FTTdp Broadband Tech

It looks as if OFCOM are trying to get BT to trial FTTdp

Ofcoms Statement

�Installing FTTDP with the existing copper wire being used for the final few meters could be more cost effective than deploying fibre all the way to the premise. It is generally considered that FTTDP would be most effective when used with a developing technology called G.fast, which can be thought of as an evolution of VDSL.�

I don't read anything into that statement as Ofcom trying to get anyone to do anything. It is a fairly accurate statement of the way things stand with FTTdp, G.Fast and copper vs fibre.

In any case, BT have already stated that it is a possible future technology, as part of the evolution of FTTC. They went as far as to say "Trial TBD" in the quarterly results, but you can bet it is already running in Martlesham.

Nice to see Ofcom noticed a new DSL standard and rightly so as it has potential to destroy FM transmissions just like ADSL could of with AM radio

FTTdp? To what does this Acronym stand for?

Fibre to the drop point

Fibre to the Distribution Point (according to Google)

Sorry, Andrew, 11 seconds apart, near enough simultaneous...

Thanks Andrew.

So is that the hole in the ground between the cab and a given group of properties?

Yes that or the final telephone pole, or could just as easily be a new small box attached to the outside wall of a small block of flats.

Risk of interfering with FM is low and of course in theory FM is due to go and be replaced by digital

With FTTdp they could possibly do away with the need for mains power by using rechargeable batteries and solar xells

Reading a bit more on it they seem to have a solution to the power problem they are talking about using a reverse power feed from the premises. I assume they are talking about using the 48V line voltage. Where it can deliver enough power in the UK I don't know.

If anyone fancies a trip to Amsterfam they should find out more

Lantiq and Aethra® Telecommunications will demonstrate their FTTdp solution, which enables service providers to deploy CapEx efficient solutions today offering significantly higher data rate performance, at Broadband World Forum (BBWF), October 16-18 in Amsterdam (Lantiq Booth C4)

No. Reverse power frm the premises is not "48V line voltage" (from the exchange) it's using CPE in the receiving premises to power the kit.

"Low-Cost, Low Power (10 Watt) Mini
Distribution Points Get Power Remotely
from a Home�s Modem" as per the link.
