Any hope for long fttc lines ?


[link to this post]
 
My line syncs around 15mbps. It is roughly 900 yards from the cabinet.

Apart from saving for the next 10 years to pay for fibre on demand, what are the chances of people with longer lines being able to receive closer to the 40Mbps plus of others ?

How good are you at changing the laws of physics?

Even when/if profile 30 is rolled out it will not offer very much extra (if any) to those far away from the cabinet. Maybe a power increase or a new modem front end might improve the reception of low power signals but that is unlikely and even if it did the increase obtained would be small.

Vectoring may offer some hope too, there's been a few stories about it on the TBB news (have a look back through the archive).

15Mbps seems a little low for 900 yards, I'm 950m and get 28 Mbps.

if you said in metres I would have gave you an opinion based on whats achievable with vectoring.

I suspect BT are cutting back power to try and handle crosstalk, this in turn will reduce syncs.

BT Infinity 2 Since Dec 2012 - Estimate 65.9/20 - Attainable peak 110/36 - Current Sync 71/20

Vectoring will not add much ... at long distances it is the attenuation that is the real problem.

Although if FTTP on demand installation costs £1,500 at ten years that works out to £2.88 a week. I'm sure you could afford more?

But of course you were just being flippant.

No, there are other more (in the short term at least) cost effective options. You could have a second phone line installed and a second FTTC connection installed, each should sync at roughly what you're getting now but with an ISP that supports MLPPP you would see it as one single 30 meg line wink

Fibre enabled cabinets which are placed in the centre of a large housing developments will work well.
As you know VDSL goes down hill big time when we increase the distance from the cabinet to a point where it starts to level off with the performance of ADSL+2.This so called 'last mile' will always be a problem and the only way around it is for Openreach to use advanced copper technology in it's many different forms.See one example of this from the link below.

It could be aluminium cable.

I currently sync at 27mbps on a mixture of aluminium and copper along the route (as told to me once by a BT Engineer acquaintance) approx 800m from the cab.

There was talk that a full implementation of vectoring might allow 50mbit at 1000 metres, and 100mbit with bonding.

Your line clearly isn't very good though - I am on adsl2+ at 1150 metres from the exchange and get about the same as you.

Have you done all the usual test stuff, disconnecting extension wiring etc?
