What is ADSL?
ADSL is nothing but, Asymmetric Digital Subscriber Line. ADSL is known for transmitting data at high bandwidth. It entails the transmission of audio, video, and a variety of data. The distance determines the speed of the connection in ADSL. In general, the speed will be higher if the distance between the home and network equipment is shorter.
An ADSL connection can provide speeds of up to 24 Mbps. The ADSL connection is made up of pair of copper wires responsible for carrying out signals. This line employs different frequencies for voice transmissions and internet connections. The ADSL connection is much more affordable than any other connection.
ADSL 2+ is the most recent version of ADSL connectivity. Even though the ADSL connection is a little bit slower than other connections, it covers a larger distance. The maximum coverage of this type of connection is 18000 feet, which is amazing. And ADSL also supports plain old telephone service and asymmetric data.
What is VDSL?
The acronym VDSL stands for Very-high-bit-rate Digital Subscriber Line. When compared to other connections, VDSL is noted for its greater speeds. VDSL supports high bandwidth devices. By employing a VDSL connection, Internet application users can enjoy a smoother, faster surfing experience. It also has a higher capacity and is more secure.
Video on Demand and High Definition Television is made possible via VDSL. The coverage of the VDSL connection is 4500 feet. VDSL, on the other hand, is known for its symmetric data offerings and POTS service. Even though VDSL has a faster connection, it is only good for short distances.
Furthermore, the pricing is not very reasonable. Internet usage, surfing, downloading all becomes swifter in the VDSL connection since it transfers data at 55 Mbps downstream and 2.5 Mbps upstream. VDSL is also less difficult to set up. In this sort of connection, the signal is sent by a pair of optical fibres or copper wires.
Difference Between ADSL and VDSL
- The full form of ADSL is Asymmetric Digital Subscriber Line. In the meantime, VDSL stands for Very High Bit Rate Digital Subscriber Line.
- ADSL is capable of covering distances of up to 18000 ft. A VDSL connection, on the other hand, can only cover 4500 feet.
- ADSL is a cost-effective connection when compared to other options. VDSL, on the other hand, is far more expensive than conventional connections.
- The downstream speed of an ADSL connection is 599 kbps to 8 Mbps, and the upstream speed is 64 kbps to 1 Mbps. VDSL, on the other hand, has a downstream speed of 55 Mbps and an upstream speed of 2.5 Mbps.
- Asymmetric data service is provided by ADSL, whereas symmetric and asymmetric data services are provided by VDSL.
Comparison Between ADSL and VDSL
|Parameters of Comparison||ADSL||VDSL|
|Full form||ADSL( Asymmetric Digital Subscriber Line).||VDSL(Very-high-bit-rate Digital Subscriber Line)|
|Price||When compared to other connections, an ADSL line is much less expensive.||VDSL is significantly more expensive than other connections.|
|Coverage||An ADSL connection can range up to 18000 feet.||VDSL can only traverse short distances, such as up to 4500 feet.|
|Speed||In an ADSL connection, the download speed is 24 Mbps.||VDSL provides a high download speed of 70 mbps.|
|Signal loss||The signal strength of an ADSL connection does not deteriorate quickly.||A VDSL connection might quickly deteriorate.|
