The new Highspeed VDSL Technology
What does the term vectoring mean?
VDSL2 vectoring is the current advancement of VDSL2 and makes it possible to double data rate. To achieve this, vectoring technology eliminates undesirable crosstalk in already existing copper network. As a result, bandwidths of up to 100 Mbit/s downstream and up to 40 Mbit/s upstream can be reached.
What are the benefits of VDSL2 vectoring?
VDSL2 vectoring is interesting for all customers who have demand for high bandwidth and no chance of getting fiber access in the near future. Customers who have been using VDSL 50 can be pleased to have double download rate (100MBit/s) and a four times higher upload rate (40MBit/s).
How do bintec elmeg customers benefit from VDSL2 vectoring?
Customers who switch to VDSL2 vectoring can already purchase the required devices from bintec elmeg. With the new bintec RS series, we offer our customers high-quality VDSL business routers which, of course, are all vectoring-ready.
bintec Routers – of course Vectoring-ready
In order to provide end customers with vectoring technology, both network providers and customer’s hardware have to comply with the requirements.
The following devices are predestined: bintec RS353j, bintec RS353jw, bintec RS353jv-4G, bintec RS353a, bintec RS353aw
The schedule of VDSL2-Vectoring
Currently VDSL2-Vectoring is in the expansion stage. Vodafone has already implemented the conversion in the following districts: Hilden, Velten, Kiel, Gifhorn, Löhne, Zweibrücken, Neuhof, Neuhof- Hauswurz, Beilstein, Tübingen, Albstadt- Ebingen, Offenburg, Starnberg and Kalbach, Wegberg, Wegberg-Rödgen, Gronau- Westphalia, Gronau-Epe, Hennigsdorf, Kleinmachnow, Rendsburg, Hosenfeld and Waldenbuch.
Deutsche Telekom wants to increase the number of VDSL-capable connections, which also support Vectoring, from 12 million (mid-2014) to 24 million. Providers who also use the telecom network also benefit from this conversion (for example, O2, Congstar, 1 & 1, other local providers).
DSL Vectoring – Procedure without Vectoring
Data stream is transferred from MDF to an SAI via fiber optic and subsequently led to single houses or subscriber lines via copper cables.
- SAI receives data signal where fibre optic and copper cable come together.
- Transmitted signal without vectoring: at DSLAM transmitted signal is transferred to copper cable.
- Unshielded copper wires interfere each other by their signals. This substantially limits the maximum operating range and bandwidth. As a consequence, the received signal has interferences
VDSL Vectoring – Procedure with Vectoring
Also here data stream is transferred from MDF to an SAI via fiber optic and subsequently led to single houses or subscriber lines via copper cables. A special DSLM in SAI neutralizes signal interference.
- SAI receives data signal. Fiber optic and copper cable come together.
- Transmitted signal with vectoring: special DSLM measures interference between copper wires and sends opposing signal in order to neutralize signal interference.
- Transmitted signal: an interference-free signal increase bandwidth and range
