Oh they have, in fact my provider used the existing tube which is used for electricity, phone and anything else.
In many areas, that would be illegal. Power and copper signal cables must be separate for safety reasons. No problem with fibre though. Also, it's often very difficult to run new cables into a conduit that already has cables. With phone cables in an apartment building etc., you'll find multi-pair cables running vertically in conduits, from floor to floor, appearing in a utility box in the wall, where individual pairs can be connected to. A 25 pair cable is about as big as your finger, and 50 pair a bit bigger than your thumb. There's no way you're going to get 25 or 50 ethernet cables in anywhere near the same space.
UTP has a maximum usable distance of 100M. This means you'll need lots
of repeaters for lots of cables to deliver ethernet. Yes but you connect not just one building but lots of them.
Are you suggesting they have repeaters in every building? Even so, you're still limited to 100M between bridges or switches. Carriers in Canada are gradually installing "fibre to curb", which brings fibre into the local neighbourhood. But they are most certainly not running cat5 or cat6 building to building to cover the distance from the central office. As I mentioned in another note, my building is over 100M from the road and the utility room is even further back, at the opposite end from the road. Ethernet over UTP simply won't go that far.
How can one provide Internet to a building over one coax (even if it exist?) I even do not know if there is any cable television here. I have only ether channels, although they expanded the number greatly last year (which may indicate they layed cable TV cable). There is also a commercial cable TV provider here who is notorious for advertising by telephone calls, they have a separate net and advertise cable TV and Internet, but they for sure layed their network themselves from start.
Internet over the cable TV network has been common in Canada and elsewhere for many years. I first connected to it about 11-12 years ago. Here's a link to some info on the technology used: http://en.wikipedia.org/wiki/Docsis For many years, the cable networks here have been capable of carrying data in both directions. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
