not sure i understand your statement, "ready terminated" what does that mean ? , my optical cable is already pulled thru from u/g box and curled up outside my door so not sure im going to be able to run it anywhere 1st !
That will be the external cable, that joins the internal cable in a little grey box on your wall outside.
Like this, i ran the cable from the otherside of the house all the way under the floorboards. You literally see 4 inches of it as it pops up through the floor and into the ONT.
The internal cable is much more flexible and has the ONT end already terminated so if your capably of running that and screwing 1 screw into the wall you can do all the internal work and put it where you like.
