3 new IEEE 802.3 standard amendments for physical layer Ethernet functions published

IEEE and the IEEE Standards Association (IEEE-SA) today announced the publishing and availability of three standard amendments to IEEE 802.3, added in response to evolving industry requirements for new and emerging Ethernet applications.

“The IEEE 802.3 Ethernet Working Group continues to deliver on its commitment to ongoing standard improvements that deliver real-world operational scenarios, and meet challenges faced by data network operators worldwide,” commented David Law, chair, IEEE 802.3 Working Group.

The three newly published IEEE 802.3 standard amendments include:

• IEEE 802.3cb™-2018—IEEE Standard for Ethernet—Amendment 1: Physical Layer Specifications and Management Parameters for 2.5 Gb/s and 5 Gb/s Operation over Backplane.

• IEEE 802.3bt™-2018—IEEE Standard for Ethernet Amendment 2: Physical Layer and Management Parameters for Power over Ethernet over 4 pairs.

• IEEE 802.3cd™-2018—IEEE Standard for Ethernet—Amendment 3: Media Access Control Parameters for 50 Gb/s and Physical Layers and Management Parameters for 50 Gb/s, 100 Gb/s, and 200 Gb/s Operation.

As emphasized by 802.3 Working Group chair Law, “These refinements are essential to maintain Ethernet as the core technology driving advancements at data centers and throughout network infrastructures everywhere, as well as utilizing Ethernet to power the wide variety of sensors, actuators, cameras and other devices associated with the Internet of Things.”
