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.

Regional Standard Bodies

Who are the national or regional standard bodies?

• 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.

INTERNATIONAL EUROPE

USA

ISO/IEC CENELEC ANSI/TIA

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.

Cables and connections of different Categories may be mixed within a channel, however the resultant cabling performance will be determined by the Category of the lowest performing component.

• EN 50173-6, Information Technology – Generic Cabling Systems – Part 6: Distributed building

systems.

• TR 50173-99-1, Cabling guidelines in support of 10GBaseT.

• TR 50173-99-2, Information Technology – Implementation of BCT applications using cabling in

accordance with EN 50173-4.

• TR 50173-99-3, 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.

Highlights from EN 50173-1

Introduces the concept of environmental classification M.I.C.E. (Mechanical, Ingress, Climatic and Chemical, Electromagnetic).

Environmental Class

1 2 3

Mechanical rating M₁ M₂ M₃

Ingress rating I₁ I₂ I₃

Climatic and chemical rating C₁ C₂ C₃

Electromagnetic rating E₁ E₂ E₃

• The requirements of a given classification cover the requirements of a lower classification, i.e. channels designed to operate under environmental conditions defined by M₂ shall continue to operate under environmental conditions by M₁.

• 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.

Highlights from EN 50173-1 (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).

Highlights from EN 50173-6

Supports two architectures:

Type A: Generic cabling extends from the Service Distributor (SD) to the

Service Outlet (SO).

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.

Highlights from EN 50173-6 (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.

Highlights from EN 50173-6 (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.

CENELEC Installation Standards

There are 4 documents comprising EN 50174; the series

includes:

• EN 50174-1, Information Technology – Cabling installation –

Part 1: Installation specification and quality assurance.

• EN 50174-2, Information Technology – Cabling installation –

Part 2: Installation planning and practices inside buildings.

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.

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 14763-3 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 61754-20.
