13. The NEW 568-C.0 Standard
Herb Congdon

14. 568-C – Why? ANSI mandates a 5-year life for published standards
Revised, reaffirmed or withdrawn
TIA-568B published May 2001
>5 years ago
Many addenda since publication
6 addenda to 568-B.1
10 addenda to 568-B.2
1 addendum to 568-B.3

15. Improvement Opportunity
Complaint: Duplicated information
Cause: Synchronizing and updating multiple documents is complicated
Solution: Centralize common information

16. Improvement Opportunity
Complaint: Lengthy development of new Standards
Cause: Creating new premise Standards is unnecessarily repetitive
Solution: Establish common information in one document

17. Improvement Opportunity
Complaint: Gaps in Standards Coverage
Cause: Standards tend to be too specific
Solution: Start with common information applicable everywhere, then manage exceptions and allowances specific to the premise

18. Coffee
Hot
Chocolate
The Plan

19. Solution: A Generic Cabling Standard
A new standard for generic cabling C.0, Generic Telecommunications Cabling for Customer Premises
The foundation for future Standards
The cabling Standard when documents specific to a premises are not available
Consolidates common information in one document
Content from 568-B.1 & addenda split between C.0 and C.1

20. Splitting 568-B.1 568-B.1 (94 pgs) 568-C.0 Generic (~60 pgs) 568-C.1
CBC
(~35 pgs)

21. 568-C Series Documents One New Standard (568-C.0) Three Revisions
568-C.0 – generic structured cabling
Three Revisions
568-C.1 – commercial building cabling
Office-oriented buildings
568-C.2 – copper cabling components
568-C.3 – fiber cabling components

22. Three Document Types Common Standards Premise Standards
Generic
Pathways & Spaces
Administration, etc.
Premise Standards
Commercial Building
Residential
Data Centers, etc.
Component Standards
Copper
Optical Fiber

23. Looking Forward Over the next 3-5 years
Other premises Standards will be revised to acknowledge 568-C.0
List appropriate exceptions and allowances
Existing common Standards modified to broaden scope
Replace “commercial building” focus and terminology
Become more generic in nature
New Standards will be built on the foundation of 568-C.0

Requirements for category 5e, 6, and 6A screened cable only
IEC reference measurement
coupling attenuation: Coupling attenuation is the ratio, in dB, of the transmitted power in the signal conductors and the maximum radiated peak power, conducted and generated by the excited common mode currents.
Measurement application to both screened and unscreened products. Not a field test measurement.
Coupling attenuation is under study.
Coupling attenuation shall be measured in accordance with IEC or IEC for all screened pairs of horizontal cable from 30 MHz up to the maximum specified frequency for the specified category.
NOTE - Measurements are made from 30 MHz to 1000 MHz for all devices under test, but the measurements above the upper frequency of the specified category are for information only.
