MPTL Testing


MPTL to be specified within AS/NZS 11801-1

Channel testing is not appropriate as it does not test the plug on the end of the cable

High dependency links

Poor connector choice means high chance of failure

Poor termination means high chance of failure

Least tested links installed

Applications


Twisted Pair Applications

Giga Bits Class Category Channel Permanent Link

2.5 Class EA Cat 6A 100m 90m

5 Class EA Cat 6A 100m 90m

10 Class EA Cat 6A 100m 90m

25 Class I Cat 8.1 30m 26m

Mitigation and other techniques may allow for the application to run over a lower class

but there is NO guarantee


Remote Power over Twisted Pair

90-100 watts of delivery

• DC unbalance may affect the operation of a device

• DC unbalance testing may be called up as an additional field test

– Recommended infield tests to do for cabling supporting PoE

• Direct current (DC) resistance unbalance within a pair

• Direct current (DC) resistance unbalance between pairs

• Recommended infield tests

DO NOT SPECIFY COUPLING ATTENUATION


Remote powering

• 100 Watts

• ISO/IEC TS 29125 Technical specification information technology – Telecommunication cabling requirements for remote powering of terminal equipment

• 500mA per conductor (1 Amps per pair)

PoE

• 1000 Watt per pair

• 1000-2000 metres

• VoltServer

• Safe to touch (ES2)

Digital Electricity (Digital power)


RP1 ≤ 212 mA– Controls required

• Attachment of remote power equipment

• Planning of subsequent cabling installation

RP2 >212 mA and ≤500 mA– Controls required

• Average current restricted to a value between 212 mA and 500 mA

• Attachment of remote power equipment


• RP3 ≤500 mA– Controls required


Remote power category - Proposed

Channel lengths are likely to be reduced from 100 metres to address heat rise

Bundling is better than loose lay for addressing heat rise

Gaps in bundles reduce heat rise

One Pair cabling

• Generic cabling links in support of one pair cabling

• Long reach

– Not intended to replace four pair

– 1000 metre reach

– PAM 3 signalling

– Power delivery

• Industrial

– 15 metre reach

Indications from the IEEE802.3 liaison was that the IEEE 802.3bt draft had included a warning against using smaller than 26AWG cabling (90m).

– However, now the text indicates compliance with local, national and regional codes is required.

– Including NFPA70 in US (NEC)

• AS/CA S009 is likely to recommend 24 AWG as a minimum for twisted pair cabling


Remote powering over one pair

Work started on heat rise in one pair cabling in Paris February 2018

Australian expert requested heat rise in multicore cables be taken into account

Heat rise in multi-core cables would be useful to address the impact on safety in AS/CA S009

ISO/IEC TS 29125 provide some useful methods of calculation


Work started on addressing Issues related to the physical security of cabling and network infrastructure at the Washington meeting of SC25 WG3 in September 2018

The proposed standard objectives are to address

– Conformance requirements (Tiered)

– Risk assessment and security objectives

– Design

– Planning

– Monitoring system

Security of cabling (Physical Network Security)

Optical Fibre


• Cable type

• Connector type, polarity

• Pin in/pin out

• Key up-Key up Key down–Key down

• Number of cores

• Length (Propagation delay)

• Optical Attenuation of Channel Limit

Application dependent

on

• Multi-mode OM3, OM4 and OM5

• Multi-mode OM1 and OM2 to be grandfathered

• Single mode OS1a and OS2

• (OS1a replaced by OS1)

Cable selection


Optical Fibre Cabling

What Changed

New Standards

Dependency on technology and

supporting infrastructure

IoT Convergence

Power Delivery of Telecommunications

Cabling

Lack of understanding of

risk

Lack of expertise within emerging technology


Risk Mitigation Strategy

Risk Mitigation relates to a strategy to reduce exposure to risks or the likelihood of its occurrence based on four primary elements

• Risk Acceptance

• Risk Avoidance

• Risk Limitation

• Risk Transfer


Are you confident your strategy will address?

• The validity of your specification

• Information/Knowledge Dissimulation of your staff

• Test and acceptance criteria to mitigate risk

• Address Risks associated with engineered solutions

• Issues with remote powering

• The impact of product selection

• When standards don’t guarantee safety


Recommendations

• Engage with, attend training and seek advice from

– Industry organisations like BICSI

– Trusted advisors within your cable system vendors organisations

• Develop risk mitigation strategies

– Refresh your organisation specification and identify risk and communicate

– Develop staff knowledge

– Have preferred suppliers and contractors with suitable knowledge and understanding of the changes


What the future holds

Personal predictions for the next big things

1. Remote power - Now

2. One pair cabling – Next 1 to 3 years

3. Security of Physical infrastructure –Next 3 to 5 years
