The IEEE has released a series of four new standards that will address a variety of speeds, including 1 Gbps, 25 Gbps, and 40 Gbps. This new group of standards include: IEEE 802.3bp, IEEE 802.3bq, IEEE 802.3br, and IEEE 802.3b standards. Ethernet players will be able to respond to a host of applications such as hyperscale data centers, enterprise, cloud computing, automotive, Internet of Things (IoT), and Power over Ethernet (PoE).
Addressing 1 Gbps operations over single twisted pair copper, IEEE 802.3bp defines physical layer (PHY) specifications (including optional single-pair auto negotiation and Energy Efficient Ethernet) and parameters for full-duplex 1 Gbps Ethernet operating in harsh environments found in automotive and industrial applications. With IEEE 802.3bq, the IEEE has created a foundation for 25 Gbps and 40 Gbps twisted pair solutions with auto-negotiation capabilities and Energy Efficient Ethernet (EEE) support for data center applications.
Designed to meet the needs of the industrial control system manufacturers and the automotive market, IEEE 802.3br specifies a pre-emption methodology for time-sensitive traffic. Finally, IEEE 802.3by introduces a cost-optimized 25 Gbps PHY specifications for single-lane server and switch interconnects for data centers. Release
