NOTE - This Specification was previously published as EI
29、A-492A000. This Specification forms a part of a set of TINEIA standards that systematically specifies performance requirements for optical fiber. This hierarchical specification system comprises four tiers: - The Generic Specification, TIA/EIA-4920000-B, is the umbrella document for all optical fibe
30、r specifications. It delineates minimum requirements that are common to all optical fiber types, as well as providing a “shopping list“ of test requirements and test methods that may be applied to families of fiber targeted toward various applications, and to specific groups of fiber designs. - Sect
31、ional Specifications define requirements for fiber families, ordered by primary design (e. g., multimode, single-mode). They set forth requirements applicable to all fibers in the family. Sectional Specifications reference the Generic Specification, extracting requirements applicable to the fiber fa
32、mily. They may introduce other requirements that are not addressed in the Generic Specification. Values for most requirements are delegated specifically to the Detail Specifications. - Blank Detail Specifications are prepared for a limited series of fiber subfamilies that fall within the family of t
33、he relevant Sectional Specification. They give specific directions for writing Detail Specifications and may introduce additional requirements that are not addressed in the higher-order documents. - Detail Specifications follow the applicable Blank Detail Specification and provide detailed requireme
34、nts for specific applications. They also may introduce additional requirements not addressed in the higher-order documents. Values for primary performance requirements are given in the Detail Specifications. Detail Specifications may be written by TIA Working Groups or by manufacturers. Some attribu
35、tes that are normally expected to vary among purchases (e. g., length) may be delegated to the procurement document. The procurement document references the applicable Detail Specification. . 111 Previous page is blank STD-EIA TIA-472A000-A-ENGL 1797 323Lib00 0588011 3TB For additional information o

37、881332 234 m TINEIA-492A000-A Sectional Specification for class la graded-index multimode optical fibers Introduction This Specification was formulated for the purpose of providing a document setting forth engineering and use requirements as necessary for purchase of Class la graded-index multimode
38、optical fibers. Use of this document is intended to eliminate misunderstandings or confusion between the supplier and user with respect to product performance requirements and test procedures. 1 Scope This Specification applies to Class la graded-index, multimode optical fibers with glass core and c
39、ladding. These fibers are defined as having a refractive index profile which varies with radius from the center of the core and has a profile parameter, g, whose value is 3 g 1. Class la fibers are used in long-haul telecommunications links with moderate bit-rates, and in short-length links for data
40、 communications and local area networks. This Specification, Basic Specification EIA/TIA-455-A and its addenda, Generic Specification TIA/EIA-4920000-B, Blank Detail Specifications, and all Detail Specifications derived from the first four listed Specifications shall follow the specification structu
41、re used in the U.S. National Electronic Components Quality Assessment System (NECQ). For further details, see the Foreword. 2 Normative references The latest published revisions, addendums, and notices for the issue of the following documents in effect on the date of use of this Specification in inv
42、itation for bids or requests for proposals, form part of this Specification to the extent specified herein: 1 TINE IA-492A000-A TIA/EIA-4920000-B, Generic Specification for optical fibers. This includes all documents referenced in 2.1 (TINEIA-4920000-B is called the “Generic Specification“ throughou
43、t this document). EIAiTIA-455-A, Standard test procedures for fiber optic fibers, cables, transducers, sensors, connecting and terminating devices, and other fiber optic components. Each Fiber Optic Test Procedure (FOTP) is a separate addendum to ElmIA-455, and each is designated by the FOTP number,
44、 as the “XX“ in EIAiTIA-455-XX. 3 Background information 3.1 Object The object of this Specification is to define requirements of product, testing, and specification documents, in order to assist those who prepare Detail Specifications based on this document. This object is carried out, in part, by
45、prescribing required attributes and their preferred values or characteristics, and in selecting from the Generic Specification the appropriate Quality Assessment procedures, tests, and measurement methods. Derive one or more Blank Detail Specifications from this document to serve as a practical form
46、 for preparation of Detail Specifications. The minimum list of specified attributes will be included in the Blank Detail Specification. The preferred values prescribed in this Specification may also be repeated in the Blank Detail Specification if it is practical to do so. A Blank Detail Specificati
47、on is required for each subclass of graded-index multimode fiber, as appropriate. Requirements that are specific to a subclass may be found in a Blank Detail Specification. Clause 4 specifies the attributes that shall be specified in a derived Detail Specification, along with preferred values and ch
48、aracteristics. Clause 5 describes the Quality Assessment procedures and includes qualification approval and Quality Conformance Inspection (QCI) requirements. Clause 6 outlines the recommended tests and measurements. This Specification also indicates which test options and performance requirements m
49、ay be left to the Detail Specification writer. 2 STD-EIA TIA-492A000-A-ENGL 1997 D 3234b00 0.588014 007 TINE IA-492A000-A 3.2 Information to be given in a Detail Specification Derive each Detail Specification from the applicable Blank Detail Specification.
