What is the difference between Q112-400G-DAC and QDD-400G-DAC?

The main difference between Q112-400G-DAC and QDD-400G-DAC lies in the number of channels on the electrical side. Q112-400G-DAC has a 4x100G PAM4 electrical side, while QDD-400G-DAC has an 8x50G PAM4 electrical side.

Are QSFP112 ports backward compatible?

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

What is the difference between 400G ACC and 400G DAC?

400G DAC is a passive copper cable without active components in the connectors, used for short-distance connections within 2 meters. On the other hand, 400G ACC is an active copper cable with active components, allowing cable lengths to be extended up to 7 meters.

Questions & Answers

Ask a Question

Can it be compatible with the NVIDIA MCX755106AS-HEAT network card?

The network card port type is dual-port 200G QSFP112, and this DAC cable can be compatible through speed reduction.

What is the maximum distance that the 400G Q112 DAC can provide?

It can provide up to 3 meters.

Can QSFP112 400G cables be used on OSFP ports?

OSFP and QSFP112 are two completely different form factors, and QSFP112 cannot be used on OSFP ports.
