FTTP on demand

[newshound]

And why not? The government has only committed to making it increasingly available, not affordable!

Don't forget the later Gfast FTTC. I can get 330Mbps, apparently, where I live. I could get 1Gb from Gigaclear but I'd prefer to stick with an ISP I know.

[Roger Hayter]

FTTPoD is fibre on demand. It is the same thing as FTTP, but customer funded infrastructure.

[The Natural Philosopher]

Actually often it isnt the same thing

[Roger Hayter]

Given FTTPoD is only available where Openreach have suitable infrastructure I would be really surprised if they agreed to a plan inconsistent with their planned build. They certainly didn't near us when I got a quote for FTTPoD. Perhaps it varies with district.

I think you could get it wherever you want, but you might have to look at a supplier other than Openreach.

Cost will of course be very significant - I've heard figures of £50k plus, subject to survey ...

[The Natural Philosopher]

Well fttpoD is a replacement for VDSL copper to the street cab FTTP is fiber to the exchange it

A few months back City Fibre ran cable down the street where I live. At the same time they installed a green cabinet on the pavement.

[wasbit]

Ditto with Gigaclear. They have installed at least 4 small cabinets within 200 metres of each other & all are less than 500 metres from the Openreach cabinet.

[Theo]

Do they look like they have equipment in them?

I wonder if this is because Openreach have gone for GPON, which is a shared medium passive optical network, in other words you have to share bandwidth with your neighbours, and it limits upstream bandwidth. Meanwhile some of the others give you a dedicated fibre so your bandwidth is symmetric. You can get 1G/1G (up to the limit of the gigabit ethernet port on your ONT/router) whereas Openreach can only offer 1G/115M.

Theo (who can't help feeling that GPON is a hostage to fortune in the same way DOCSIS turned out to be)

[The Natural Philosopher]

There is nothing about the way openreach use the fibre that precludes synmmetrical working - that is a commercial, not a technical, choice

And although the fibre is shared, it is TDM, so there is no contention with other fibre users.

It depends. There is clear evidence that the average consumer is in fact a consumer of data, and not a supplier, so asymmetric channels make sense.

[Andy Burns]

The TDM only applies on the upstream, every OLT sharing a splitter receives the same downstream traffic and filters outeveryone else's packets.

^^^ ONT

[Robin]

I think Gigaclear have gone for 100% PtP fibre. AINU (which is v little) that requires more active kit locally (hence cabinets) and is more expensive to instal but, as you say, makes it easier to deliver ever higher speeds i.d.c.

[Robin]

sorry, for AINU pl read AIUI.

(Personal dictionary now restored.)

[Andy Burns]

BT are planning to use XGPON instead of GPON for 10 gig speeds in future, and to use coarse wavelength multiplexing so that both can exist on the same fibre at the same time to allow gradual migration on a customer-by-customer basis.

Then presumably NGPON2 at 50 gig and beyond?

I look forward to 3Dhologramtube

[The Natural Philosopher]

I think you will find its TDM downtream as well, but yes. other peoples packets are discarded - it learns which is 'its' TDM timeslot

[The Natural Philosopher]

If you cant smell it taste it and touch it, its not much cop

[Roger Hayter]

I think that may well be unfair. I tend to believe that the prices they charged, generally from 5000GBP to 50,000GBP were quite realistic reflections of the cost. Certainly a local FTTPoD quote was about half the price of the final Community Fibre Partnership, and would still have involved several new poles and 100m of ducts as well as a couple of miles of fibre.
