29、s of fiber-optic cable to specify thechoice of single-mode optical fiber contained in the cable. This Specification, in conjunction withGeneric Specification TIA/EIA-4920000-B and Sectional Specification TIA/EIA-492C000, followthe specification structure of the National Electronic Components Quality

30、 Assessment System(NECQ)._1 Scope_This Detail Specification applies to a Class IVa dispersion-unshifted single-mode optical fiberthat has low attenuation at wavelengths near the water peak (typically near 1383 nm). Class IVasingle-mode fiber has a nominal zero-dispersion wavelength in the 1310 nm tr

31、ansmissionwindow. The fiber is commonly referred to as a dispersion-unshifted (or non-shifted) fiber, andits dispersion characteristic is approximated by a differentiated Sellmeier equation (see 4.4.4 ofthe Sectional Specification). This Detail Specification applies to a sub-category of a Class IVaf

32、iber that is termed “Low Water Peak” fiber. These fibers are characterized by having a low,environmentally stable attenuation coefficient in the vicinity of 1383 nmtraditionally referred toas the “water peak.”_2 Normative references_Where applicable, this Detail Specification shall use information a

43、nd characteristics.NOTE 2 - Column 3 often lists more than one test procedure for a given parameter.Many test procedures give interchangeable results, based on interlaboratorycomparisons. Whenever a non-TIA/EIA test or a TIA/EIA surrogate test is called out,there is a reference to Annex C or D, whic

44、h gives further details.NOTE 3 - In column 4, certain performance requirements need more detailed discussionthan a table can accommodate. For example, multiple values may be allowed, andspecified alternatives are recommended. See Annex B.Four annexes support the tables:- Annex A (normative) explains

45、 the QCI codes and levels.- Annex B (normative) covers performance requirements for certain attributes, the details ofwhich cannot readily be accommodated in a table. This annex covers multicellular partnumbers, as explained in 3.6.3 of the Generic Specification: attributes for which there aremultip
