What is the IEEE standard for QSFP28?
Knowledge Base + 2024.01.10

The IEEE standard for QSFP28 (Quad Small Form-Factor Pluggable 28) is IEEE 802.3bm. This standard defines the specifications for 100 Gigabit Ethernet (GbE) interfaces using a QSFP28 form factor. QSFP28 is a high-speed, compact optical transceiver module used in data center and telecommunication networks for transmitting and receiving data at rates of 100 gigabits per second (Gbps).

The IEEE 802.3bm standard specifies the physical layer specifications, including electrical and optical characteristics, for the 100 GbE interfaces based on QSFP28. It ensures interoperability and compatibility among different vendors' equipment that adheres to this standard, allowing for a consistent and reliable deployment of high-speed networking solutions.
