FTTC / FTTC with Vectoring - Fiber to the curb

In der FTTC-Architektur endet das Glasfaserkabel in einem Kabelverzweiger (KvZ). Mit VDSL2 lassen sich Datenraten von über 100 Mbit/s erzielen; allerdings nur bei kurzen Leitungslängen und wenigen VDSL2-Teilnehmern im Kabel. In der Praxis ist das Übersprechen (FEXT, Far-End-Crosstalk) zwischen den einzelnen VDSL2-Signalen auf den Kupferleitungen mit dafür verantwortlich, dass die theoretische Datenrate nicht erreicht wird.

Vectoring bietet hierbei eine Lösung, denn es kompensiert das Übersprechen im Kabel nahezu vollständig und steigert so die zu erzielende Datenrate deutlich.

 

In FTTC architectures the optical fibre ends in a street cabinet. With VDSL2, data rates of 100 Mbps can be achieved – however only on short loops and with only a few VDSL2 subscribers in the cable. In the real world the far-end crosstalk between the copper wires with VDSL2 signals in the cable reduces the data rates, so that the theoretical value cannot be achieved.

Vectoring is the solution for the challenge as it compensates the crosstalk almost completely on all connected subscriber lines. This gives a significant boost to the achievable data rate.

MileGate 2510

IP-MSAN MileGate is a compact DSLAM with highest port-density. With it, up to 960 with vectoring extended VDSL2 ports can be provided out of one 8 HU subrack. With MileGate network operators can offer their customers more than 100 Mbps in downstream direction and over 40 Mbps in upstream direction even in mass deployments for comprehensive services like VoIP, broadband Internet, Video-on-Demand and TV via DSL (IPTV).
