VDSL2 vectoring chip enables full system-level crosstalk noise cancellation
The chip is well suited for the delivery of triple-play broadband services, including multiple streams of HD-quality TV, Internet and voice. Used in Central Office (CO) or neighborhood/in-building cabinets, the VINAX IVE1000 uses advanced signal processing techniques to cancel Far-End Crosstalk (FEXT) between any of the VDSL2 lines in a copper bundle. By eliminating crosstalk service providers are able to achieve 100 Mbps symmetrical and beyond. The device enables up to 20% of power saving in a fully-vectored system (compared to non-vectoring) as a result of optimal balancing of transmission power. Connected to a vectoring standard-compliant CPE device such as the Lantiq XWAY VRX200, this combination allows the implementation of a complete end-to-end vectoring solution. Lantiq’s XWAY VRX200 CPE device is “vectoring ready” today, as such only a simple software upgrade is necessary for full vectoring functionality.
What is Vectoring?
Approved as an ITU Standard (G.vector or G.993.5) in March 2010, vectoring is a Dynamic Spectrum Management Level 3 technique (DSM Level 3) that coordinates signal strength across multiple lines by real time crosstalk mitigation. The benefits of crosstalk cancelation are largest when all lines in a binder are managed (i.e., at the system level).
The Lantiq VINAX Vectoring System is compliant with and is capable of supporting all features defined in ITU G.993.2 (VDSL2), G.993.5 (G.vector) and ITU G.997 (G.ploam). The solution applies to all VDSL2 profiles and supports up to 384 VDSL2 ports by cascading multiple VINAX IVE1000 devices. Visit Lantiq at www.lantiq.com
