Twenty years have passed since the first serious proposal was made to employ a glass fiber waveguide as a telecommunications transmission medium.
Lasers emitting near 1.3 and 1.55microns, fabricated using the InGaAsP material system are widely used in many commercial lightwave transmission systems.
Summary form only given. The erbium-doped optical amplifier moved very quickly from invention in 1987 to the cornerstone of high speed long-haul networks.
In the mid 1970's a set of studies of rain attenuation on line- of-sight microwave radio links was undertaken by a number of organizations of Bell Laboratories.
Digital radio often requires performance improvement beyond that afforded by frequency diversity. Traditionally, this improvement has been obtained through space diversity.
In this book, we talk about echo cancellation in general. We develop several new ideas for network, multi-channel acoustic echo cancellation, double-talk detection, and adaptive filtering.
Routing is a central topic in networking since it determines the connectivity between users.

A fiber-optic sensor system (FOSS) consists of an optoelectronic hub, optical fibers, and an optical sensor or sensor network.
Amplified electro-absorption modulators provide a realistic solution for colorless 10 Gb/s uncooled ONUs.
