More than doubling data rates and reach for next-generation networks based on VDSL2, the Vinax IVE1000 system-level vector engine chip is from Lantiq. Described as a major milestone towards a broad deployment of vectoring in the field, it is claimed to be the industry's first integrated ASSP for volume deployment of system-level vectoring, supporting up to 384 VDSL2 lines. (Noise cancellation technologies, standardised in G.vector, eliminate crosstalk, but only system-level vectoring more than doubles data rates and reach.) VDSL2 vectoring was defined by the ITU to enable service providers to boost the bandwidth on their widely deployed copper infrastructure to 100Mbit/s and beyond. The capability to support up to 384 channels is considered to be ideal to deliver triple-play broadband services, including multiple streams of HD-quality TV, Internet and voice. The engine supports full cancellation and partial cancellation for cost-effective, future-proof, broadband infrastructure deployment, says the company. The engine can be used in central office or neighbourhood and in-building cabinets, using signal processing to cancel FEXT (far-end crosstalk) between any of the VDSL2 lines in a copper bundle. The engine also reduces system power consumption. The company reports up to 20% power saving in a fully-vectored system (compared to non-vectoring) as a result of optimal balancing of transmission power.
