Can QSFP-DD 400G transceiver be used directly in OSFP ports?

No. QSFP-DD and OSFP are two different form factors with different physical dimensions. OSFP is slightly larger than QSFP-DD and cannot be directly adapted.

Can I interconnect a QSFP-DD 400G SR8 module at one end and an OSFP 400G SR8 module at the other?

Yes, QSFP-DD and OSFP only describe the physical form factor of the module. Both modules are 8x50Gb/s modulated and can be interconnected using multimode MPO/MTP 16 APC patch cords.

Questions & Answers

Ask a Question

What is the modulation mode of QSFP-DD 400G SR8 transceiver?

QDD-400G-SR8 transceiver adopts 8x50Gb/s PAM-4 modulation, "S" is the abbreviation of short, which means short distance transmission, and "8" means there are 8 optical channels.

What is the max transmission distance of the QDD-400G-SR8 transceiver?

When matched with OM3 multimode fiber, the farthest transmission distance is 70m; with OM4 multimode fiber, the farthest transmission distance can reach 100m.

What are the connection options for the 400G QSFP-DD SR8 transceiver?
