Can I use a QSFP-DD 400G DR4 module on one end and interconnect it with a QSFP112 DR4 or OSFP 400G DR4 module on the other end?

Yes, QSFP-DD/OSFP/QSFP112 only describes the physical form factor of the module. All three modules use 4x100G PAM4 for optical modulation, so they can be interconnected.

Is the QSFP112 port backward compatible?

The QSFP112 port is backward compatible with traditional QSFP 40G (4x10G), 100G (4x25G), and 200G (4x56G-PAM4) modules and cables.

What is the maximum transmission distance of the Q112-400G-DR4 optical module?

When paired with single-mode MPO/MTP fiber jumpers, it can achieve a maximum transmission distance of 500m.

Questions & Answers

Ask a Question

Is this module compatible with the BlueField-3 400G DPU?

It is compatible, ensuring that the DPU port type is QSFP112.

Can the QSFP112 400G DR4 module be used on an OSFP port?

OSFP and QSFP112 are two completely different form factors, and the QSFP112 cannot be used on an OSFP port.

What is the difference between Q112-400G-DR4 and QDD-400G-DR4/OSFP-400G-DR4?

The main difference lies in the packaging. QSFP-DD uses 8x50G/lane, while QSFP112 and OSFP use 4x100G/lane. Additionally, the OSFP form factor is larger than that of QSFP-DD and QSFP112.
