Fiber Optic Test and Measurement by Dennis Derickson,

Fiber Optic Test and Measurement by Dennis Derickson,
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.

Very high frequency - Very high frequency (VHF) is the radio frequency range from 30 MHz (wavelength 10 m) to 300 MHz (wavelength 1 m). Frequencies immediately below VHF is HF, and the next higher frequencies are known as Ultra high frequency (UHF).

Ultra high frequency - Ultra high frequency (UHF) designates a range (band) of electromagnetic waves whose frequency is between 300 MHz (Wavelength 1 meter) and 3.0 GHz (Wavelength 10 centimetres) .

Cutoff wavelength - In fiber optics, the cutoff wavelength for a mode in an optical fiber or waveguide is the longest wavelength for which that mode can propagate. For single-mode optical fiber, the cutoff wavelength is approximately the wavelength at which the normalized frequency is equal to 2.

Radio frequency engineering - Radio frequency engineering is the analysis and design of circuits at frequencies where transmission lines are comparable to the wavelength. It includes the study of amplifiers, oscillators, mixers, demodulators (including PLLs) and antennas.
