Bandwidth Bottleneck

Infographic: Carl DeTorres Sources: Packet Clearing House; “Internet Traffic Exchange: Market Developments and Policy Challenges,” OECD; Sandvine (Internet traffic breakdown) Click to enlarge. The 2001 collapse of the dot-com and telecommunications bubbles was devastating to the companies laying fiber-optic communications cables. It also had a less-visible impact on that basic optoelectronic physics research that drives improvements in the speed and range of fiber-optic networks. Click on the image for the full illustration view. It takes years for physics innovations to work their way out of the lab and into the market, but the pipeline filled by research in the 1990s dried up by the mid-2000s, and we’re now seeing that the growth in the speed of fiber optic interfaces at Internet exchange points (IXPs) has slowed considerably. IXPs form the core of the Internet, where th...
