Nokia Siemens Networks demonstrates 825 Mbps DSL speeds

Nokia Siemens Networks is using this week's Broadband World Forum event to demonstrate 825 Mbps over 400 meters of bonded copper cabling and 750 Mbps over 500 meters.

Similar to a recent experiment conducted by Alcatel-Lucent, Nokia Siemens Networks also used a technique that creates a virtual--or 'phantom'--channels to supplement the two physical wires that are the standard configuration for copper transmission lines.

According to NSN and other advocates of Phantom DSL, service providers could see a 50-75 percent increase in bandwidth over existing bonded copper lines.

The latest move reflects NSN's near-term strategy to focus on high-speed hybrid copper/fiber-based last mile network technologies such as VDSL2. NSN plans to integrate Phantom DSL technology into its hiX 562x/3x DSLAM products. However, Nokia Siemens Networks' approach is not unique as it's also being used by both Alcatel-Lucent and Huawei with respective claims of transmitting 300 and 700 Mbps over existing copper.

Even though the momentum for Fiber to the Premises (FTTP) continues to gain ground with Verizon and even large MSOs such as Cox Business, there has been continual momentum from a number of large service providers (AT&T, BT, Qwest, Windstream and Tele2) to leverage existing copper to deliver broadband data and even video
