@ WWWombat,
Thanks for your compliment.
There is no question that this was quite deliberate vandalism.
We also observed BT in the vicinity so they had probably been treated in the same way but could also have had copper stolen.
That really is twin sheathed 16 mm Emtelle Fibreflow™ fibre duct which, in this instance, contained 2 * 192 f cables.
Here's further detail:-
http://www.emtelle.com/experience/b4rn-community-projects-emtelle-fibreflow/You can see the tube has a rifle-type bore to maintain an air vortex to float the cable.
Two new lengths of 192 f cable were inserted.
Indeed B4RN had to add another chamber to accommodate one pair of the new joint bullets.
The other pair were remade in an existing chamber.

More generally I should have mentioned B4RN's significant systems enhancements.
They now have complete dual diversity routes to Internet exchanges down to Manchester / London and up to Edinburgh / Glasgow.
I am no expert in these matters but I suspect B4RN's network is one of the most robust in the UK, once fully completed.
There will be dual diverse routed services to every distribution cabinet all the way back to the two Internet exchanges.
Every property has two individual and separate fibres back to the distribution cabinet, although that part is a single link.
Gigaclear follow a similar design but another major provider seems to put more complicated monopolistic requirements (by sharing a single fibre with up to 32 properties with asymmetric services) over a far simpler design. As a single fibre within a cable only costs £4 per km there can be no financial reason to share the fibre and it must surely complicate any fault-finding operations.
Kind regards,
Walter
