DSL still makes up 35 percent of fixed broadband subscriptions across OECD countries but high-speed fiber is continuing to make steady progress. The OECD has reported that the share of fiber connections has now grown to 26.8 percent, up from 12 percent nine years ago. Ireland saw the highest growth in fiber connections with an increase of 532 percent in two years with Belgium (192 percent) and the UK following (144 percent).
There are considerable differences in the share of fiber broadband connections between countries and South Korea came first with 81.7 percent in Q2 2019, just ahead of Japan's 79 percent. Even though the United States has a lot of work to do in order to catch up with 15.6 percent, it's still ahead of Italy (6.0 percent), Germany (3.6 percent) and the United Kingdom (2.3 percent)
