FAQ
Find answers to common product questions, or ask our technical team.
Where is this 800G OSFP to 2x400G QSFP112 AEC normally used?
It is typically used to connect one 800G OSFP switch port to two 400G QSFP112 ports on NICs or DPUs in AI, HPC, and high-density server access environments.
Does the 800G switch port need to support breakout mode?
Yes. The host device must support and be configured for 2x400G breakout mode before the two QSFP112 branches can operate as independent 400G links.
Why choose an AEC breakout cable instead of a passive DAC?
An AEC uses active signal conditioning and retiming to improve signal integrity, making it suitable for 5m to 7m short-reach copper links where passive DAC may not provide enough margin.
Can this cable replace optical modules for short 800G-to-400G links?
Yes. Within the supported reach, it can reduce the need for optical modules and fiber patch cords, helping lower cost, power consumption, and cabling complexity.

We tested the cable right after receiving it, and the link came up quickly. Build quality looks good, and the connectors feel solid.

The length was just right for our rack cabling. It has been running for a few days with no drops, more stable than expected.

Used it to replace an older DAC, and the link recovered quickly. It has been running smoothly so far with no obvious errors.
