What's next in Broadband

broadband news - Everything You Need to Know About Next-gen Broadband - New DSL flavors, DOCSIS 3.0, Bell TV, and more...
DB: In three to four years - because constructing facilities for millions of people take that long - expect that half of Verizon should have fiber at 15-100 meg, otherwise slow DSL. Half of SBC should have DSL at 10-20Mbps, from existing boxes 2,000-5,000 feet away (FTTN). The rest will be slow DSL and satellite resale. One-tenth of BellSouth customers should have 50Mbps service from fiber to the curb. Half of the rest should have 10-30Mbps DSL, often using two lines...

...DB: Verizon is going as fast as it can building fiber; one newspaper reported 2,000 crews working just in Virginia! It's really that big a job to rewire a third of the U.S. All the others are constrained more by their decision on how much to spend, not construction limits.

Verizon wants fiber to the home. That's the big deal. Three million homes passed by the end of 2005. They've budgeted for, and are likely to deliver - a total of 7 million by the end of 2006 and 15 million by the end of 2008. That's about half of their 1/3rd of the country target - an enormous build costing $15-20 billion. Verizon and NTT in Japan are the only two large carriers in the world doing large volumes of fiber.

Currently, Verizon has a BPON network with video that matches cable on one wavelength and 19 meg down/ 6 meg up. They intend to switch to GPON for new builds as soon as it's ready, and have pushed manufacturers to have equipment by mid-2006 and accelerated the international standard. That's designed for 100 meg symmetric and higher, for real.

For the 20 million plus other Verizon subscribers, they will continue offering DSL and have given no indication they'll jump from the 1-5 meg ADSL speeds to the 10-15 meg ADSL2+. They stopped the DSL build at 80% or so to concentrate on fiber, but I believe are now going back to reach 90%+. Because they were considering selling rural lines, they didn't invest, leaving half of Maine unserved.
Via Slashdot. Back in 1994 this is what we'd thought we'd have by 2000. We were off by quite a bit. One of the reasons the first Internet bubble blew up so dramatically was that broadband deployment was far slower than most analysts projected -- early 1990s business plans that relied on ubiquitous reliable broadband died.

This kind of infrastructure is, I think, closer to what South Korea has now.
