Another very basic question.
Where do the copper paths and any fibre cables physically go to get into / out of the NSBFD exchange? * Really basic stuff like what is buried where? * What is fibre and want is Cu?
* I presume there are some EO lines? * I'm wondering what happened to cables immediately exiting the exchange that are heading for a cab?
* Where does the fibre optical cable go (physically) that plays the main role of backhaul ?
Just trying to get a physical picture of where things are what fibre vs what is metallic path and where things are buried ducted etc? How does BT gain access to the conductors and optics in Broadford?
All MPF's (Copper/Ali) are presented on a MDF (Main Distribution Frame). Basically an ironwork frame with labelled blocks to identify the circuit we are working on.
The fibre cables go to a separate part of the building and are presented in lockable cabinets for their engineers to access.
Bothe sets of cables leave all Exchanges the same way ...... through a below ground cable chamber, through the external Exchange man-hole, and then on their way to whatever destination has been planned for them. In urban environment, this will be by ducts with man-holes/joint-boxes at various stages where a mechanical cable joint is required.
In rural environments, and a lot of 1960'70's housing schemes, the cable will be DIG (Direct-In-Ground).
Where do fibre optic cables go ? That's too open-ended to answer, I'm afraid ?? Years ago around my area, they would put various fibre 'Loops' in so that if anyone (normally businesses) wanted fibre BB, they simply tapped into the 'Loop' at the nearest point to the EU.
But I suppose it depends on how near to the Exchange the EU is, the fibre could leave the Exchange and go direct to the premises ?? There's also the fibres that make up the FTTC project.
Both Fibre and MPF go through the same man-holes/joint boxes ............ the fibre cable however will be blown in through a separately installed sub-duct (Basically, a duct within a duct).
Hope this helps in some small way ??
