3 Standards What are Standards? Standards represent the minimum required to maintain compliance. Principally about achieving minimum performance from products / standards driven by applications not end users. Standards are considered to be living documents. It is important that the region specific standards are quoted in the design and implementation.

4 Regional Standard Bodies Who are the national or regional standard bodies? USA INTERNATIONAL EUROPE ANSI/TIA ISO/IEC CENELEC The International Organization for Standardization (ISO) produces worldwide standards generated by country members. European Committee for Electrotechnical Standardization CENELEC produces European standards generated by EU country members. American National Standards Institute (ANSI) produces North American standards.

5 Who Else Is Out There? Standards and guidance is generated to support Design, Implementation, Methods and Products interoperability. There are many ways of doing the job: Trade Bodies and Standards publication. ETSI (European Telecommunications Standards Institute). ITU (International Telecommunications Union). IEEE (Institute of Electrical and Electronics Engineers, Inc). Manufacturers recommendations. Methods Manuals. Design Guidelines.

13 CENELEC EN Series There are 9 documents comprising EN 50173; the series includes: EN , Information Technology Generic Cabling Systems Part 1: General requirements. EN , Information Technology Generic Cabling Systems Part 2: Office premises. EN , Information Technology Generic Cabling Systems Part 3: Industrial premises. EN , Information Technology Generic Cabling Systems Part 4: Homes. EN , Information Technology Generic Cabling Systems Part 5: Data centres. EN , Information Technology Generic Cabling Systems Part 6: Distributed building systems. TR , Cabling guidelines in support of 10GBaseT. TR , Information Technology Implementation of BCT applications using cabling in accordance with EN TR , Information Technology Generic cabling systems Part 99-3: Home cabling infrastructures up to 50m in length to support simultaneous and non simultaneous provision of applications.

14 Highlights from EN Introduces the concept of environmental classification M.I.C.E. (Mechanical, Ingress, Climatic and Chemical, Electromagnetic). Environmental Class Mechanical rating M 1 M 2 M 3 Ingress rating I 1 I 2 I 3 Climatic and chemical rating C 1 C 2 C 3 Electromagnetic rating E 1 E 2 E 3 The requirements of a given classification cover the requirements of a lower classification, i.e. channels designed to operate under environmental conditions defined by M 2 shall continue to operate under environmental conditions by M 1. Specifies Channels for balanced and optical fibre cabling media. Specifies the minimum component requirements in support of these cabling elements. Provides a list of applications supported by generic cabling systems.

15 Highlights from EN (cont.) Classes for balanced cabling: Class A: specified up to 0.1MHz; Class B: specified up to 1MHz; Class C: specified up to 16MHz; Class D: specified up to 100MHz; Class E: specified up to 250MHz; Class E A : specified up to 500MHz; Class F: specified up to 600MHz; Class F A : specified up to 1000MHz; Class I: specified between 1600MHz and 2000MHz (TBD) ; Class II: specified between 1600MHz and 2000MHz (TBD). Channels of a given Class will support all applications of a lower Class.

16 Highlights from EN Supports two architectures: Type A: Generic cabling extends from the Service Distributor (SD) to the Service Outlet (SO). Channel = 100m Link EQP EQP Cord SD Horizontal Cable The generic cabling shall be able to support the broadest set of existing and emerging application within the environmental conditions: Considerations for Cat.6A (Class E A ) and Cat.7A (Class F A ). Consideration for PoE applications and remote powered devices. SCP SCP Cable SO SA Cord TE

17 Highlights from EN (cont.) Type B: Generic cabling extends from an SD to the Service Concentration Point (SCP) provide the opportunity for: Application specific cabling to be installed between the SCP and terminal equipment. Application specific cabling to be connected at the SCP. SCP Cable SO SA Cord TE TE connection configured as Plug Socket EQP EQP Cord SD Horizontal Cable SCP SCP Cable SCP Cable SA Cord TE TE TE connections directly attached to cabling

18 Highlights from EN (cont.) SCP advantages: An SCP allows coverage area connections to be easily reconfigured. Consolidation Points (CP) for voice and data and SCPs for BAS applications can coexist within the same zone box. We need to think only for the number of IP applications/services needed.

19 CENELEC Installation Standards There are 4 documents comprising EN 50174; the series includes: EN , Information Technology Cabling installation Part 1: Installation specification and quality assurance. EN , Information Technology Cabling installation Part 2: Installation planning and practices inside buildings. EN , Information Technology Cabling installation Part 3: Installation planning and practices outside buildings. TR , Information Technology Cabling installation Remote Powering (TBD).

ISO/IEC TR , Technical Report for the next generation Twisted-pair cabling, for supporting 40Gb/s applications (in support of the IEEE 802.3bq project for 40GBASE-T, next generation 40G Ethernet over-twisted-pair). ISO/IEC , 2 nd Edition This document is similar to EN and EN ISO/IEC , 2 nd Edition Test method improvements to support component and channel performance for OM4 optical fiber media classes.

26 ISO/IEC Standards Automated Infrastructure Management (AIM) systems Automated cabling administration systems: intelligent patchpanels, management program interface. Two open projects: ISO/IEC Amd. 1, adds informative text covering AIM functional guidelines. ISO/IEC 18598, requirements of AIM elements supporting cabling systems within buildings. ISO/IEC Telecommunications Bonding Requirements of bonding-to-earth systems supporting cabling within buildings.

27 Highlights from ISO/IEC Copper Cabling Items Defines the component, Link and Channel performance for balanced twisted pair copper. Class C up to 16MHz; Class D up to 100MHz; Class E up to 250MHz; Class E A up to 500MHz; Class F up to 600MHz; Class F A up to 1000MHz; Class I between 1600MHz and 2000MHz; Class II between 1600MHz and 2000MHz.

28 Highlights from ISO/IEC (cont.) Copper Cabling Items New IEC definitions of cable construction/design with corresponding IEC definitions for performance.

29 Highlights from ISO/IEC (cont.)

30 Highlights from ISO/IEC (cont.) Copper Testing Issues If the coupling attenuation of Class E A or F A permanent links or CP links is at least 10dB better than the corresponding channel coupling attenuation requirements, and Class F A permanent links or CP Links are at least 25dB better than the corresponding channel coupling attenuation requirements, then the ANEXT requirements are met by design. Effectively this means that testing and validation for ANEXT is not required on site.

31 Highlights from ISO/IEC (cont.) Optical Fibre Cabling Items Optical fibre adapters and connectors should be protected from dust and other contaminants, specifically while they are in an unmated state. End faces of connectors shall be inspected according to ISO/IEC and subsequently cleaned when necessary, prior to connection. Maximum mated connector insertion loss: 100% 0.75dB; 95% 0.50dB; 50% 0.35dB. The TO shall present a duplex LC connector that complies with IEC
