ADSL service has a maximum distance of 18,000 feet (5,460 m) between the DSL modem and the DSLAM, though for speed and quality of service reasons, many ADSL providers place an even lower limit on the distance. How fast is VDSL? Poll. The (potential) new place is, however, around 2400m from another exchange. Signal loss is much greater at the higher frequency's that VDSL uses and is also affected by increased power on longer lines. Similarly, ADSL2 can work up to 5.5km but you need to be no further than 1.5km to get 12Mb/s. NBN MTM Alpha: Unofficial Tech/Speed Estimates. These characteristics of the copper wire directly contribute to the noise on the line and their effect is greater the longer the line. First thing’s first: check what Telkom says your maximum supported line speed is. This is commonly referred to as 'noise' and is explained at the end of this article. On the other hand, VDSL provides 55 Mbps downstream bit rate and 2.5 upstream bit rate. This decision was made because most users receive more data than they send. Discussions of specific services based on ADSL, cable modems or other broadband technology are also on-topic. Distance from the exchange plays a big role in potential VDSL speeds. Essentially, the standard ADSL can work up to 5.5km from the exchange. Advertising is not allowed. From May 1, 2013, VDSL2 is also offered to private customers with speed 30/10.

Telkom 20Mbps ADSL2+ service launched. distance = rate x time. However, to get 8Mbit you would need to be located no further than 2km from the exchange. ASDL takes advantage of the higher frequencies on the copper wire which are not used by voice. ADSL and ADSL2+ are delivered to your home over copper wires, and because of this, the speed of your connection to the network is impacted by the distance the information needs to travel between the exchange and your home. Whilst attenuation is normally directly linked to the length of your line, there are a few other important factors to bear in mind as to why the above calculator can only be used as a guide. The ADSL connection/feed is done directly within the Exchange, with no changes to the PCP wiring. Note that is based on what VDSL is technically capable of and the setup here in NZ may give slightly different results. There are devices that improve broadband signal quality and reduce noise - such as the micro-filters that many consumers have fitted in their homes. You can use the equivalent formula d = rt which means distance equals rate times time. Further speed upgrades for full fibre to 1Gbps (1000Mbps) are expected to be on sale later in 2017. DSL is a distance-sensitive technology: As the connection's length increases, the signal quality and connection speed decrease. ADSL2+ offers the best line speed (24Mb/s) up to 1Km from the exchange. ADSL technology covers a larger distance than VDSL, where ADSL can cover 18000 feet, and VDSL can reach up to 4500 feet. Unlike cable, broadband connections using ADSL broadband technology is distance-sensitive: the further you are from the exchange the slower the connection. Similarly, ADSL2 can work up to 6km but you need to be no further than 1.5km to get 12Mb/s. Even with noise on the line that causes you to miss some of the words you can still understand the conversation. 17 May 2020 by Dr Mark Heath ‘Fibre broadband’, or Fibre-to-the-Cabinet (FTTC) as it is more formally known, is the technology that delivers the vast majority of superfast broadband connections in the UK currently. Re: Is there a distance vs speed calculator out there? Ceasing VDSL and providing ADSL instead - what's involved by BT? To understand why noise exists we need to look at how traditional telephones work. It may be possible you have a RIM/Top Hat closer which is like a sub-exchange, so your distance is based on the distance from that. Copper wires are used to transmit voice calls using the frequencies up to 3400 Hertz. DSL speed and copper length graph More on Telkom ADSL and VDSL.
