2023.12.01

Yes, QSFP (Quad Small Form-factor Pluggable) and QSFP28 are compatible. QSFP28 is backward compatible with QSFP, so a QSFP28 transceiver can be used in a QSFP port. However, it's important to note that the speed and capabilities of the transceiver will be limited to the specifications of the QSFP port.
