This IEEE Standard is part of the C37 Family on Switchgear, Substations & Protective Relays. Project scope: This standard describes the interconnection details for N times 64 kilobit per second connections of teleprotection equipment to digital multiplexers using optical fiber. Requirements for both physical connection and the communications timing are also included. Project purpose: The purpose of this standard is to define an interconnection of different vendors' relays with different vendors' multiplex equipment, without any restriction on the ocntent of the N times 64 kilobit per second data, using up to 2 kilometer of 50 micrometer or 62.5 micrometer multimode fiber.

"Since the technology has moved strongly into a number of different areas a textbook of this sort could be used by a wide variety of academic departments including physics, electrical engineering, mechanical engineering, civil engineering, aerospace engineering and bioengineering. To make the second edition as widely appealing as possible a series of significant upgrades are planned. 1. The book will be structured to support a variety of academic programs 2. Fundamental components and optical concepts will be supported by a new chapter on sensor concepts and upgrades/updates of the chapters on optical fiber, light sources, detectors and modulators. 3. Each of the existing fiber optic sensor chapters will be updated with major upgrades of the fiber etalon and intensity sensor based chapter that will split into two. A new chapter will be introduced on fiber grating sensors and Brillouin distributed sensing. 4. The "application" chapters of the first edition will be updated and new application chapters introduced on fiber biosensors and fiber optic civil structures. The fiber optic smart structure chapter will be extensively rewritten. 5. Questions will be added to the chapters that will serve to support traditional undergraduate and graduate level courses"-- "The book will be structured to support a variety of academic programs"--

"Fiber-optic sensors are a powerful class of sensors, bringing to measurement systems many of the advantages that optical-fiber technology has brought to communications systems. The very high bandwidth of optical fibers allows them to convey a large amount of measurand information through a single fiber. In addition, fiber-optic sensors are intrinsically safe in explosive environments (no sparks), lightweight, compact, robust, and potentially inexpensive. They are therefore useful as sensing devices for a wide range of physical and chemical phenomena that include temperature, pressure, acoustic field, position, rotation, electrical current, liquid level, biochemical composition, and chemical concentration."
