a further 34 DWDM wavelengths can be carried on the same fiber, providing support for future revenue-generating services, Aurora Networks says.

“Cable operators are in the perfect position to address the growing needs of the cell tower backhaul market with an integrated fiber solution that leverages existing network resources and meets all requirements for wireless backhaul support,” said John Dahlquist, vice president of marketing, Aurora Networks. “The cost-effective wireless backhaul solution Aurora Networks provides addresses this growing opportunity, and it puts cable operators in an ideal situation to compete aggressively with other companies serving the cell tower backhaul market.”
