Hi,

I discovered that the Budapest cable company was using VDLS to provide
services up to 500 megs into the buildings where my flats are located. VDSL
is a pretty old standard. I recollect people talking about it back in 1998.

Is it being heavily deployed in Last Mile networks state side?


Hey Rod,
Are you sure they're using VDSL (I'm assuming you mean VDSL2 which is still
in fairly wide use around the world)? 500mbit VDSL2 would have a very short
run limitation afaik. It wouldn't be last mile, more like last meter. :)

It's not super-widely used in the US today since Verizon and others have
built out increasing FTTH networks and always had to compete with DOCSIS
based services which are very widespread here, though I wouldn't be
surprised if it was still frequently the "better than satellite!" service
available in some rural areas that aren't too hard to reach with cabling. A
decade ago, you would've seen a lot more VDSL2 deployments here in the US,
though usually no more than 25 or 50 mbit capacity for the end-user.

https://en.wikipedia.org/wiki/List_of_VDSL_and_VDSL2_deployments has a
bunch of interesting details though I can attest to some of them being
fairly out of date.
