What you need to know now for the future of your networkWelcome to the thirteenth edition of the Standards Advisor. This report is issued quarterly and provides updates on the standards relevant to the structured cabling industry, and the impact they have on your network design, planning and operations.

This summary represents standards meetings held during the fourth quarter of 2016 and reports on activities from all aspects of the cabling industry. These activities range from the applications standards (IEEE 802.3 and 802.11 and T11—Fibre Channel) to the cabling standards (ANSI/TIA, ISO/IEC, CENELEC) and, finally, cover new developments in the world of multisource agreements (MSAs).

ISO/IEC JTC1/SC25 WG3: No face-to-face meetings were held during the quarter.

The Standards AdvisorIssue 13 • Quarter 4, 2016

The 62nd ISO/IEC JTC1/SC25 WG3 meeting will be held January 16-20, 2017 in Singapore.

TIA TR-42: Philadelphia, PA USA 3-7 October, 2016

1 TR42.1 Generic Cabling

• TR42.1 discussed and resolved all comments on TIA-942-B data center standard.

• Comments to delete wideband MM fiber as a recommended media for backbone and horizontal were not accepted

• Direct attach cabling is allowed as an option in the data center standard but is limited to 7 m only within the same rack/cabinet or adjacent racks/cabinets. It is also identified as not structured cabling so designers are aware of its limited flexibility in accommodating MACs.

• Comments on ANSI/TIA-1179-B healthcare facilities were resolved and the document recirculated for another industry ballot.

– Comments to add Wideband MM fiber as a recommended media for backbone and horizontal cabling were accepted.

• A new project to address telecommunications cabling for places of assembly was initiated with the intent of providing additional guidelines for stadiums, theatres, places of worship, etc.

2 TR42.3 Pathways and Spaces

• Discussed and resolved comments on the TIA-569-D-1 addendum containing updated guidelines for temperature and humidity for telecommunications spaces based on ASHRAE 2015 fourth edition. The new guidelines specify 1) Temperature: 5 – 35 ºC (41 – 95 ºF) dry bulb, 2) Humidity range, noncondensing: 8% RH to 28 ºC (82 ºF) DP and 80% RH

• These new guidelines broaden the ranges for temperature allowed with the intent of lowering the HVAC costs for distributor rooms, equipment rooms, and entrance facilities.

• TR42.3 also discussed many comments on the new TIA-569-D-2 addendum on guidelines for pathways used for remote powering.

3 TR42.5 Definitions

• Discussed and resolved several definitions that are needed for new TIA document. The committee also maintains symbols used in the documents

and is also responsible for the TIA TSB-440 containing legacy optical fiber definitions and explanations.

4 TR42.6 Administration

• Discussed progress of ISO 18598 AIM standard to FDIS status and plans to adopt this document as an ANSI standard with cover sheet showing TIA preferences for the naming of identifiers. The adoption of this standard will reduce duplication of effort and also result in improved harmonization between ISO and TIA.

• Revising ANSI/TIA-606-B standard and resolved all comments to send this document out for another industry ballot.

5 TR42.7 Copper cabling systems and components

• Comments on TIA TSB-5021 cabling in support of IEEE 2.5G/5GBASE-T were resolved and the document advanced to a default ballot.

• Comments on TIA TSB-184-A cabling in support of remote powering were resolved and the document advanced to a default ballot

• Advanced to a default ballot and will be published if no technical comments are received during this ballot.

8 TR42. 11 Fiber cabling systems, TR42. 12 Fiber cable and TR42. 13 Fiber Metrology

• Did not meet due to conflict with IEC 86 meeting in Frankfurt, Germany.

9 TR42.16 Bonding and Grounding

• Resolved all comments on TIA-607-C-1 addendum to specify a telecommunications bonding and grounding infrastructure for multi-tenant buildings. The challenge is to provide a basic common infrastructure for the whole building, with guidelines for the attachment of individual bonding infrastructure as each tenant space is built out.

• This document will cover a gap where it is not clear how to connect and unify multi-tenant bonding infrastructures.

