TIA TIA-526 PDF

INTRODUCTION

This document, together with its addenda, provides uniform test procedures for testing all or part of fiber optic systems or subsystems intended for optical communications and data transmission use. In testing an installed system, the testing organization will usually have little or no control over the environment which each component of the system will be experiencing; consequently, when the procedures covered by this document and its addenda are used for acceptance testing of a particular system, the results shall be evaluated with the understanding that all system components might not be at the standard conditions at which they were originally tested and accepted. When a system is being tested as a representative of other systems not yet built, environmental conditions shall, however, be as close to the standard ambient conditions listed in Section 6 as is practicable.

Neither this document, nor its addenda, provide procedures designed for testing fiber optic components intended for, or forming a part of, optical communications and data transmission systems. For test procedures for fiber optic components, refer to the TIA/EIA-455 series of documents.

The test procedures included in the addenda to this document are designed to satisfy the broadest possible industry requirements; in general, special test methods are not included. In order to adequately cover these broad industry needs, many of the addenda require that some "option designator," some test parameter definition, andor some pasdfail criteria shall also be specified whenever the addendum is called out. Only in special cases (such as specified DoD requirements) are special test details listed in the addendum in addition to the general requirements. Specific test requirements (including DoD requirements) can, of course, be modified by direction of the Detail Specification so that the particular test can accurately reflect the special test needs (more or less severe than standard) of the system or subsystem in question. In the event of conflict between the provisions of these test procedures and those of the Detail Specification, the requirements of the Detail Specification shall govern.

In the terminology of IEC Guide 102 and of EIA EP-11, this document, together with its addenda, is considered to be a Basic Specification.
