ASTM E1653-94(2004)

Many characteristics of a fiber-optic waveguide affect the dynamic performance. Quantitative values of certain key parameters (characteristics) need to be known, a priori, in order to predict or evaluate the dynamic performance of a waveguide for specific conditions of use. This guide identifies these key parameters and provides information on their significance and how they affect performance. However, this guide does not describe how the needed quantitative information is to be obtained. Manufacturers of fiber-optic waveguides can use this guide for characterizing their products suitably for users who are concerned with dynamic performance. Users of fiber-optic waveguides can use this guide to determine that their waveguides are adequately characterized for their intended application.

1.1 This guide covers the key parameters that determine the dynamic performance of an optical radiation transmitting fiber waveguide (see Note 1). For the purpose of this guide, optical radiation is electromagnetic radiation of wavelengths from about 200 to about 5000 nm (correspondingly, frequencies of 50000 cm -1 to 2000 cm -1 , and photon energies of 6 eV to 0.25 eV).

Note 1--Typical designations of radiation transmitting fiber waveguides include optical waveguide, fiber-optic, fiber-optic waveguide, and fiber-optic radiation guide.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
