31、iber Specifications. NOTE - This Specification was previously published as part of EIA-4928000. 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 Ge
32、neric Specification, TIA/EIA-4920000-B, is the umbrella document for all optical fiber 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
33、targeted toward various applications, and to specific groups of fiber designs. - Sectional 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 re
34、ference the Generic Specification, extracting requirements applicable to the fiber family. 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 ar
35、e prepared for a limited series of fiber subfamilies that fall within the family of the 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 Specifica
36、tions follow the applicable Blank Detail Specification and provide detailed requirements 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
37、Specifications may be written by TIA Working Groups or by manufacturers. Some attributes that are normally expected to vary among purchases (e. g., length) may be delegated to the procurement document.

40、etting forth engineering and use requirements as necessary for purchase of Class IVa dispersion-unshifted single-mode 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 p
41、rocedures. 1 Scope This Specification applies to Class IVa dispersion-unshifted single-mode optical fibers with glass core and cladding. Class IVa fibers are typically used in telecommunications, video, and data applications. This Specification, Basic specification EIAITIA-455-A and its addenda, Gen
42、eric Specification TIA/EIA-4920000-B, Blank Detail Specifications, and all Detail Specifications derived from the first four listed Specifications shall follow the specification structure used in the U.S. National Electronic Components Quality Assessment System (NECQ). For further details, see the F
43、oreword. 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 invitation for bids or requests for proposals, form part of this Specification to the extent specified herein: 1 STD-E

This includes all documents referenced in 2.1 (TINEIA-4920000-B is called the “Generic Specification“ throughout this document). EIA/TiA-455-A, Standard test procedures for fiber op
45、tic fibers, cables, transducers, sensors, connecting and terminating devices, and other fiber optic components. Each Fiber Optic Test Procedure (FOTP) is a separate addendum to EIAIA-455, and each is designated by the FOTP number, as the “XX“ in EIAlTIA-455-XX. 3 Background information 3.1 Object Th
46、e 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 prescribing required attributes and their preferred values or characte
47、ristics, 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 for preparation of Detail Specifications. The minimum list of specifi
48、ed attributes will be included in the Blank Detail Specification. The preferred values prescribed in this Sectional Specification may also be repeated in the Blank Detail Specification if it is practical to do so. A Blank Detail Specification is required for each subclass of dispersion-unshifted sin
49、gle-mode 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 characteristics. 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 may be le
