Over a decade later since the telecom bust in the late 1990s and early 2000s, the excess network capacity has been abandoned, obsoleted, or more than used up. Telecoms have long since begun building new capacity – much more cautiously this time, using new technology – DWDM and ROADMs largely. Traffic now is growing continuously (at 40% a year) but capacity is growing much slower due to the caution from the bitter 2000 experience, and due to the worldwide recession. This combination could be leading to a reversal of the 2000 situation, but potentially just as dangerous – a new telecom BUST created by poor service on what are now very critical telecom links resulting from under capacity.
