The focus of the day’s activities dealt with ISO/IEC 11801 Information Technology — Generic Cabling for Customer Premises — Part 1: General requirements and the expectation that this work will end in another Committee Draft of the standard.
JTC1 SC25 WG3 Day 1
Day one of WG 3 finished with as many questions as were answered. The meeting was informed that IEEE 802.3CG had been published which deals with one pair Ethernet delivering 10 MBits/s. Clearly an application designed for the delivery of IoT Services.
The scope of JTC1 SC25 change to include IoT was confirmed within the meeting.
International Standards meeting comes to Sydney
The International Standards JTC1 SC25 WG3 Customer Premises Cabling is being hosted by Standards Australia and sponsored by VTI Services this week.
AS/NZS IEC 61935.1:2006 Testing of balanced communication cabling in accordance with ISO/IEC 11801 Installed cabling has been withdrawn and is unlikely to be replaced in the foreseeable future.
Friday 24th May 2019 saw the superseding of a number of long-standing standards associated with generic cabling for customer cabling based on the ISO/IEC 11801.x series.
Australia and New Zealand picked up part one of the series, however New Zealand opted not to pick up the other parts as such the other parts of the series were picked up as Australian only standards.
New Zealand now references the ISO/IEC international standard directly for the other parts of the series.
The draft standards for AS/CA S008 and AS/ CA S009 covering mandatory standards for customer (telecommunication) cabling is out for public comment.
One of the major changes for these revisions are the change to energy sources from voltage classifications. This was brought about by the publication of AS/NZS 62368.1:2018 Audio/video, information and communication technology equipment Part1: Safety requirements.
VTI Services will be closed for the holiday season from Monday 24th December and return on Monday 14th January 2019.
ICT Standards training/workshop in Auckland 29th November 2018
VTI Service is to delivery a consulting engineering workshop in Auckland on 29th November in conjunction with BISCI. The workshop is based around changes to performance standards and the proposed introduction of new energy sources (ES1, ES2 and ES3) and remote powering classifications (RP1, RP2 and RP3).
The workshop also will address
The draft AS/NZS 11801.1 Information technology Generic cabling for customer premises, Part 1: General requirements (ISO/IEC 11801-1:2017, MOD) sees the introduction of two new categories of optical fibre cable and the grandfathering for three of the existing categories.
Many thanks to Schneider for allowing me to present at their consultancy breakfast in Perth this week.
It was great to see the industry in Western Australia actively start to look at how to address the issues around remote powering.
The assessment requirement to determine maximum length of permanent links and channel affected by heat rise in the cable bundles seem to draw the most interest and gave me a chance to run VTI Services modelling tool which is still under development.
New Energy Sources (ES) have been introduced into the Australian and New Zealand market place which is set to be picked up by AS/CA S009 Installation requirements for customer cabling (Wiring Rules) due out in the next few weeks for public comment.
The long awaited replacement/s for AS/NZS 3080 is currently out for public comment.
AS/NZS 3080 will be replaced by a series of standards addressing specific premise types which includes office, industrial, single tenant home, Data Centres and Distributed Building services.
Just in time for Christmas, the international standard six-part series ISO/IEC 11801.x has been published.
The original ISO/IEC11801 document is the base document for AS/NZS 3080.
A project proposal to adopt these standards has been approved by Standards Australia and the project will be kicked off 21st February 2018.
The half day course addressed mandatory labelling requirements of AS/CA S009 and AS/NZS IEC 60825.1 associated with communication systems and was aimed at educating implementation and operational staff as to the obligations under the standards.
The course addressed hazard control strategies and risk mitigation techniques which included engineering controls and administrative controls associated with laser communication within customer premises.
VTI Services will be closed for the holiday season from Friday 22/12/17 and return on Monday 8/01/18.
JTC1 SC25 WG3 addresses the international standard on which AS/NZS3080 performance standards for customer cabling (Telecommunications) and associated standards are based.
The current Australian and New Zealand standard AS/NZS 3080 for generic customer cabling is based on the international standard ISO/IEC 11801 which is currently under revision. With ISO/IEC 11801 undergoing a major revision the Australian and New Zealand Standard AS/NZS3080 needs to be updated in line with ISO/IEC 11801 to remain relevant. The ISO/IEC 11801-x series is currently at Final Draft stage and is expected to be finalised on 15th September 2017.
Work continues on the amendment of AS/NZS 3080 (ISO/IEC 11801) along with revision of AS/CA S008 and AS/CA S009 (Mandatory Standards).
The Communication Alliance working committee (WC80) started the revision of AS/CA S008 and AS/CA S009 on Tuesday 13th June 2017.
“AS/CA S008 Requirements for customer cabling products” and “AS/CA S009 Installation requirements for customer cabling (Wiring rules)” are mandatory standards called up by the Telecommunication Act and the Cabling Provider Rules and are regulated by the Australian Communications and Media Authority (ACMA).
Mandatory Standards within the Australian Marketplace had traditionally provided a level of comfort that the cabling products utilised within Australia were safe.
In recent times however, due to disruption in the traditional supply chain brought about in part by direct purchasing from overseas over the internet and by new players entering the marketplace that are not familiar with local regulations or choosing to ignore them has seen non approved products being supplied and installed within Australia.
Coupling Attenuation is to be an optional in-field test for installation conformance testing
While it is possible, it will not be a perfect fit.
The adopted changes to the Building Code of Australia appear not to address adequate pathways and space requirements for future deployment of Internet of Things technologies nor have a common carrier lead-in requirement.
AS/NZS 14763.3 was published on Friday 3rd February 2017.
