After reviewing EMI and related problems in conventional wire coupling and common solution, the book opens with optical coupling as an alternative solution. After surveying the sources and detectors of optical coupling, and the solutions of radiation, cross-talk and ground- related problems, the limitations of optical coupling are discussed.
Optical isolators in circuits and systems are presented, together with testing and device selection. Fiber optic media and some basics of optical fibers and cable preparation are covered. Connectors and couplers are addressed separately and as a unit.
Digital fiber-optic links covering the transmitters, receivers, repeaters and optic buses are reviewed. Analog fiber-optic links and their limitations are also surveyed with applications to audio and video channels and trunks.
Selection criteria starts with overall system considerations and moves to the components, modules and devices selection. The subject is closed with packaging assemblies and compatibility's.
Applications to industrial controls and methods of measuring transmission characteristics are presented. Hardened fiber-optic links including EMI environments are also surveyed.
