The other thing you describe is a fibre joint, not always on a pole below a CBT.

One less fibre joint has got to be a good thing.

The only thing on the top of the pole thats new is *similar * to this (it might have more ports)

BTW I think the image name ("connectorised-splitter.jpg") is wrong, as it's not a splitter. A 4-port CBT has has 4 fibres coming into it, one for each port. The splitter will be upstream somewhere.

Some of the Openreach diagrams available on the web indicate they were initially looking at doing 2 level splitting when they first launched CBT's (the second split being in the CBT) but from what Zarjaz has stated on here it was never rolled out.

Edit: The split ratio at the CBT would have been 1:4 so 1 fibre for every 4 ports and at the primary splitter the ratio would have been 1:8 so 1 fibre split 8 ways

As we are talking about CBT's I have a question

Do they always connect all CBT ports to the splitter? for example the smallest CBT is 4 port and its on a rural pole that can only ever service 1 property do Openreach still connect all 4 ports or only 1 port? If they don't connect all ports is there a standard way these are marked to show they are not connected to the splitter?

Nope, not all are connected, the same as for copper DP’s.

Thanks, so no visual check (e.g. marked in some way) to determine how many are connected through?

I'd have thought the cable would carry at least 4 strands - so if somebody else did order service, they'd just have to splice it onto a spare splitter port.

Nope, just held on records.

My fibre poles were erected on the 1/10/19

on the 16/10/19 I got this update.

Poles are up but we need to lay 100m duct in soft to create a shunt below 110KV power. Estimated required by date for this work will be about 4 weeks or around the middle of November. DRD (I am checking on this with BT) Permits to work are required.

It's interesting just seeing how long all these things take.

Another update on my build.. getting ever closer it seems

"This order only started the commissioning process on 15/10. This means that the external build has completed.
Please note Commissioning can take 2-3 weeks depending on the results of the audit and if any defects are reported.
Once the commissioning/auditing is completed successfully the final internal visit will be booked. "

Hope the "audit" results in no issues.
