So how is the fibre actually run from the exchange if the cab isn't touched? I'm not exactly clued up on Openreach's PON infrastructure design.

the fibre is run underground in ducts or on overhead poles. Any FTTP hardware goes on telegraph poles or in underground chambers.

All that's in the cabinet is a bunch of copper wires. These are left as they are when FTTP is rolled out.
They never need to touch the cabinet when installing FTTP, they never run fibre through the cabinet and they never install FTTP hardware in the cabinet.

The fibre from exchanges runs to underground chambers containing "Aggregation Nodes" which AIUI (can) have several outputs to further aggregation nodes so branching out in a tree structure.

FTTC cabinets are fed from a suitable aggregation point for the target PCP (phone cabinet). FTTP and FTTPoD are also fed direct from aggregation points to splitters and "close-to-premises" Distribution Points.

The PCPs are a completely different network all running on copper from the exchange. For FTTC the new fibre cabinet and its PCP have a short underground link where the phone signal is diverted to the FTTC to be merged or de-merged with/from the VDSL2 the FTTC cabinet DSLAM converts to VDSL2 to you or fibre optics back to the exchange.

The merged signal of phone and VDSL2 goes back to the PCP and connects to the line to your premises. And vice versa.

Looks like Birds Farm in School Lane (which I think is Elmstead) and some properties in Cockaynes Lane and Colchester Main Road were connected to FTTP last June so these would have been well ahead of the December 2019 deadline set for them.

In addition to the answers already given, there's a training video here which lets you see what an aggregation node and a splitter node actually look like.

Hi

Rather than create a new thread, something new has popped up against our ECI cabinet on roadworks.org, described as:

MJ Quinns are to install a new DSLAM cabinet and run approx. 20m of ducting and build a side pod onto existing BT cabinet.

So not sure what that is exactly, perhaps the cab is full or near to full (nothing to suggest actually full on the dslchecker) so they may be adding extra capacity, I'm not aware we are due G.Fast as nothing announced for where I am.

Phil

All the hall marks of adding additional capacity

This not a G.fast. It's additional capacity.

Hi

Many thanks, didn't want it to be G.Fast, as not many people benefit from the extra speed, I certainly wouldn't as too far away, plus potentially delays any eventual FTTP.

Regards

Phil

Nor me too. I don't want G.Fast cos I rather to wait for FTTP to come but I think Openreach are likely to bring in G.Fast for many of Telford area later this year.
