Fiber Optic Cabling

Barry Elliott, Mike Gilmore9780750650137, 0-7506-5013-3

Fiber Optic Cabling is a practical guide to all aspects of designing, specifying and installing systems for LANs and other data communications applications. The second edition has been completely revised and updated by Barry Elliott, taking into account the major developments in LAN and transmission technology over the past 10 years. The latest legislation is also dealt with, including standards relating to flammability. Cutting edge topics such as photonic switching, wavelength division multiplexing and plastic fiber, and their implications for the future are also explored.An international perspective of the subject is taken, with the author looking at all the practical implementations for fiber optic cabling, using American, European and International ISO standards.