10 TR42 plenary

• Discussed the activities of its subcommittees and acted on several motions from the sub-committees. TR42 discussed and approved the following liaison letters:

– IEEE 802.3 regarding cabling specifications between 60 C and 90 C – NFPA 70 regarding interest in participating in the NEC Correlating committee task group to review and revise articles 725.144 and 840.160 on regulations for remote power delivery over Class 2 circuits

– IEEE 802.3 regarding TIA TR42 activities and plans for 1-pair cabling• In response to a liaison letter from IEEE 802.3 outlining the status of

several 1-pair projects under development, the plenary approved the formation of joint task group of TIA TR42.1, 42.7, 42.9 membership co-chaired by the respective committee chairs to study 1-pair cabling and come back with recommendations.

The next meeting of TIA TR42 committees is scheduled for 6-10 February, 2017 in Philadelphia, PA USA.

FC-PI-7 [64GFC & 256GFC]

• Additional recommendations were made to FC-PI-7 Marketing Requirements Document (MRD):

– 64GFC connection loss allocation of 1.5dB, 256GFC connection loss allocation of 1.0dB

– 64GFC should be a higher priority than 256GFC – WideBand-MMF (OM5) can be used for FC-PI-7 MMF links.

• MMF variants for 64GFC were reviewed including a transceiver parameter comparison of 57.8Gbps FC versus 53.125Gbps Ethernet

PAM4. As a result, the target optical uncorrected BER was modified from 2.4e-04 to 1.09e-4. The group made an initial attempt to define transmitter and receiver parameters.

• Motion was passed to include 64GFC PCS/FEC architecture (RX processing and TX bit ordering diagram) in FC-FS-5.

The next meeting of INCITS/T11 is scheduled for 6-10 February, 2017 in Raleigh, NC, USA

IEEE 802.3 Ethernet Meeting: San Antonio, Texas, USA 8-November, 2016

1 IEEE Std. 802.3bz-2016 2.5G/5GBASE-T on up to 100m of Category 5e or better cabling

• Published by the IEEE-SA. The document is available for purchase. Pre-standard (NBASE-T) products are in the market, and interoperability has been demonstrated with IEEE Std 802.3bz-2016 pre-market products in an Ethernet Alliance/NBASE-T Alliance plugfest.

2 IEEE 802.3bt 4 pair Power over Ethernet

• Continues development on track, and continues the Working Group ballot phase. The document is technically complete and no new features are being added. The IEEE 802.3bt standard currently references TIA TSB-184-A and ISO/IEC TR 29125 for cabling requirements. The IEEE 802.3bt standard is expected to complete Working Group Ballot by March 2017, and be approved at an IEEE standards board meeting cycle in the first quarter of 2018.

Single Twisted Pair Copper Standards

3 IEEE P802.3bu Single-pair power over data lines (PoDL)

• Completed sponsor ballot. The Task Force met in November to re-affirm the draft’s position on the Standards Board agenda. IEEE Std 802.3bu-2016 was approved by the Standards board on 7 December 2016, and is currently being prepared for publication.

4 IEEE P802.3cg 10 Mbps Single-Twisted-Pair Ethernet

• The 10 Mbps Single Pair Ethernet, including optional powering, met in November and completed its project documentation for approval of the PAR and the project. The project objectives cover industrial, automotive, and building automation use cases, with two dominant, but different application reaches, one up to 15m, and one of approximately 1km. The Study Group will also consider associated powering, including possible augmentation of the single-pair powering developed in 802.3bu (PoDL). The media objectives of the project include:

– Define the performance characteristics of a link segment and a PHY to support operation over this link segment with single twisted pair supporting up to four inline connectors using balanced cabling for up to at least 15 m reach.

