G.fast - why the pod?


[link to this post]
 
Hi,

Our of interest, does anyone know why G.fast is installed as a pod on the PCP cabinet, rather than just a different type of line card in the FTTC cabinet?

First guess .... not enough copper link capacity between DSLAM and PCP ?

Second guess, ... the fibre goes elsewhere ?

Third guess ... trying to reduce near end cross talk ?

And another one - it makes the copper line to the premises shorter if it doesn't go via the FTTC cab. A few metres makes a big difference with G.Fast.smile

Reducing crosstalk and length of cables makes sense.

Maybe also reduces the number of junctions?

This. No line card for the existing kit.

But why not put the Pod on the DSLAM Cabinet, which already has the fibre termination in it?

I think the cabinets are usually pretty full. They may also not have appropriate racking (or whatever) to support the additional hardware. I suspect if BT could do it then they would as adding additional pods will cost more.

As already said: line length.

My fibre cabinet is about 80m away from the PCP. This is admittedly quite extreme: but if they were ever to deploy G.fast here, putting it on the fibre cabinet would burn a good chunk of the link budget.
