400G QSFP-DD Optical Module Q&A

Q: Can a 400G QSFP-DD optical module be inserted into an OSFP port?

A: No, it cannot. This is because the packaging structures and dimensions of QSFP-DD and OSFP are different. For example, QSFP-DD uses a Quad Small Form-factor Pluggable Double Density design, while OSFP uses an Octal Small Form-factor Pluggable design. Additionally, the OSFP package is larger than the QSFP-DD package, making them incompatible.Furthermore, it is important to note that if your network devices are all QSFP-DD packaged, you must use QSFP-DD optical modules, QSFP-DD DAC, or QSFP-DD AOC.

Q: Can a 100G QSFP28 optical module be inserted into a QSFP-DD port?

A: Yes, it can. This is because the QSFP-DD package is backward compatible. Therefore, you can configure the QSFP-DD port to 100G and insert a 100G QSFP28 optical module for transmission. In this case, the link transmission rate will be 100G.
