Q: What are the advantages of using 400G?

A:

  • Greater transmission density per RU: From single port rates of 100G to 400G, the transmission bandwidth per RU increases from 3.2-3.6T to 12.8-14.4T/RU.
  • Higher server connectivity density: Supports connections like 400G to 4x100G.
  • Reduced wiring complexity: For the same bandwidth, wiring is only a quarter of what it would be for 100G.
  • Lower power consumption: A 400G module consolidates four 100G modules, reducing operational costs.

Q: Can a 400G link have QSFP-DD on one end and OSFP on the other?

A: Yes. OSFP and QSFP-DD are just physical form factors of the modules. As long as the module type is the same (such as both being 400G-DR4 or 400G-FR4), OSFP and QSFP-DD can interoperate.

Q: Can modules packaged in QSFP format be used in QSFP-DD ports?

A: Yes. Modules packaged in QSFP format can directly be used in QSFP-DD ports; however, attention should be paid to configuring the port speed when using them.

Q: What is the maximum transmission distance of 400G modules?

A: The Walsun 400G module has a maximum transmission distance of 40km.

Q: What is the maximum power consumption of 400G modules?

A: The maximum power consumption of the Walsun 400G module is approximately 14W, though there are also low-power modules available with consumption around 12W.
