Correct all copper based broiadbands are slow with length of line.Martinspuddle wrote: ↑Sun Jun 14, 2020 8:18 am
@Jon_D our download speeds ain't much better sometimes as we here are still on overhead telephone wires and as I was told by a BT engineer the so called 'superfast' fibre broadband cable only goes as far as the green box in the main road, so we lose speed from there onwards.
with standard DSL/ADSL the copper from your house goes all the way back to your local exchange where it splits into Voice & Datawith the broadband being connected by fibre back into your providers core network.
The further from the exchange the slower the speeds (although other factors such as quality of copper, number of junctions ect also come into play.
FTTC (Fibre to The Cab) aka VDSL or superfast essentially moves the exchange equipment closer to the premises and splits it into voice & data at the green cabinet with the voice going back to the local exchange via copper and the Data going back to either the local exchnage or a Metro exchnage for the area using fibre.
VDSL achieve higher speeds than ADSL but also drops speed far quicker with distance which is why the exchange equipment has to be moved to the local cabinet
FTTP (Fibre To The Premises) which is starting to be rolled out in some areas does what it says on the lid and brings the fibre directly into your house giving you extremely high speeds that are not length dependent as they use fibre optic for the entire run.
