At present, there is a strong worldwide push toward bringing fiber closer to indi-
vidual homes and businesses. Fiber-to-the-Home/Business (FTTH/B) or close to it
networks are poised to become the next major success story for optical fiber com-
munications. In fact, FTTH connections are currently experiencing double-digit or
even higher growth rates, e.g., in the United States the annual growth rate was 112%
between September 2006 and September 2007, and their presence can add value of
U.S. $4,000–15,000 to the selling price of a home.
We were on the lookout for ice.
I was in a 32 foot sailing yacht with writer and explorer Tristan Gooley, undertaking a
double-handed sail from Scotland through the Faroes up to 66 33 45.7 N and the midnight
sun. Now sailing out of the Arctic Circle we were approaching Iceland from the north, heading
for the Denmark Straits, where ice flowed south. The Admiralty Pilot warned of bergs but the
ice charts we had sailed with were over a week old. We needed an update.
This book is based on a Ph.D. research that has been conducted at the Delft
University of Technology in the Netherlands in collaboration with Dutch Electricity
& Gas Distribution Network Operator, Stedin. This book was written as a result of
wider interest that was shown by different industry groups on this topic after its
public defence. This inspired the author to modify and publish a practical version
of the research for a greater international audience. Therefore, the content of this
book is intended for a double audience, on the one hand for those interested in the
organisational and management aspects of maintenance.
