Cabinets that don't have fibre - where does it come from?

halfhearted — Fri, 15 Jan 2021 14:28:48 GMT

Am I correct in thinking that I have to wait for Openreach to connect my cabinet (I know the exchange & cabinet no.) to fibre before I can get the hybrid "Fibre-to-the-Cabinet"? Is the fibre coming from the exchange or is there a separate fibre system that bypasses the exchange. I'm puzzled that many cabinets locally seem to have a fibre connection but mine doesn't. I guess that's 2 questions really. Any clarification greatly appreciated.

The fibre may or may not come from your local exchange, it might come from a different exchange depending on the network topology in your area.

It may simply be that your cabinet hasn't been enabled because it isn't economically viable to do so.

in most cases the fibre does not come from your local exchange ,it comes from a main hub (large exchange ) with fttc your dial tone comes from your local exchange to the cab then the tone and fibre are joined and then that goes to the property . in most cases the fibre cab is near the old cab i.e other side of the road /round corner

confirms there is no fibre connection available to you and no date for any upgrade

Thanks. Is there a way of telling if the Mile End exchange would supply the fibre connection or if it would come from a larger exchange elsewhere?

your more likely to get FTTP then cabinet upgraded

How would knowing that be of any help?

People on the same cabinet have mentioned advertising from other commercial services who seem to be saying they can perform an upgrade, to the cabinet I assume, that would allow us to receive either FTTC or FTTP. I am guessing that the cost of such an upgrade would depend on the distance from the exchange that was supplying the fibre. Mile End is the closest exchange, about 1.8km, so it would be the cheapest. Possibly.

The only company upgrading the cabinet to FTTC would be Openreach. FTTP could be provided by Openreach or other fibre providers.

Physical distance to a node is only one factor in the cost of supplying FTTC/FTTP and doubt it would be the governing factor.

I see. Seems like my neighbours misunderstood. So the basic position is that there's no way round waiting for Openreach to put in an upgraded cabinet that has a fibre connection (either from Mile End or from some other exchange). Once they've done that then there may be other commercial services who will carry out FTTP connection for for a fee. Is that correct?

You may want to have a look here about Fibre Availability - Questions about fibre availability (openreach.com)

The 2 things are entirely independent. FTTP provision is not reliant on a cabinet being upgraded.

Interesting. What does it rely on?

Re: Cabinets that don't have fibre - where does it come from?

Just fibre infrastructure being provided from the serving node. FTTP doesn't come from the cabinet.

This shows how.

I think I'm mixing up FTTC and FTTP. Am I correct in thinking that FTTC is a hybrid which consists of a fibre connection to an existing street cabinet & then use of the existing copper cable to the premises?

Are you saying that FTTP bypasses this altogether and simply makes a connection from a local serving node directly to the premises?

Does a serving node look like some other kind of cabinet on street level?

See the diagram I posted. By serving node I mean the exchange containing the optical headend (OLT). The 32 way splitter is just an enclosure mounted on either a pole in overhead distribution areas or in joint box (manhole) in underground distribution areas.

If your cabinet hasn’t been ‘upgraded’ to FTTC by now, then there probably is a ‘commercial’ reason, why not, upgrading a cabinet to FTTC is undertaken if it’s going to give a return on investment , possible reasons that make a return less likely are, if the cabinet serves very few residential customers, ( this could be if cabinet mainly serves businesses and only a few non business lines ) or if the cab is in a relatively sparsely populated area, or ( not very common ) another company has already installed their own FTTC cab , ( called sub loop unbundling) it’s the same sort of setup as OR FTTC, but it means OR cannot provide their own ‘fibre cab’ due to the ‘interference’ that would occur if two FTTC cabs were connected to the same copper cabinet....if this is the case , the only way to get FTTC would be from that other provider.
