Krzysztof Perlicki ISBN: 978-83-206-1646-0 format B5, p. 256, fig. 182, tab. 58, hardcover Price: PLN 40.00 Academic handbook on the technique of multiplication in the field of wavelength (WDM), which is one of the basic modern telecommunications techniques, enabling the implementation of very high bandwidth transmission, used in long-range systems and access networks. WDM systems architecture, physical phenomena affecting performance and abuse in WDM systems, as well as standardization and layered model as well as design and practical implementations as well as WDM systems testing methods have been described. A handbook for students of electronics, telecommunications and related fields, post-graduate students and for people who, due to their profession, have direct contact with modern telecommunications systems.
