Questions & Answers

Ask a Question

Can OSFP ports use modules in QSFP-DD form factor, such as Arista QDD-400G-LR4?

OSFP and QSFP-DD are two completely different form factors, so QSFP-DD optical modules like Cisco QDD-400G-FR4-S, QDD-400G-SR8-S, QDD-400G-LR4-S or QDD-400G-DR4-S all these optical transceivers cannot be used in OSFP ports.

Can a 400G link with one end using a Arista QDD-400G-LR4 optical module and the other end using Arista OSFP-400G-FR4 OSFP be interconnected?

Yes, OSFP and QSFP-DD are just physical form factors for modules, and as long as the modules are of the same type (such as both being 400G-DR4 or 400G-FR4), OSFP(Arista OSFP-400G-FR4) and QSFP-DD(Arista QDD-400G-LR4) modules can be interconnected.

Can the Arista QDD-400G-LR4 modules be used on QSFP-DD ports?

Yes, Arista QDD-400G-LR4 modules can be directly used on QSFP-DD ports, but it is important to configure the port speed appropriately when using them.

What is the maximum power consumption of a 400G module?

The maximum power consumption of the 400G modules provided by NADDOD is 14W (QDD-400G-ER8), and there are also low-power ER4（QDD-400G-ER4 lite）modules available for distances up to 40KM, with a power consumption of 12W.

Can I use 400G LR4 for my fiber optic link of 8km?

Although the maximum transmission distance of 400G LR4 is 10km, the actual transmission distance needs to be judged according to the loss size of the fiber optic link, which is mainly related to the light emitting power of the module, the receiving sensitivity, and the link loss value.

What is the difference between 400G LR4 and 400G LR8?

The 400G-LR4 is 4X100G on the optical path side, and the 400G-LR8 is 8X50G on the optical path side, which leads to a difference in the number of lasers they use, and a difference in power consumption and cost.

Is there any requirement for the switch to use 400G LR4?

Although 400G LR4 is a long range module, its power consumption is less than 10w, which can be supported by most of the switches (some switch ports have power consumption limitations, usually 12w).

Can 400G LR4 be interconnected with 100G LR4?

No. Even though they are both LR4 and have the same transmission distance and number of channels, their technical standards are so different that they cannot be interconnected.

What is the difference between QSFPDD LR4 and QSFP112 LR4?

QSFPDD LR4 signals 8X50G on the electrical side, while QSFP112 has 4X100G on the electrical interface, but they have the same standard in the optical path and can be used together.
