FTTC / FTTC with Vectoring - Fiber to the curb
The DSLAM has to be installed closer to the customers to provide higher bandwidth to many subscribers via VDSL2. The infrastructure for this is typically a FTTC installation (FTTC – Fibre to the Curb). In FTTC architectures the optical fibre ends in a street cabinet. From this point the copper wires will be used. Theoretically data rates of 100 Mbps can be achieved with VDSL2 – 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 caused by a rising number of VDSL2 connections. Vectoring compensates the crosstalk almost completely on all connected subscriber lines. This gives a significant boost to the achievable data rate.
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).
