aggregation nodes

In reference to www.thinkbroadband.com/news/8556-baker-s-dozen-of-villages-to-see-l...:

Adapting existing VDSL2 cabinets to utilise spare fibres to link the GPON network back to the aggregation node or handover exchange. This reduces the amount of new spine cabling required.

I'm not actually sure why this wasn't done in the first place where possible. That alone if done for all vdsl2 cabs would have reduce costs from going from vdsl2 to fttp.

Possibly a reluctance to commit the spares to a future use they weren't originally intended for. Yes, it reduces the future capital costs, but it also means reduced ability to cope with expansion of existing facilities or faults therein.

Then, with experience gained over time and changing requirements, it becomes a viable option.

Maybe.

If it was done at the design stage, then your comments wouldn't be true. But yes i do agree with that, you are loosing current redundancy

Also means either further work to do in a few years, or committing to keeping the street furniture with largely redundant DSLAM once VDSL2 is dead

Like hard shoulders on the now far more dangerous �smart� motorways.

How much of the cab structure would be needed and how much could be sunk underground. I would have thought that most of the dslam would go and only the fibre structures would remain? The biggest problem doing this on a reactionary basis, is the lack of redundancy.

Which begs the question whether widespread fttp was ever more than a gleam in someone's eye when the fttc network was being planned... about which I haven't the faintest idea

the idea of smart motorways isn't a bad one, but joe public having to guess what it all means. Smart motorways can create hard shoulders ad-hoc and also on the right hand side too.

Correct. Many didn't see consumers needing > 100mbits. Hdr and 4k/8k changes that.

Depends on how it is all done e.g. is the DSLAM the GPON end point and then uses point to point back to the handover, this is what adds the range extension they are talking about. DSLAM is just a core part with a number of slots for different line cards one of which does GPON FTTP.

OR

Is one fibre split with a passive splitter, for cabinets covering large number of premises this may not work, but in rural areas less of an issue.

Believe current plan is to site the passive splitter option inside the space of the cabinet. Since this is where the spare fibres have been blown too.

Nothing has changed much no on the FTTP front from Openreach for a few years, but these changes are ones that I'll try to get along to and get some pictures of.
