Gigabit-capable Passive Optical Networks

Gigabit-capable passive optical networks (G-PON) have a large and increasing base of support among telecommunications operators around the world. Written by two of the experts in the field, this book explains G-PON in detail, both the original 2.5 Gb/s version and XG-PON, the 10 Gb/s second generation. The foundation established by this book is also invaluable in understanding NG2 (next-generation 2) G-PON, which is built upon a number of XG-PON systems on parallel wavelengths. As well as a history that clarifies the reasons for many of the existing features, the book looks at current and evolving technology and discusses some of the alternatives for future access networks.

About the Author :
DAVE HOOD is a Senior Systems Engineer at Ericsson AB. He has been involved with passive optical networks since they were first conceived in the 1980s. He is presently active in the FSAN and ITU communities, where, among other responsibilities, he serves as editor of OMCI Recommendation G.988. ELMAR TROJER is a Senior Systems Engineer at Ericsson AB, where he has developed dynamic line management solutions for ADSL2+ and VDSL2 and prototyped the DSL automatic optimizer that became an Ericsson product. He also prototyped the world's first Gb/s passive optical network system.
