Networking: VDLS How it works
VDSL is a type of broadband internet that delivers data over existing copper telephone lines, similar to ADSL—but much faster over short distances.
Uses phone lines (copper)
VDSL runs over the same copper wires used for landline phones. Internet data and phone calls use different frequency ranges, so they can work at the same time.
Short distance = high speed
Speed depends heavily on distance from the provider’s equipment. The closer you are, the faster it is.
Typical setup: Internet Provider => Street cabinet (DSLAM) => Your house / Office.Best speeds usually within 300–800 meters of the cabinet.
Modulation & frequency
VDSL sends data using high-frequency signals. Higher frequencies = higher speeds, but they fade faster, which is why distance matters more than with ADSL.
Download vs upload
- VDSL can be asymmetric or symmetric:
- Asymmetric: faster download than upload in the case of BT 80/20 is a common speed seen as the base connection.
- Symmetric: similar upload and download speed BT Lease Lines as an example will offer a 100/100 or 1000/1000..
Typical speeds
| Technology | Download | Upload | ADSL | up to ~24 Mbps | ~1 Mbps | VDSL | 50–100 Mbps | 10–40 Mbps | VDSL2 | up to ~300 Mbps (short distance) | higher uploads | Fiber Optic | 10Gbit | 10Gbit |
