Here is a termination point near us before any customers were

to it - you can see the yellow stripe cable:

That's a joint bullet where one cable is split to two others (in this
case).

Is it run to a DP and then to the properties, same as copper is?
Certainly save digging.


After the split the cables will run to a fibre DP at the top of a
pole or maybe another split. The fibre DPs are black with quite
chunky downward pointing prongs. These are individual fibre ports
fitted with a blanking plug. To connect a customer the blanking plug
is removed and the cable plugged in, the blanking plug then mated
with the cables cap to keep things clean. Fibre cable run to premises
and a fibre connector fitted to plug into the ONT.


Thanks for the explanation. I'll see if it has made any progress next time
I'm passing.


FTTP might not be very good here.


FTTP is one of those things that generally works or doesn't - there is
no practical variability in performance with distance.

We get a steady 37Mbps down 9Mbps up and
that's it on FTTC.


Is that on a 80/20 or 40/10 service? Assuming the latter, it would
indicate you are relatively close to the cabinet (under 1km)

The cabinet is about 3km from the exchange;


That is not the metric that matters - the connection from cabinet to
exchange will be fibre, and not particularly distance sensitive. What
matters is the length of the copper wiring that has to run VDSL from the
cabinet to the end user. So within a few hundred meters it will run flat
out. Over than and it degrades with distance. Once you are over a few
km, then performance will be down in the low single Mbit range, and
probably no better than with ADSL.

I don't know
if that is a factor with fibre.


Fibre does have distance limits - but those are "per segment" so you can
extend by adding another repeater and another segment. So its much
better suited to long runs out into the middle of nowhere.
