28、Optimized Bandwidth Characteristics Specified for Wavelength Division Multiplexing Introduction This Standard enables end users and manufacturers of fiber-optic cable to specify a high bandwidth optical fiber optimized for enhanced performance for wavelengths in the vicinity of 850 nm to 950 nm in s
29、upport of single wavelength or multi-wavelength transmission systems. This optical fiber meets all the relevant requirements of the fiber specified by TIA-492AAAD 21 and therefore is considered compliant and compatible. This Specification, in conjunction with Generic Specification TIA-4920000-B and
30、Sectional Specification TIA-492A000-A, follow the specification structure of the National Electronic Components Quality Assessment System (NECQ). 1 Scope This Standard applies to class Ia, graded-index, 50/125 m multimode optical fiber used as a component in the manufacture of fiber-optic cable. App
31、lications include, but are not restricted to, the following: support 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, SANs, Data Center
32、s, PBXs, video, various multiplexing uses, outside telephone cable plant use, and miscellaneous related uses. 2 Normative references The following standards contain provisions that, through reference in this text, constitute provisions of this Standard.
