Optical Fiber Transmission Paul Urquhart
Pages 74

Optical fi ber communication provides data capacities that are unavailable from any other transmission means, and so it exerts a substantial infl uence on the information society (Hecht, 1999). Optical cables have been installed in many environments-within buildings, under streets, suspended from overhead pylons, and across the world’s deepest oceans (Urquhart, 2004; Keiser, 2006; Lin, 2006; Halabi, 2003; Chesnoy, 2002). The networks they serve carry data for many end users, including domestic consumers, manufacturing, fi nancial services, hospitals, educational establishments, and government departments. The history of the subject is one of record-breaking achievements, especially as measured by distance, total capacity, and number of customers served.
