3、tween manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for his particular need. Existence of such Standards and Publications shall not in any respect preclude any me
4、mber or nonmember of WEM from manufacturing or selling prudu 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, and/or some passfiail criteria to be sp
5、ecified whenever the addendum is called out. Only in special cases (such as specified Do 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 Deta
6、il Specification so that the particular test can accurately reflect the special test needs (more or less severe than standard) of the component 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
7、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. 2 Normative references The following publications contain provisions which, through reference in this text, may constitute provision
8、s of this Standard. At the time of publication, the editions indicated were valid. All publications are subject to revision, and parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the publications indicated below.

Each individual procedure is identified as an “FOTP“ (for Eiber Optic Lest - Procedure), fo
16、llowed by a numeric identifying number (e.g., FOTP-1 , FOTP-20), and this FOTP number is never changed as long as the procedure remains in force. Each individual addendum is assigned a number which is the same as the FOTP number assigned to that procedure. When an addendum is revised, a character is
17、 added following the FOTP dash number to indicate the revision level of that particular addendum. For example: FOTP-39 appeared first as TINEIA-39 The first revision appears as TINEIA-455-39A The second revision will be TINEIA-455-39B NOTE - There is no such thing as “FOTP-39A,“ but there is an adde
18、ndum identified as -455-39A. 3 Copyright Electronic Industries Alliance Provided by IHS under license with EIANot for ResaleNo reproduction or networking permitted without license from IHS-,-,-TINEIA-455-B 4 Application These test procedures have been and are being developed by the various subcommit
19、tees and working groups of TIA Engineering Committee FO-6, and are approved for use jointly by EIA and TIA. Individual component design standards (Detail Specifications) incorporate these standard test procedures to preclude variations in the results that are used to determine if requirements have b
20、een attained. The procedures standardize the methods of establishing such measurements as attenuation and insertion loss for the purpose of establishing conformance to individual component requirements. Unless otherwise indicated, the procedures are generally applicable to both single fiber and mult
21、iple fiber component designs. By appropriate direction of the applicable Detail Specification, the test procedures of the published FOTPs may be modified to suit special needs. 4.1 Criteria for FOTPs A fiber optic test procedure (FOTP) is a test or measurement of an attribute that may be specified o
22、n individual components. Before a committee adopts an FOTP, it should determine that: - The attribute is important to the functional use of the component. - The test or measurement procedure is capable of reasonably consistent interpretation. - The test or measurement procedure is sufficiently repro
23、ducible in the context of the expected requirements. When a test or attribute is perceived to have value beyond component specification yet does not satisfy the above requirements, an informative test method (ITM) following the TSB-62 guideline may be considered. An ITM can be written for some of th
24、e following reasons (see TSM-5-A): - The parameter may not be considered useful because the performance of the product does not necessarily depend on it, or because there is another parameter that is more appropriate. 4 Copyright Electronic Industries Alliance Provided by IHS under license with EIAN

26、sign phase of a fiber-optic component, but other parameters are better measures of the performance of the end product. - The parameter might be considered useful, but round robins using the particular test have not demonstrated an agreement among measurement facilities. 4.2 Multiple test methods In
27、some cases, multiple test methods are considered equivalent for the measurement of a given attribute. When there are multiple methods for an attribute, the following actions are recommended: - Consolidate the methods into one FOTP. - Designate one of the methods as the Reference Test Method (RTM) fo
28、r use in resolving disputes. Take the following into consideration when choosing a specific RTM: - The degree to which the method relates to the definition of the attribute. - The accuracy of the (calibrated) method - The reproducibility (both precision and interlab) of the method. - Practical use o
29、f the method. - Harmonization with international standards Note: The RTM need not be the method that is used to generate cal i bration artifacts. If needed, a procedure from Annex B may be used to establish the empirical equivalence of measurement methods. 5 Copyright Electronic Industries Alliance

38、 for either standard or controlled ambient, unless otherwise specified. 7 Metric policy for FOTPs The primary measurement system for fiber optics is the modernized metric system, known as the International System of Units (hereinafter referred to as “SI“), All units stated in FOTPs shall be expresse
39、d primarily in SI terms. In consideration of various factors, however, it is the policy of TIA Committee F-6 that units of measure in the “U.S. Customary“ or inch-pound system shall parenthetically follow the metric units. In the preparation and publication of FOTPs, this general policy shall be int
40、erpreted as follows: 7 Copyright Electronic Industries Alliance Provided by IHS under license with EIANot for ResaleNo reproduction or networking permitted without license from IHS-,-,-STD-EIA TIA-455-B-ENGL 1778 323Yb00 Ob05582 O44 M TINE IA-455-B 7.1 When the unit of measure has traditionally or p
41、ractically always been exclusively metric or SI, parenthetical U.S. Customary units are not required (e.g., wavelengths, fiber diameters). 7.2 When Celsius temperatures are given, Fahrenheit equivalents be shown, but are not required, since Celsius-indicating equipment is commonly found in laborator
42、ies. If Fahrenheit equivalents are desired, however, observe the appropriate guidelines of 7.3 and 7.4. 7.3 In most cases, specified measurements (e.g., specimen lengths, weights, etc.) are selected for convenience only and exact equivalent conversions are not necessary. Unless the measurement in qu
43、estion requires precise equivalents, convert SI units to “convenient“ (.e., reasonable and practical) rounded U.S. Customary or inch-pound units (e.g., 25 mm is effectively equivalent to 1 inch for most purposes, and 1 meter is effectively equivalent to 3 feet). 7.4 In cases where essentially exact
44、equivalencies are required, conversions from Si to inch-pound units (or vice-versa) shall be carried out to an appropriate degree of accuracy. For rounding figures in such cases, refer to ASTM E 29. 7.5 Refer to ASTM E 380 for Winch-pound conversion and preferred units of measure. 8 Format for adden
45、da (FOTPs) In general, prepare FOTPs ( TIElA-455 Addenda) following the guidelines of TSM-6. If eventual conversion to an IEC standard is intended, reference to IECASO Directives, Part 3, is recommended; however, the guidelines of this document and of TSM-6 shall be followed in case of conflicts bet
46、ween these guidelines and the requirements of the IEC/ISO Directives. Reference may be made to the TSM-6 for standardized language and related information that may be helpful in the preparation of each FOTP. Effective with the date of this publication, all new and revised FOTPs shall be prepared usi
47、ng the foreword and eight standard section headings listed below. If a particular section is not appropriate for a particular FOTP, the section shall nevertheless appear, with some appropriate language (e.g. , Not Applicable, Not Required, etc.) entered following the section heading.
