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.

Optical amplifier - In optics, an optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal, then amplify it electrically, and finally reconvert it to an optical signal. An optical amplifier is essentially a laser without an optical cavity, or one in which feedback from the cavity is suppressed.

Optical waveguide - An optical waveguide is a form of a dielectric waveguide that is capable of guiding an optical signal. The optical waveguide can be used as an component in integrated optical circuits or as a transmission medium in local or long haul optical communication systems.

Optical burst switching - Optical burst switching OBS is a switching concept which lies between optical circuit switching and optical packet switching. Firstly, a dynamic optical network is provided by the interconnection of optical cross connects.

Passive optical network - A Passive Optical Network (PON) is a fiber to the premises configuration in which unpowered optical splitters are used to enable a single optical fiber to serve multiple premises, typically 32. A PON consists of an Optical Line Termination (OLT) at the communication company's office and a number of Optical Network Units (ONUs) near end users.
