Below are some highlights of active projects from recent committee meetings. For a comprehensive list of the latest updates from IEEE, TIA, and ISO committees, read the Quarter 2 Leviton Standards Report (pdf).
Published Amendments to IEEE 802.3™ - 2018
IEEE 802.3ca-2020 - Ethernet Amendment 9: Physical Layer Specifications and Management Parameters for 25 Gb/s and 50 Gb/s Passive Optical Networks
IEEE 802.3ch-2020 - Ethernet Amendment 8: Physical Layer Specifications and Management Parameters for 2.5 Gb/s, 5 Gb/s, and 10 Gb/s Automotive Electrical Ethernet
IEEE P802.3da 10 Mb/s Single Pair Multidrop Segments Enhancement - This project was elevated to a Task Group in June 2020, so the July plenary meeting is the first meeting of the task group. The focus of the meeting will be to identify major work items, owners, and to establish a timeline.
This project supports 10 Mb/s single pair Ethernet mixing segments (multidrop), including optional power delivery supporting multiple powered devices.
IEEE P802.3db 100 Gb/s, 200 Gb/s, and 400 Gb/s Short Reach Fiber - This project was elevated to a Task Group in June 2020, so the July plenary meeting is the first meeting of the task group. No timeline has been created yet.
This project supports 100 Gb/s, 200 Gb/s, and 400 Gb/s optical interfaces for server attachment and other intra-data center applications using 100 Gb/s signaling over optical fiber. The project objectives include a reach of 50 m over multimode fiber using 1 pair (100 Gb/s), 2 pairs (200 Gb/s) or 4 pairs (400 Gb/s).
IEEE P802.3ct 100 Gb/s over DWDM Systems - Draft 2.0 closed in June 2020 with roughly 140 comments. Comment resolution will occur during conference calls in July, including during the July 2020 plenary meeting. The goal is to complete all technical changes by September 2020 in preparation for circulating draft 3.0. The target publication date remains September 2021.
This standard supports 100 Gb/s operation on a single wavelength capable of at least 80 km over a DWDM system.
IEEE P802.3cu 100 Gb/s and 400 Gb/s over Single-Mode Fiber at 100Gb/s per Wavelength - Draft 2.2 closed in June 2020 with 21 comments. Comments were minor and were withdrawn with plans to resubmit for draft 3.0, which was circulating just prior to the July 2020 plenary meeting. The target publication date is December 2020.
This standard supports 100 Gb/s (single wavelength) or 400 Gb/s (4 wavelength) operations over single mode optical fiber for distances up to 10 km.
IEEE P802.3cw 400 Gb/s over DWDM Systems - No drafts have been circulated yet. Because the 400 Gb/s work will draw heavily from the 100 Gb/s work, 802.3ct must be technically stable before a draft of 802.3cw can circulate. Although no timeline has been officially adopted, the current estimated publication date is June 2022.
This standard supports 400 Gb/s operation on a single wavelength capable of at least 80 km over a DWDM system.

TR-42.1: Commercial Telecommunications Cabling - A first committee ballot for ANSI/ TIA-862-C (Intelligent Building Systems) will circulate for review at the October 2020 meeting. The primary focus for this revision is to add Single Pair Ethernet (SPE) as a recognized media, along with necessary updates for cabling topologies.
TR-42.7: Telecommunications Copper Cabling Systems - A first industry ballot for TIA-568.5 (single-pair components) will circulate for review at the October 2020 meeting.
A second committee ballot for ANSI/TIA-5071 (SPE field testing) will circulate for review at the October 2020 meeting.
The committee was not able to address ANSI/ TIA-568.6 (Single Pair Multidrop) at the June 2020 meeting. The July 2020 TR42.7 interim meeting will prioritize this topic before other business.
TR-42.9: Industrial Telecommunications Infrastructure - Task Group meetings have begun to develop content for ANSI/TIA-568.7 (SPE for industrial). This document will complement the 568.5 standard and will focus on SPE cabling for M2I2C2E2 and M3I3C3E3 environments.
TR-42.11: Optical Fiber Systems - A first committee ballot for ANSI/TIA-568.3-E (optical fiber components) will circulate for review in October 2020.
ISO/IEC JTC1/SC25 WG3 - Customer Premises Cabling
Single-Pair Ethernet (SPE)
11801-1 AMD1 (Generic): Specifies cabling channels and link classes to generically support single-pair applications. A 2nd Committee Draft (CD) will be circulated for review at the September 2020 WG3 meeting. The target publication date is May 2021.
11801-3 AMD1 (Industrial): Specifies cabling channels and link classes to support single pair applications in an industrial environment. The closing date for the Draft Amendment (DAM) occurred after the February 2020 WG3 meeting, so comments will be reviewed in September 2020. The target publication date is March 2021.
11801-6 AMD1 (Distributed Building Systems): This amendment will specify cabling channels and link classes to support single pair applications for intelligent building environments. A Working Draft (WD) was reviewed at the February 2020 WG3 meeting. A 1st Committee Draft (CD1) will be circulated for review at the September 2020 WG3 meeting. A target publication has not been established.
