IEEE 802.3 Enhancements to Point-to-Point Single Pair Ethernet Study Group

This Study Group’s work is completed.  Following SASB approval of the IEEE P802.3de PAR, initiating that project, beginning 9/29/2021, the remaining work, has transitioned to the Greater than 10 Mb/s Long-Reach SPE Study Group.

For information on the IEEE P802.3de Project (official title: Enhancements to the MAC Merge function and the Time Synchronization Service Interface (TSSI) to include Point-to-Point 10 Mb/s Single Pair Ethernet) please see

For information related to the Greater than 10 Mb/s Long-Reach SPE Study Group, please see .


The IEEE 802 LMSC Executive Committee has chartered a Study Group under the IEEE 802.3 Ethernet Working Group to develop a Project Authorization Request (PAR) and Criteria for Standards Development (CSD) responses for Enhancements to point-to-point Single Pair Ethernet to:
1. Support Time-Sensitive Networking (TSN), and
2. Support increasing traffic and speed needs with long reach point-to-point higher-speed single-pair PHYs
