Lantiq Samples System-Level Vectoring Chip

Lantiq announced first customer shipments of its VINAXTM IVE1000 System-Level Vectoring Engine chip.


The company said its new VINAX IVE1000 represents a major milestone for the deployment of vectoring in the field. The chip is an integrated ASSP solution suitable for volume deployment of system-level vectoring solutions supporting up to 384 VDSL2 lines.


The implementation supports full cancellation and partial cancellation of crosstalk in copper bundles. Specifically, Lantiq's VINAX IVE1000 uses advanced signal processing techniques to cancel Far-End Crosstalk (FEXT) between any of the VDSL2 lines in a copper bundle. This enables service providers to achieve 100 Mbps symmetrical and beyond, according to the company.
In addition, Lantiq said its technology enables up to 20% system power savings in a fully-vectored system (compared to non-vectoring) as a result of optimal balancing of transmission power.


The VINAX V3 enables “vectoring ready"? VDSL2 line cards (which support ADSL2/2+ through VDSL2 30MHz standards), 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 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.


Lantiq noted that is 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.
