5、mercial building telecommunications cabling standard Part 1: General requirements Addendum 3 Supportable distances and channel attenuation for optical fiber applications by fiber type. This Standard is an adoption of the identically titled ANSI/TIA (American National Standards Institute/Telecommunic
6、ations Industry Association) Standard 568-B.1-3-2003 and is the product of the Telecommunications Industry Association TR-42 Technical Committee, which included a number of Canadian members in order to ensure that Canadian perspectives and requirements were addressed. It is written in SI (metric) un
7、its with yard/pound (imperial) units in parentheses. This Standard has been adopted with no technical deviations. Where code requirements or regulations necessitate changes from US to Canadian references, they should be made by the user, as follows: (a) Throughout this Standard, replace the term “Am
8、erican” with “Canadian”, as applicable. (b) Throughout this Standard, replace the term “state” with “provincial or territorial”, as applicable. (c) Throughout this Standard, replace “NEC” with “CE Code, Part I” (Canadian Electrical Code), as applicable. In addition, (i) where reference is made to “c
9、onduit”, replace it with “conduit/EMT” (electrical metallic tubing) because, in accordance with the Canadian Electrical Code, Part I, EMT is not considered a type of conduit; and (ii) the definitions of the following terms are to be taken from the Canadian Electrical Code, Part I: “Bonding”, “Ground
10、”, and “Raceway”. (d) Throughout this Standard, where reference is made to “FCC”, replace it with “CRTC” (Canadian Radio-television and Telecommunications Commission), or “Industry Canada”, as applicable. (e) The following Standards, published by the Canadian Standards Association, are adoptions of
11、TIA/EIA Standards. The requirements of these CSA Standards take precedence over the TIA/EIA Standards on which they are based; any reference in CSA T568.1-3 to the TIA/EIA Standard is to be replaced by a reference to the equivalent Canadian Standard: (i) T568.1-05, Commercial building telecommunicat
12、ions cabling standard Part 1: General requirements; and (ii) T568.3-05, Optical fiber cabling components standard. (f) Throughout this Standard, replace the term “Listed” with “Approved as applied to electrical equipment”.Commercial building telecommunications cabling standard Part 1: General requir

44、es of fibers are included in these footnotes where applicable. 3850-nm laser-optimized 50/125 m multimode fiber supports the same maximum channel distances and insertion losses as 500/500 MHzkm 50/125 m multimode fiber for applications specified within TIA-568-B.1. 4For 62.5/125 m fiber, IEEE specif
45、ies 26 m (85 ft) for fiber with 160/500 MHzkm modal bandwidth and 33 m (108 ft) for fiber with 200/500 MHzkm modal bandwidth. 5For 50/125 m fiber, IEEE specifies 66 m (216 ft) for fiber with 400/400 MHzkm modal bandwidth and 82 m (269 ft) for fiber with 500/500 MHzkm modal bandwidth. 6Includes maxim
46、um channel insertion loss plus additional allowable insertion loss. 7For 62.5/125 m multimode fiber, IEEE specifies 2.6 dB for fiber with 160/500 MHzkm modal bandwidth and 2.5 dB for fiber with 200/500 MHzkm modal bandwidth. 8For 50/125 m multimode fiber, IEEE specifies 2.2 dB for fiber with 400/400
47、 MHzkm modal bandwidth and 2.3 dB for fiber with 500/500 MHzkm modal bandwidth. 9Channels are specified within TIA-568-B.1 up to 3 km (9840 ft). Distances provided within this table are the maximum distances specified within IEEE 802.3 and invoke cabling specifications that may differ from TIA-568-B
48、.3. 1010GBASE-E channels are specified to have a minimum of 5 dB and maximum of 11 dB channel insertion loss. 11For 50/125 m multimode fiber, IEEE specifies 240 m (787 ft) for fiber with 400/400 MHzkm modal bandwidth and 300 m (984 ft) for fiber with 500/500 MHzkm modal bandwidth. 12The maximum chan
