OK, so that's one question answered .... but what of the kit that fits the connectorised end on said cable ?

I am thinking its either glued on, or if they are metal connectors they could be thermally connected.

Hard to tell without any images so I am probably wrong in both counts LOL

Those modular connections do look cool though.

So in a location where at the moment there is no ducting, just poles carrying copper wires to a group of properties which are currently connected to an FTTC enabled cabinet.

If BTO are going to install FTTP, where would that large Aggregation Node go? On a pole or ? This is to supply about 60 properties.

The Aggregation Node will probably be down the road or could also be outside the actual exchange, but normally are in one of BT's chambers, the fibre cable then leave that chamber and can possibly then use over head cables from pole to pole connecting to Splitter Nodes.

The Splitter Node on the other hand are normally in the chamber near the are it supports, the DP's can be located in the chambers near the phone poles, or the DP's can be mounted on the actual phone poles.

TBH I have only seen Aggregation and Splitter Nodes and DP's all located in the chambers, so I cannot really say for sure.

*** update ***
Basically my understanding was that the fibre leaves the exchange and goes into the Aggregation Nodes that are daisy chained, each of those Aggregation Nodes supplies fibres to a few Splitter Nodes that are also daisy chained, and each of those Splitter Nodes supply fibres for the Fibre DP's which are also daisy chained each supplying up to 12 fibres for 12 homes.

Thank you, that is what I have seen too.

The only chamber and cabinets which exist are immediately next to the exchange, there are no other ducts or chambers, all the wires go over poles to those 60 properties. The first property we plan for FTTP is about 900m from the exchange with the last being +4km away, all properties are dotted along one long lane with little or no room for any cabinets to be built, the lane has stone walls or buildings marking the road. If this CFP with BT goes ahead it will be interesting to see how those problems are solved.

That answers my question, I always wondered if some form of mechanical splicing was possible. Still quite fiddly but presumably requires a less skilled engineer than fusion splicing.

I assume the db loss is greater than fusion splicing so they still fusion splice at the SPN?

So in summary connectorisation means two less fusion splices (DP & CSP) and probably a less skilled engineer, hence the cost savings compared with the previous deployment method.

Just answered my own question http://www.fiber-optic-solutions.com/mechanical-spli...

0.3db loss mechanical vs 0.1 db loss fusion, and the mechanical splice is quite a bit more expensive.

Yes, that's precisely why they've changed over (or are in the process of changing over) to doing this method.

There's a video where Neil McRae describes some of the changes & reasoning:
