At the Broadband World Forum (BBWF) 2017, Huawei released its SuperFTTB solution. It uses 212 MHz G.fast technology to enable operators to support gigabit access through copper lines. It also provides easily deployed flexible fiber-copper dual backhaul, reducing network construction periods and accelerating return on investment (ROI).
With operators confronted with fierce market competition and the need to effectively plan future broadband development, rapid and smooth evolution of networks is increasingly important. Huawei presented the solution to help mainstream operators resolve the challenges of gigabit evolution, smoothly evolving FTTC (100 Mbit/s or over 100 Mbit/s) to FTTB (1000 Mbit/s).
Huawei's new solution supports fiber-copper dual backhaul, allowing operators to choose the most suitable backhaul mode. Under the SuperFTTB solution, the system supports a maximum of 8-pair SuperVector or VDSL2 vectoring copper line bonding. This means that operators can choose any 8 pairs without the need of re-jumpering, and can then establish 2 Gbit/s@300m or 1 Gbit/s@500m backhaul channels between sites and remote gigabit access modules. When no fiber backhaul resources exist, the SuperFTTB solution facilitates FTTC-to-FTTB upgrades by simplifying engineering for operators.
In fiber coverage areas, the SuperFTTB solution provides gigabit access services for more users by enabling integrated remote gigabit access modules to use fibers multiple uplink modes, such as XG-PON and XGS-PON. By implementing this solution, operators are able to use the same types of devices in different scenarios, simplifying processes such as IT integration, device purchase, and O&M.
Remote gigabit access modules in the solution support the latest 212 MHz G.fast technology and deliver downstream bandwidth of 1 Gbit/s at a distance of 100 meters. Moreover, the SuperFTTB solution is compatible with VDSL2, vectoring and 106 MHz G.fast terminals, ensuring smooth service migration for operators. In addition, the SuperFTTB solution offers concise NMS interfaces, greatly simplifying operations support system (OSS) interconnection profiles and operation processes, and effectively reducing IT integration duration during new solution introduction. In this way, operators are able to build networks rapidly, reducing time to market (TTM).
The history of copper line evolution shows that the global communications industry can continue to mine the potential of copper lines through technology innovation, meeting users' requirements for increasingly high bandwidth. Huawei says it will continue to work with world-leading operators to create innovations that accelerate gigabit access.
