Diese überarbeitete Neuauflage erläutert den technologischen Fortschritt auf dem Gebiet der erbiumdotierten Faserverstärker, einer wichtigen Technologie für Sprach-, Daten- und Kabelfernsehübertragungen.
- Faserverstärker-Boostermodule in land- oder seegestützten Langstrecken-Telekommunikationssystemen erlauben es, ein Signal über größere Entfernungen mit größerer Sicherheit zu übertragen.
- Repeater brauchen nur in größeren Abständen eingesetzt zu werden, was den Systementwurf vereinfacht
- das Telekommunikationsgesetz von 1996 hat die geographischen Grenzen im Telekommunikationsmarkt beseitigt und die weltweite Deregulierung initiiert; seitdem ist das Internet stark gewachsen, und es entstand ein immenser Bedarf an erweiterter Bandbreite auf allen Netzwerkschichten
- der Hauptteil hierfür wird von terrestrischen und Unterseekabeln zur Verfügung gestellt, die sich auf faseroptische Technologien stützen
- der Autor leistete selbst wichtige Beiträge zur Unterwasserübertragung

EMMANUEL DESURVIRE has been involved in the field of optical fiber amplifiers for nearly twenty years, starting with his PhD work on Raman fiber amplification in 1981-83. For his contributions to the early investigation and development of EDFAs at AT&T Bell Laboratories, he received several national and international awards, including the 1994 prize from the International Commission for Optics and, jointly with Professor D. N. Payne, the 1998 Benjamin Franklin Medal in engineering. He is currently Director of the Alcatel Technical Academy, a corporate program that aims to recognize experts and foster synergies in research and development. An IEEE Fellow, he has authored or coauthored more than 200 technical publications and 30 patents.
DOMINIQUE BAYART graduated as Physics Engineer from the National Polytechnic Institute of Grenoble (France) in 1990. He joined Alcatel Research and Innovation (Marcoussis, France) in 1991 and is now Deputy Manager for the Photonic Transmission Unit. He has contributed 12 postdeadline papers to major conferences (OFC, ECOC, OAA) and authored or coauthored more than 70 technical publications and 30 patents.
BERTRAND DESTHIEUX received an MS in physics from Limoges University, France, and graduated as an engineer from Orsay's École Supérieure d'Optique in 1990. He is a former team leader at the Alcatel Transmission System Division in Nozay, France. After Alcatel, he joined Latus Lightworks in Richardson, Texas, as manager of the optical transmission engineering department. He is now a senior engineer in the photonic department at Xtera Communications, Inc., in Allen, Texas. He has authored or coauthored nearly 20 technical publications and 15 patents.
SÉBASTIEN BIGO received an engineering degree from the École Supérieure d'Optique in 1992 (Orsay, France) and a PhD from the University of Besançon (France) in 1996. He is the leader of the WDM transmission group at Alcatel Research and Innovation, which obtained several multi-terabit/s transmission records, and has authored or coauthored more than 80 papers and 25 patents.
