What were the cables installed in the 80's (or was it 70's?)

Go to solution

Hi

I know a lot of people (including me) have speed probs to do with Ali cabling.

But.....

In the 80's (I think it was) all the roads in the country were dug up to install what I thought were fibre optic cables.

Is this right and if so, why are some phonelines coming down Ali?

by no means many lines are still either copper or aluminium other wise every one would now be on fibre to home by now the main trunk routes an internet backhaul between exchanges can be fibre but unless in areas of the uk where fibre to home is available Bt are now providing voice over fibre if you read this link one community in the UK will be trialling total fibre soon http://community.bt.com/t5/BT-Infinity/Deddington-to-be-UK-s-first-all-fibre-telephone-exchange/td-p...

I think what you were seeing in the 80s was the installation of DOCSiS3 cable, suitable for cable TV and high speed broadband, and not fibre. As for aluminium, it was fitted extensively in the 70s owing to the high price of copper, but nowadays BT use copper for new lines. One typical broadband graveyard is Milton Keynes, where the entire phone network was based on ali cable I believe. Welcome to correction if I'm wrong.

Yes, MK is well knows as being an aluminum deathtrap as far as ADSL is concerned due to it being mainly built during the copper crisis.

 

Roger's also right that the last major cabling blast in the 80s was for cable TV and telecoms, unfortuately the cable cos are no longer interested in extending that network.

So what are the cables installed for "high speed broadband" at that time being used for?

 

All those dead trees for nought?

Hi,

 

What the OP may also have seen is the laying of ducting, a lot of which has never been utilised.

This was mainly in cities and large towns, none in rural areas.

Best regards,

The MK issue is partially right, the were some areas fitted with fibre. But as a POTS. Togetherwith an exchange which is nowhere near where its name suggests and even further from the area it serves.
