Alcatel-Lucents DSL Phantom Named Broadband Innovation of the YearAlcatel-Lucent has received the Broadband InfoVision Award in the “Broadband Innovation of the Year” category for its DSL Phantom Mode breakthrough.

DSL Phantom Mode adds a whole new dimension to the ongoing ‘100Mbps for all’ debate, effectively bridging the gap until nationwide fiber-to-the-home deployments have been completed.

It offers service providers the perspective of enabling their existing copper infrastructure - widely deployed around the world - to satisfy demand for bandwidth-intense residential triple-play and business services, for years to come.

Building on VDSL2 Bonding, Vectoring and the analogue “phantom mode” concept, Alcatel-Lucent’s research arm Bell Labs has successfully demonstrated how this technology boosts transmission speeds attainable over traditional copper wires.

Leveraging DSL Phantom Mode, Alcatel-Lucent has shown downstream speeds of 390 Mbps over distances up to 400 meters using two copper pairs, commonly available in residential deployments. By adding more pairs, even higher speeds can be obtained (for instance, 910 Mbps at 400 meters using four pairs – which means more than 1Gbps upstream and downstream combined).

The availability of more than two copper pairs is particularly relevant in business services environments, and to support mobile backhaul.
