Lantiq announced first customer shipments of its VINAX IVE1000 System-Level Vectoring Engine chip. Noise cancellation technologies – standardized in G.vector – eliminate crosstalk, but only system-level vectoring solutions, like the Lantiq vectoring engine device, more than double data rates and reach to meet operators’ next generation needs. The device demonstrates a breakthrough in full system-level vectoring capability, scalability and expandability up to 384 ports, considered to be ideal for 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. Major reduction in system power consumption: Up to 20% power saving in a fully-vectored system (compared to non-vectoring) as a result of optimal balancing of transmission power.
With VINAX V3, carriers can install “vectoring ready” VDSL2 line cards (which support ADSL2/2+ through VDSL2 30MHz standards) today, requiring only a remote software upgrade when the VINAX IVE1000-based central vectoring card is added at the CO or in a local cabinet. Connected to a vectoring standard-compliant CPE device such as the 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. This high level of scalability, coupled with the compelling features offered by the VINAX V3 chipset, results in a solution that is ideally suited to a wide range of applications such as MDU, MSAN and DSLAM.