With the publication of AS/NZ 14763.3:2017 fibre testing, the requirements now align with current international standards.
Key elements of change from the previous version include
The adoption of the draft ISO/IEC 11801-1 OS1 (AS/NZS3080) will see the likely inclusion of 1383nm optical attenuation requirements for OS1 “cabled optical fibre” (optical fibre cores within a cable).
The inclusion of 1383 nm requirements for cabled optical fibre was originally specified for OS2, which was introduced as a low water peak cable with specified optical attenuation requirements at 1383nm and additionally had better optical attenuation characteristics at 1310nm and at 1550nm than that of OS1.
VTI Services will be closed for the holiday season from Friday 23/12/16 and return on Monday 16/01/17.
Any test verification or pricing work will need to be submitted by COB 16th December 2016 if required before the Christmas break.
While OM1 will still be deployed in the marketplace to match legacy systems, the utilisation on green-field sites looks to be at an end for OM1 with the minimum fibre set to be specified as OM3 (50 µm).
OM1 and OM2 were originally specified as either 62.5 or 50 µm, with the market typically specifying OM1 as 62.5 µm, while OM2 gained little market share and with the advent of laser optimised OM3 at 50 µm, OM2 saw very low levels of adoption.
ISO/IEC 11801-6 is currently at DIS (Draft International Standard) stage of development and its planned adoption will see some fundamental changes to how structured cabling is implemented within customer premises.
ISO/IEC 11801-6 cabling looks to support non user specific services and looks to establish communication pathways between these systems to share information with the added challenge that a number of these services require power from the same cable for the system to operate.
Wide band fibre has taken the next step for inclusion within ISO/IEC 11801 with the voting on the naming convention for the new optical fibre class concluding.
International voting for the naming convention revealed substantive support (72%) for the identifier OM5 which is in line with the Australian committee position.
OM5 Fibre will be optimized for operation between 850 to 953 nm and envisaged to deliver 100 Gb/s to 100 metres over two cores
Patch cords (balanced cords) are proving to be the weak point in the reliability of networks. Irrespective of the quality of structured cabling system, poorly performing and unreliable patch cords are having a devastating impact on infrastructure network operations along with the safety and security systems that run over them.
The performance obligations for patch cords goes well beyond just utilising appropriate cabling components to construct patch cords.
Work is entering the final stages on the draft for the Digital Hospital handbook.
The primary drivers for the handbook development are to help create a set of principles and recommendations to provide guidance in the design and implementation of new and refurbished digital hospitals.
The framework for the handbook is intended to help in the establishment of the seamless integration of:
The publication of the international standard ISO/IEC 30129 INFORMATION TECHNOLOGY – TELECOMMUNICATIONS BONDING NETWORKS FOR BUILDINGS AND OTHER STRUCTURES and the upcoming revision of AS/CA S009 INSTALLATION REQUIREMENTS FOR CUSTOMER CABLING (WIRING RULES), will mean the earthing/bonding requirements associated with telecommunication cabling systems within customer’s premises are likely to be substantially different from what we currently have.
CT-001 Australian Standards committee meeting held on the 19th October 2016 has agreed to the Standards and Technical reports to be submitted for project approval to Standards Australia for adoption as Australian and New Zealand standards and technical reports.
With the development and approval of IEEE 802.3bz 2.5/5.0 Gb/s over twisted pair, organisations are looking to capitalise on their investment in their existing infrastructure to achieve higher data rates without the need to upgrade infrastructure.
As we move into a digital disturbed world where IoT (Internet of Things) technologies change the way the traditional services are delivered, the existing safeguard that we have previously relied on may no longer be adequate to address the importance of communication technology systems on the delivery of safety, security and service delivery.
Day 4 of SC25 WG3 points of interest dealt primarily with one pair cabling in support of Ethernet and Remote power.
It would appear that work will start on 15m links as soon as ISO/IEC 11801-6 is published.
The initial work on one pair deployment outside of the 15m links is likely to start outside the ISO/IEC 11801 framework.
It looks like IoT is hitting the physical layer with data and power being the key deliverables.
Day 3 of SC25 WG3 addressed the proposed implementation of 25 GBits over existing infrastructure and the possible changes to the bonding standard ISO/IEC 30129 to put more emphasis on mesh grounding.
The key discussion related to how a one pair cabling that delivers both power and data can be incorporated in ISO/IEC11801 or associated documents.
The issue of heat rise in cables addressed today in ISO/IEC 14763-2 working group.
From the work undertaken by the group and supported by round robin testing from univeristies across Europe and US, Indications are that there are no fire risks on remote powered cables.
There are issues with cabling performance, particularly for performance elements that are effected by length.
Murray Teale (Technical Director of VTI Services) is in Germany this week to represent Australia at the ISO/IEC JTC 1/SC 25 WG3 meeting to address remote power fed devices.
0.75 A per conductor should make for an interesting debate.
Following a challenge to the validity of the Standards and additional requirements criteria Policy an internal and external review was undertaken against the requirements of AS/NZS ISO/IEC 17020.
The external party was a subject matter expert on ISO/IEC 17020 and ISO/IEC 11801.
NATA also reviewed the document on request.
The outcome of the internal and external review did not alter the requirements of the Policy however editorial content was changed.
On Tuesday 2nd August NATA carried out a technical audit of VTI Services.
Included in the audit was the confirmation of the validity of issuing reports to third parties on creation if the requirement has been specified within the additional requirements criteria.
The process utilised was deemed valid.
VTI Services additionally undertook to change its scope of accreditation to embrace infield services. These new services will be announced once the scope has been finalised.
