3 Drivers for change IoT Powering over telecommunications cabling 5 October

4 Power over telecommunications cabling Industry trends 25 Watts per pair over 4 pair 800 Watts to 1000 Watts per pair over telecommunications cabling Issue related to heat rise Bundling Installation conditions Circuit activated Conductor Size Ambient temperature 5 October

5 Requirements Power Internet of Thing Communications New and emerging Standard to address IoT Distributed building services (AS ) Modular Plug Terminated Links MPTL (AS/NZS ) One pair cabling delivering power and communications New Energy Classifications (ES1, 2 & 3) New remote power classification (RP1,2 & 3) New cable bundling requirements (1 & 4 Pr) 5 October

6 How are standards in Australia addressing the issues Performance Safety AS Standards AS/NZS Standards ISO/IEC Standards SA Technical Specifications SA Technical Reports AS/CA Standards Minimum requirement- Safety may not be assured Engineered solutions 5 October

7 What's changing with Standards for customer cabling NEW MANDATORY STANDARDS PROPOSED AS/CA S009 and AS/CA S008 Changing of voltage classification to new requirements based on new Energy source classifications ES1, ES2 & ES3 ES3 is hazardous No Maximum Voltage No Maximum Current LV Telecommunication falls under ES3 Addressing remote powering Minimum conductor sizes Mandatory earthing 5 October

9 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 5 October

10 What's changing with Standards for customer cabling PERFORMANCE STANDARDS Based on ISO/IEC series Modular plugs terminated links in Australia and New Zealand One pair cabling to 1000m Coming soon Retiring of AS/NZS 3080 New Bonding (earthing) requirements New Distributed Building Services Standards (IoT) 5 October

11 New Customer Cabling Standard (AS/NZS 3080) Performance Standard AS/NZS Standard Descriptor Minimum Class General requirements Cable Distributors to Outlet Coverage AS Office premises Class E Cat 6 CD-BD-FD-CP-TO 2,000m AS Industrial premises Class D Cat 5 CD-BD-FD-ID-CP-TO 10,000m AS Homes Class D Cat 5 PHD-SHD-BO/TO 100m AS Data centres Class E A Cat 6 A (ENI)-MD-ID-ZD-LDP- EO AS Distributed building services 2,000m Class E A Cat 6 A CD-BD-SD-SCP-SO 10,000m 5 October

12 New Support standards ISO/IEC Information technology -- Implementation and operation of customer premises cabling -- Part 2: Planning and installation AS/NZS 3084 Telecommunications installations - Telecommunications pathways and spaces for commercial buildings ISO/IEC Information technology -- Telecommunications bonding networks for buildings and other structures AS/NZS Information technology -- Implementation and operation of customer premises cabling -- Part 3: Testing of optical fibre cabling IEC (AS/NZS version to withdrawn) Specification for the testing of balanced and coaxial information technology cabling - Part 1: Installed balanced cabling as specified in ISO/IEC and related standards Addresses Installation and quailty plans Pathways and spaces Earthing requirements for telecommunication systems In-field Optical fibre testing In-field Twisted Pair testing Performance Performance Performance Performance Performance 5 October

14 Disconnect under load-100 watts Load Carried over 8 conductors Load Carried over 2 conductors 5 October

15 Modular Plug Terminated Link - MPTL SCP Patch Panel Plug 5 October

16 MPTL to be specified within AS/NZS MPTL Testing 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 5 October

17 Applications 5 October

18 Twisted Pair Applications Giga Bits Class Category Channel Permanent Link 1 Class D Cat 5 100m 90m 2.5 Class E A Cat 6 A 100m 90m 5 Class E A Cat 6 A 100m 90m 10 Class E A Cat 6 A 100m 90m 25 Class I Cat m 26m 40 Class I Cat m 26m Mitigation and other techniques may allow for the application to run over a lower class but there is NO guarantee 5 October

19 Remote Power over Twisted Pair 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 5 October

20 Remote powering PoE 100 Watts ISO/IEC TS Technical specification information technology Telecommunication cabling requirements for remote powering of terminal equipment 500mA per conductor (1 Amps per pair) Digital Electricity (Digital power) 1000 Watt per pair metres VoltServer Safe to touch (ES2) 5 October

21 Remote power category - Proposed 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 Planning of subsequent cabling installation RP3 500 ma Controls required Planning of subsequent cabling installation Bundling is better than loose lay for addressing heat rise Gaps in bundles reduce heat rise Channel lengths are likely to be reduced from 100 metres to address heat rise

22 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 5 October

23 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 provide some useful methods of calculation 5 October

24 Security of cabling (Physical Network Security) 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

25 Optical Fibre 5 October

26 Optical Fibre Cabling Application dependent on 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 Cable selection Multi-mode OM3, OM4 and OM5 Multi-mode OM1 and OM2 to be grandfathered Single mode OS1a and OS2 (OS1a replaced by OS1) 5 October

27 New Standards Dependency on technology and supporting infrastructure IoT Convergence Power Delivery of Telecommunications Cabling Lack of understanding of risk What Changed Lack of expertise within emerging technology 5 October

28 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 5 October

29 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 5 October

30 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 5 October

31 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
