19、end users and manufacturers of fiber-optic cable to specify a high bandwidth optical fiber optimized for enhanced performance at 850 nm. This Specification, in conjunction with Generic Specification TIA/EIA-4920000-B and Sectional Specification TIA/EIA-492A000-A, follow the specification structure o

20、f the National Electronic Components Quality Assessment System (NECQ). 1 Scope This Detail Specification applies to class Ia, graded-index, 50/125 m multimode optical fiber used as a component in the manufacture of fiber-optic cable. Applications include, but are not restricted to, the following: su

21、pport for short reach, high bit-rate systems in telephony, distribution and local networks, carrying data, voice and/or video services and on-premises intrabuilding and interbuilding fiber installations, including LANs, PBXs, video, various multiplexing uses, outside telephone cable plant use, and m

22、iscellaneous related uses. 2 Normative references Where applicable, this Detail Specification shall use information and related documents derived from, and referenced in: - TIA/EIA-4920000-B, Generic Specification for optical fibers; - TIA/EIA-492A000-A, Sectional Specification for class Ia graded-i

(Hereafter in this document, the above documents will be referred to as the Generic Specification, Sectional Specification, and Blank Detail Specification, respectively.) 3 Background information 3.1 Required specifications This Standard takes the entire contents of clause 4 of the Secti

25、onal Specification into account. The tables of this document include the minimum list of attributes specified in clause 4 of the Sectional Specification. 3.2 Marking Marking shall conform to the provisions of 3.3 of the Sectional Specification. 3.3 Numbering system The numbering system shall conform

26、 to 3.8 of the Generic Specification. Use the part number for all items on every purchase order to define particular choices for certain parameters that have multiple limit cells. See Annex B for definition and discussion of the part-number system. 3.4 Other requirements 3.4.1 Coating - Generic comp

27、osition: acrylic or other suitable polymeric material. - Removal method: mechanical or other suitable removal method. 3.4.2 Factory splicing Factory splicing is not permitted.

29、fety considerations shall conform to the principles given in 3.9.5 of the Generic Specification. 3.5 Ordering information Orders for fibers covered by this Specification shall contain, in clear or in coded form, the following minimum information: - Number and revision indicator of the Detail Specifi

30、cation. - Part number. See also 3.3 and Annex B of this Specification. 3.6 Additional information (not for inspection purposes) This Detail Specification supports Detail Specifications in the series of TIA Standards and ICEA Standards for fiber-optic cable. 3.7 Additional requirements There are no a

31、dditional requirements. Copyright Electronic Industries Alliance Provided by IHS under license with EIANot for ResaleNo reproduction or networking permitted without license from IHS-,-,-TIA/EIA-492AAAC-A 4 4 Inspection requirements 4.1 Qualification approval For qualification approval, the process s

32、hall be in accordance with 5.2 of the Sectional Specification, which in turn references 4.3 of the Generic Specification. The minimum sample size is the same as that specified for periodic requalification in the tables that follow. 4.2 Quality Conformance Inspection (QCI) Quality Conformance Inspect

33、ion shall be in accordance with 5.3 of the Sectional Specification. Note that periodic requalification is a standard component of the QCI program. 5 Quality assessment tables Tables 1 through 4 cover both qualification approval and QCI requirements, and represent the required list of attributes, as

34、given in 3.1 of this document. NOTE 1 - Column 1 cross references the subclause in the Sectional Specification that gives more detail on preferred values and characteristics. NOTE 2 - Column 3 often lists more than one test procedure for a given parameter. Many test procedures give interchangeable r

35、esults, based on interlaboratory comparisons. Whenever a non-TIA/EIA test or a TIA/EIA surrogate test is called out, there is a reference to Annex D, which gives further details. NOTE 3 - In column 4 certain performance requirements need more detailed discussion than a table can accommodate. For exa

36、mple, multiple values may be allowed, and specified alternatives are recommended. See Annex B. Copyright Electronic Industries Alliance Provided by IHS under license with EIANot for ResaleNo reproduction or networking permitted without license from IHS-,-,-TIA/EIA-492AAAC-A 5 Five annexes support th

37、e tables: - Annex A explains the QCI codes and levels. - Annex B covers performance requirements for certain attributes, the details of which cannot readily be accommodated in a table. This (normative) annex covers multicellular part numbers, as explained in 3.6.3 of the Generic Specification: attri

38、butes for which there are multiple limits or multiple nominal values. - Annex C describes the combined use of Differential Mode Delay and laser transmitter launch conditions in ensuring effective modal bandwidth-length product performance. - Annex D covers specialized tests such as: those not develo

39、ped by TIA/EIA (e. g., mechanical counter for length measurement); and those tests (part of EIA/TIA-455-A, usually) that are used as surrogates. Some detail is given. - Annex E shows a diagram of the material dispersion specification. Copyright Electronic Industries Alliance Provided by IHS under li
