Q: What are the common types of 400G QSFP-DD optical modules available on the market?

A: Common types of 400G QSFP-DD optical modules in the market include QSFP-DD SR8, QSFP-DD DR4, QSFP-DD FR4, QSFP-DD FR8, QSFP-DD LR4, QSFP-DD LR8, and QSFP-DD ER8 optical modules.

Q: What are the advantages of using 400G?

A: Higher transmission density per RU: From single-port speeds of 100G to 400G, the transmission bandwidth per RU increases from 3.2-3.6T to 12.8-14.4T.

Greater server connection density: Supports connections from 400G to 4x100G.

Reduced wiring complexity: With the same bandwidth, wiring requirements are only 1/4 compared to 100G.

Lower power consumption: One 400G module consumes less power than four 100G modules, reducing operational costs.

Q: What interface types do 400G modules support?

A: Duplex LC interface, similar to 100G-CWDM4, 40G-LR4 modules. LR4, ER4, ER8 modules use duplex LC interfaces.

MPO12 interface (APC), similar to 100G-SR4, 100G-PSM4 modules. 400G-DR4, XDR4, PLR4 modules use MPO12 interfaces.

MPO16 interface (APC), 400G-FR4/400G-SR8 modules use eight fibers for transmission and eight fibers for reception, totaling 16 fibers for 400G transmission.

Q: Can you use an OSFP optical module on one end of a 400G link and a QSFP-DD optical module on the other end?

A: Yes. OSFP and QSFP-DD describe the physical size of the optical modules. As long as the protocol standards are the same (i.e., both ends of the link are using 400G-LR4 or 400G-FR4, etc.), OSFP and QSFP-DD optical modules can be mutually compatible.
