Phone Cable Question

[Signor Bob]

Hello,

Not sure where is best to post this. I have fibre optic Internet by Open Reach. The cable comes up through a grey plastic conduit and into the box on my house. At the front of the garden, next to the highway, a cable comes in under the garden wall (the old BT metal grid is on the footpath on the other side of the wall)...

Is the cable I have unearthed the fibre optic or the old analogue cable? It is a metallic, twisted material inside a clear plastic exterior (like a bicycle cable lock).

Thanks

The second pic looks like the old copper service.

It's certainly not the fibre service.

Fibre optic cable needs some device somewhere to turn it into electrical signals, this needs power, so will be plugged in, and we would hope you can still use the phone when there is a power cut so also some battery to back it up.

I know my friend had it installed, and used the inverter supply from the solar panels so with a DNO supply failure the phone would still work, but it seems the OpenReach cabinet did not have a battery, so with a power cut the phone stops working, and his mobile also will not work.

Not talked to him to find out what OpenReach have done to allow him to even report when he has a power failure.

I can answer that one for you...


Naff all, they are not interested.

Apparently the cabinet doesn't require power to distribute FTTH. For us we don't have full fibre so the cabinet does require power. When I walked past the open cab - which is supplied from a different sub - I mentioned the lack of service during a power cut to the engineer and he quite happily showed the empty spaces where the batteries could go but explained they only fit them if any customer requires service, such as pull cord/pendant assistance etc.

Eh -how does that work? If light goes into the box and electrical signals come out of it, there surely has to be some electronics which require some source.

Are you perhaps merely saying that FTTH does not require mains power, because it has internal batteries that can do the 'powering'?
[ that would be a bit like saying that a cordless drill/vacuum cleaner/telephone/whatever "doesn't require power" ]

What electrical signals?

What electrical signals?

The ones that go to/from your computer and other devices - which I presume don't understand 'light'?

Could be wrong but doesn't the box in your house convert signals from the router (electrical ) to light for the fibre tansmission. So as it has to be independantly powered you supply the electricity.