– Define the performance characteristics of a link segment and a PHY to support point-to-point operation over this link segment with single twisted pair supporting up to 10 inline connectors using balanced cabling for up to at least 1 km reach

5 IEEE 802.3 MultiGigabbit Automotive Study Group

• Approved a new study group for MultiGigabit Automotive Ethernet. This study group is currently forming the project objectives targeted at automotive applications in excess of 1Gbps. The project scope may address a wide range of media types and possibly multiple rates, including 2.5Gbps, 5Gbps and 10Gbps. Ad hoc meetings have begun, and the project has discussed foil-twisted-pair, coax, plastic-optical-fiber, and glass fiber media at automotive distances, typically around 10m. It is expected that the project scope will rapidly tighten when the first official study group meeting takes place in January 2017.

6 IEEE P802.3bs (400GE and 200G on SMF)

The IEEE 802.3bs Task Force was formed in Mar 2014 to specify 400G Ethernet. Objectives to support 200G over SMF were added in March

2016 (transferred from 802.3cd). Some of the important project objectives are as follows

1. Support full-duplex operation only. 2. Provide 200G physical layer specifications which support link

distances of at least 500m, 2km, and 10km over SMF 3. Provide 400G physical layer specifications which support link

distances of at least 100m over MMF as well as at least 500m, 2km, and 10km over SMF

The WG ballot of D2.1 received 91.7% approval with 161 comments of which 129 were technical. All comments were resolved and D2.2 was forwarded for another WG ballot. An analysis of OM5 fibers made by a cabling company attempted to raise concerns associated with channel compliance, but the attempt was not well received. OM5 remained a recognized medium supporting 400G operation.

7 IEEE 802.3ca Task Force (Next Generation EPON)

More technical presentations were discussed, but few motions were submitted. A few minor decisions were made and the timeline was pushed back 6 months to April 2019. To decide a wavelength plan the group needs to decide whether:

1. the 25G channel should use TDM or WDM coexistence with 10G EPON2. SOAs have sufficient gain to work in the O-band

While a wavelength plan wasn’t decided, the choices were further narrowed. Two flavors of wavelength plans have been debated called “1+3” and “1+4.” With 1+3 the 25G wavelength is chosen to match the 3 other wavelengths used in 100G. With 1+4 a low-cost solution is chosen for 25G that is independent of the wavelengths chosen for 100G. A motion excluding the 1+4 plan passed.

8 IEEE P802.3cc (25 Gb/s Ethernet PMD(s) for single-mode fiber)

This Task Force is to specify 25G SMF links for large-scale data centers and next generation enterprise backbone applications. 802.3by already defines 25G Ethernet for operation over backplane, twinax and MMF. The addition of SMF support would provide a full ecosystem for 25G Ethernet. In this meeting, the TF review of D1.1 received 20 comments of which 15 were technical. All comments were resolved and D2.0 will be prepared for WG ballot. An approved standard is planned for Oct 2017.

9 IEEE P802.3cd (50G, next gen 100G and 200G)

This Task Force is specifying 50G, 100G and 200G solutions for future generation server-to-switch and switch-to-switch applications. Optical fiber objectives for 802.3cd include:1. Define a single-lane 50 Gb/s PHY for operation over: a. MMF up to at least 100 m b. SMF up to at least 2 km c. SMF up to at least 10 km2. Define a two-lane 100 Gb/s PHY for operation over: a. MMF up to at least 100 m3. Define a single-lane 100 Gb/s PHY for operation over: a. SMF up to at least 500 m4. Define a 200 Gb/s PHY for operation over: a. MMF up to at least 100 m Proposals have been accepted for all of these objectives and the draft completed initial Task Force review.

CO-110182.3-EN (11/17)

The multimode solutions consist of a family that employs one, two and four fibers in each direction for 50GBASE-SR, 100GBASE-SR2 and 200GBASE-SR4 respectively. The single-mode 100 Gb/s solution, called 100GBASE-DR, combines two 50G electrical lanes into a single 100G optical stream. All PHYs will employ PAM4 signaling in which each symbol carries two bits of information.

Since the specs and naming of WBMMF(OM5) had been determined by cabling standards, the Task Force agreed to list the new fiber as a supported medium for 50G, 100G and 200G MM links.

The next IEEE 802.3 meeting will be the week of 10 January, 2017 in Huntington Beach, CA USA.
