Wow what a lot of questions as others have said it depends where you live as VM is made up of differrent cable companys all built there network to there own specs .Some telephone system use SDH and some PDH .Is this area the fibre goes out to the street to a control cab where it is changed over to copper which then goes to other cabs in the street which then goes to your house .Some towns have a Headend and some towns have a Hub site which is fed from the headend .
We have a local channel here and they send us the feed on fibre to the headend where we put it onto the network on analouge and digital
How many homes can be fed of a Fibre cab depends on the network build in the area
