44、ents may be useful to the reader: a) National Electrical Safety Code(NESC) (IEEE C2-2007) b) National Electrical Code(NEC) (NFPA 70 2005) Useful supplements to this Standard are BICSIs Telecommunications Distribution Methods Manual, the Customer-owned Outside Plant Design Manual, and the Information

45、 Transport Systems Installation Manual. These manuals provide practices and methods by which many of the requirements of this Standard are implemented.Other references are listed in annex B. AnnexesAnnex A is normative and is considered a requirement of this Standard. Annex B is informative and not

46、considered a requirement of this Standard. IntroductionPurposeThe purpose of this Standard is to specify cable and component transmission performance requirements for premises optical fiber cabling. It is intended to be used by manufacturers. Users, designers and installers may also find this Standa

47、rd useful. Additionally, this Standard is intended to be used as a reference by the suite of premises cabling standards listed in the Foreword. Specification of criteria Two categories of criteria are specified; mandatory and advisory. The mandatory requirements are designated by the word “shall“; a

48、dvisory requirements are designated by the words “should”, “may“, or “desirable“ which are used interchangeably in this Standard. Mandatory criteria generally apply to protection, performance, administration and compatibility; they specify minimally acceptable requirements. Advisory criteria are presented when their attainment may enhance the general performance of the cabling system in all its contemplated applications.
