TelecommunicationCabling Standards

to address IoT and power delivery

8 April 2019 www.vti.net.au 3

Drivers for change

• IoT

• Powering over telecommunication cabling


Internet of things

• The Internet of things refers to the concept of extending Internet connectivity beyond conventional computing platforms such as personal computers and mobile devices, and into any range of traditionally "dumb" or non-internet-enabled physical devices and everyday objects.

Remote powering over telecommunication cabling

Industry trends

100 watts over 4 pair – PoE

• 100 metre range

• 23-24 AWG

1000 watts on one pair over telecommunication cabling

• 2,000 metre range

• Larger conductor cabling

• Safe to touch


Internet of Things

Requirements

• Power

• Communications

Trends

• Now• Distributed building services standards

• Coming• One pair cabling delivering power and

communications project approved by IEEE 802.3 committee

• One pair connector chosen by ISO/IEC 11801.1 committee (LC)

• 1000 metre range


Digital power

Transmitter

Data

1.1ms 0.4ms

Energy Packet

Energy

Up to 2Km & 1000Watts

1) Send energy packet (~600 per second)2) STOP3) Measure energy decay4) Safe? send another packet; else STOP5) Receiver converts back to Analog Electricity (AE)

Electricity that is safe to touch & smart!

IEC 62368-1 Approved Limited Power Source!

Also an IEC 60950-1 &-21 Approved LPS

The Solution

Source – Prysmian Group

How are cabling standards in Australia addressing the issue

Safety -Mandatory

• Revision of AS/CA S008 and AS/CA S009 Standards

• New energy source specified- Including hazardous services (ES3)

• Engineered solution allowed

Performance – Commercially invoked

• New Structure for Standards

• Some joint AS/NZS Standards

• Some Australia only Standards


What's changing with Standards for customer cabling

• MANDATORY STANDARDS

• AS/CA S009 and AS/CA S008- out for public comment

• Changing of voltage clarification to new requirements based on new Energy source classification

• ES1, ES2 and ES3

• ES3 is hazardous

• No maximum Voltage

• No Maximum Current

• LV Telecommunication falls under ES3

• 400v and 750 mA restriction placed on generic cabling

• Minimum conductor sizes to address the delivery of power over communication cabling (0.5mm)

• Tightening and renaming of the Fitness for Purpose clauses

• ES3 generic cabling requirement added

• 6mm earth required at distributors terminating external cabling


Mandatory Standards - Safety

AS/CA S008 Requirements for customer cabling products

Cable Product requirements

MANDATORY

AS/CA S009 Installation requirements for Customer Cabling

Telecommunication cabling requirements

MANDATORY


What's changing with Standards for customer cabling

PERFORMANCE STANDARDS

• Based on ISO/IEC 11801 series

• Modular plugs terminated links added to AS/NZS 11801.1

• Retiring of AS/NZS3080

• New earthing requirements

• New Distributed Services Standard AS 11801.6

• New minimum class specified

• Category 8.1 and Category 8.2 Introduced

New Support standards

ISO/IEC 14763.2 Information technology -- Implementation and operation of customer premises cabling -- Part 2: Planning and installation

Addresses Installation and quailty plans

Performance

AS/NZS 3084 Telecommunication installations -Telecommunication pathways and spaces for commercial buildings

Pathways and spaces Performance

ISO/IEC 30129 Information technology -- Telecommunication bonding networks for buildings and other structures

Earthing requirements for telecommunication systems

Performance

AS/NZS 14763.3 Information technology -- Implementation and operation of customer premises cabling -- Part 3: Testing of optical fibre cabling

In-field Optical fibre testing Performance

IEC 61935-1(AS/NZS version tobe withdrawn)

Specification for the testing of balanced and coaxial information technology cabling - Part 1: Installed balanced cabling as specified in ISO/IEC 11801 and related standards

In-field Twisted Pair testing Performance


Remote Power over Twisted Pair

90-100 watts of delivery

• DC unbalance may effect 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


Disconnect under load - 100 watts

Load Carried over 8 conductors

Load Carried over 2 conductors


Modular Plug Terminated Link - MPTL

Patch Panel Plug

SCP


MPTL Testing


MTPL 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 for safety and security systems along with operational service availability

Poor connector choice means high chance of failure

Poor termination means high chance of failure

Least tested links installed

Applications requirements


Twisted Pair Applications

Giga Bits Class Category Channel Permanent Link

1 Class D Cat 5 100m 90m

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

40 Class I Cat 8.1 30m 26m

Migration and other techniques may allow for the application to run over a lower class but there is no guarantee

What Changed

New Standards

Dependency on technology and

supporting infrastructure

IoT Integration

Power Delivery of Telecommunication

Cabling

Lack of understanding of

risk

Lack of expertise within emerging technology


Risk Mitigation Strategy

8 April 2019

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

www.vti.net.au 25

Duty of care

Duty of care requirements

•Exercise due care, skill and diligence

•The level of due care, skill and diligence, is that usual amongst peers

•Not to engage in conduct that is misleading or deceptive, or likely to mislead or deceive

•This includes silence or a failure to disclose certain information

•Ensure that your advice (Design or installation) is reasonably fit for the purpose it is being sort

Liability arising from failure to meet duty of care could

include

•Compensation for negligence

•Compensation for the reduction of value of the cabling system

•Damages for any loss or damage suffered

•Criminal charges - Appear before the Coroner

Failure to meet duty of care may mean that you are not

entitled to make a claim under your insurance

•Under the insurance law, by knowingly omitting information, you are breaching your duty of good faith and duty to make full and proper disclosures to your insurer

Section 13 Insurance Contract Act 1984 (Cth)

Section 21 Insurance Contract Act 1984 (Cth)

Understanding the changes in risk profile

• Higher dependency on technology carries higher dependence for physical layer

• Service availability affects safety, security and operational networks

• The protection offered by standards are eroded if they are not invoked correctly

• New standards address newly identified technologies and problems

www.vti.net.au 8 April 2019 27

Risk Minimisation Strategies

• Update specification to reflect latest standard

• Read conformance clause 4 of AS/NZS and ISO/IEC standards to confirm conformance requirement of the standards

• Consider specifying specific clauses of a standard in place of the whole standard

• TCA1 forms provide a safety sign-off by a registered subject matter expert

• Use reliable brand with warranty program

www.vti.net.au 8 April 2019 28

• Obtain statement of compliance by vendors to confirm “met by design” requirements

• Alien crosstalk

• Disconnect under load

• Minimum cable length for a CP/SCP

• Cabling requirements to address 100 Watt PoE deployment (RP3)

• Product is approved

• Match installation conformance testing to the risk profile

• Get independent sign off by subject matter expert

Are you confident your organisations strategy will address

• The validity of your specification

• Information/Knowledge Dis-simulation 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
