You might not be completely surprised to learn that 10-Gbps backhaul systems have been developed to support fiber-to-home networks. Alcatel-Lucent, for example, has done so. The same developments are occurring in the wireless backhaul area as well, with firms such as Cambridge Broadband Networks launched its 10Gbps multipoint microwave backhaul platform.
The VectaStar Radio Controller (RC), the latest development of the company’s VectaStar microwave backhaul and access solution, is designed to meet the growing capacity requirements of mobile operators. The RC is a native Ethernet VectaStar hub that currently supports doubling of sector performance to 300Mbps, with planned upgrades this year to deliver 600Mbps and 1Gbps.
Australia-based Ngara also will conduct field trials of 10Gbps microwave backhaul in early 2012. Current wireless backhaul links that top out at 150 Mbps across tens of kilometers are seen to be “insufficient” for next generation broadband applications.
