综合布线系统标准
综合布线系统自问世以来已经历了近二十年的历史,这期间,随着信息技术的发展,布线技术也在不
断推陈出新;与之相适应,布线系统相关标准的发展也有相当长的时间,国际标准化委员会 ISO/IEC ,欧
洲标准化委员会 CENELEC 和北美的工业技术标准化委员会 TIA/EIA 都在努力制定更新的标准以满足技术
和市场的需求。 为使大家更好的了解和应用这些标准, 我们在此将综合布线系统相关标准向大家作一介绍。
以下为与布线有关的组织与机构:
ANSI 美国国家标准协会 American National Standards Institute
BICSI 国际建筑业咨询服务 Building Industry Consulting Service International
CCITT 国际电报和电话协商委员会 Consultative Committee on International Telegraphy and
Telephony (现在 , ITU-TSS)
EIA 电子行业协会 Electronic Industries Association
ICEA 绝缘电缆工程师协会 Insulated Cable Engineers Association
IEC 国际电工委员会 International Electrotechnical Commission
IEEE 美国电气与电子工程师协会 Institute of Electrical and Electronics Engineers
ISO 国 际 标 准 化 组 织 International Standards Organization (formally, International
Organization for Standardization)
ITU-TSS 国 际 电 信 联 盟 - 电 信 标 准 化 分 部 International Telecommunications Union -
Telecommunications Standardization Section
NEMA 国家电气制造商协会 National Electrical Manufacturers Association
NFPA 国家防火协会 National Fire Protection Association
TIA 电信行业协会 Telecommunications Industry Association
UL 安全实验室 Underwriters Laboratories
ETL 电子测试实验室 Electronic Testing Laboratories
FCC 美国联邦电信委员会 Federal Communications Commission (U.S.)
NEC 国家电气规范 National Electrical Code (issued by the NFPA in the U.S.)
CSA 加拿大标准协会 Canadian Standards Association
ISC 加拿大工业技术协会 Industry and Science Canada
SCC 加拿大标准委员会 Standards Council of Canada
这些组织都在不断努力制定更新的标准以满足技术和市场的需求。
目前我国布线行业主要参照国际标准、美洲标准、国家标准、及国内行业标准实施。
一、美洲标准
¨ TIA/EIA 标准
– ‘568(1991)商业建筑通信布线标准
? TSB-36‘568 增补— 电缆规格
? TSB-40A ‘ 568 增补— 连接硬件
– ‘569(1990)商业建筑。电信标准。通道和空间
– ‘570(1991)居住和轻型商业建筑
– ‘606(1993)商业建筑内电信基础设施的管理
– ‘607(1994)商业建筑中电信系统接地
商业布线系统的标准制定计划可以追溯到 80 年代中期, 在此之前主要是由关键厂商对布线系统的分类起主
