Duxbury Networking meets demands for higher backhaul capacity

A new E-band (70/80 GHz) microwave backhaul system designed for deployment in a wide range of applications, such as fibre extension/replacement, 3G/4G backhaul, disaster recovery and lease line replacement, has been released by Duxbury Networking.

BridgeWave Communications’ new Flex4G-5000 system allows telecommunications infrastructure operators to flexibly provision links across multiple network topologies including mixing Ethernet, CPRI, and SONET/SDH traffic.

The system is available in two models: the Flex4G-5000 ANSI and Flex4G ETSI. The ANSI system delivers up to 5.35 Gbps full duplex capacity per radio, and is scalable to 10.7 Gbps in a 2+0 configuration.

The ETSI system delivers 4.7 Gbps full duplex throughput per radio and scales to 9.4 Gbps in a 2+0 configuration. The radio requires a supply voltage of 48 volts DC and consumes up to 53 watts of power.

“These ultra-high capacity systems boast increased system gain for the highest throughput at the longest distance,” says Andy Robb, chief technology officer at Duxbury Networking. “Each model offers operators an alternative to fibre in dense urban areas and provides public and private network operators with a backhaul system that quickly scales to meet future capacity requirements.”

He says that Flex4G-5000 models alleviate the strain of backhaul connections by combining advanced radio and modem capabilities with carrier-grade 10G Ethernet, CPRI, and SONET/SDH features at the lowest total cost of ownership.

“The radio system supports highly integrated RF and spectrally efficient signal processing techniques to provide for the longest link distances, while maintaining multi-gigabit speeds and offering carrier grade features,” he notes.

Key features of the FL4G-5000 include radio link aggregation to combine capacity from multiple radios to a single Ethernet cable, simplifying operational logistics and reducing costs. In addition, the system’s multi-gigabit links allow operators seamless transition to 5G while redundancy is enhanced with fibre-quality wireless backup to fibre for mission-critical data.

“The Flex4G-5000 sets a new standard in capacity, data throughput, flexibility and value,” adds Robb. “Not only does the system offer carrier-grade features, it dramatically lowers the cost-per-megabit to provide mobile operators, service providers and enterprises with a lower total cost of ownership.”
