Nightforce Optics

The complete, practical guide to testing fiber optic communication components and systems. Fiber optic networks are evolving rapidly--and so is the technology used to design, measure, and test them. "Fiber Optic Test and Measurement" is the first authoritative, complete guide to measuring both current optical networks and those on the horizon. It reflects the collective experience of Hewlett-Packard's world-class lightwave test and measurement organization, and presents extensive information that has had limited circulation to date. Learn how to characterize all three basic components of a fiber optic communication system: the optical transmitter, fiber medium, and optical receiver. Review each fundamental area of fiber optic measurement, including: Optical power measurements using several types of photodetectors Spectral measurements using diffraction gratings, Michelson interferometers and both heterodyne and homodyne spectrum analysis Polarization measurements--increasingly important in high data rate networks that utilize optical amplifiers Modulation measurements via frequency and time domain analyses The book's unprecedented coverage of advanced fiber technology will be invaluable to professionals implementing or maintaining new optical networks. Learn how to: Test digital fiber systems to SONET/SDH international standards Accurately characterize the behavior of Wavelength Division Multiplexing (WDM) fiber systems Test two-port optical devices for insertion loss, reflectivity of components, chromatic and polarization mode dispersion, and the behavior of Erbium-doped fiber amplifiers (EDFAs). This practical guide will help technicians, engineers, and scientistsaccurately measure and test fiber optic systems, without becoming experts in fiber optic theory. It will be equally useful for experienced fiber optic professionals and those new to the field.

The phenomenal growth in Internet traffic has lead to a huge increase in demand for data transmission capacity on a worldwide level. As a result, wavelength division multiplexing (WDM) technology emerged, which makes it possible to transmit a large number of optical channels on a single optical fiber. An equally significant development occurred in optical networks, where switching and routing of signals takes place in the optical domain. This technology places special demands on the optical sources (lasers) used in the system. This text offers a description of the optical sources (equipment and devices) designed to meet these demands. Sources for DWDM Systems is intended for the engineers and graduate students working on optical networks. There is currently a nearly explosive interest in optical networks and the components required for such networks, but there is presently no single work which covers the variety of optical sources which may be used. This book will cover a particular component, tunable lasers, which is the next "big thing" in DWDM. The primary market are engineers developing tuneable lasers for optical networks, as well as graduate students enrolled in the optical engineering curriculum, especially: optical communication, semiconductor lasers, optical networks, and/or components for optical networks.

Physical optics - Physical optics, or wave optics, is used in physics to refer to the branch of optics which studies interference, diffraction, polarization, and other phenomena for which the ray approximation of geometric optics is not valid. This usage tends not to include effects such as quantum noise in optical communication.

Thin-film optics - Thin-film optics is the branch of optics which deals with very thin structured layers of different materials. In order to exhibit thin-film optics, the thickness of the layers of material must be on the order of the wavelengths of visible light (about 500 nm).

Non-imaging optics - Non-imaging optics is the branch of optics concerned with the optimal transfer of light between a source and a target. Unlike traditional imaging optics, the techniques involved do not attempt to form an image of the source; instead the maximal illumination of the target by the light from the source is desired.

Crystal optics - Crystal optics is the branch of optics that describes the behaviour of light in anisotropic media, that is, media (such as crystals) in which light behaves differently depending on which direction the light is propagating. Crystals are often naturally anisotropic, and in some media (such as liquid crystals) it is possible to induce anisotropy by applying e.
