FAQ
Ask a QuestionFind answers to common questions about our products.
Where is this AICPLIGHT 800G OSFP to 2x400G QSFP112 ACC normally used?
It is typically used to connect one 800G OSFP switch port to two 400G QSFP112 ports on NICs or DPUs. This is common in AI, HPC, and high-density server access environments.
Does the 800G switch port need to be configured for breakout?
Yes. The switch port must support 2×400G breakout and be configured correctly before the two QSFP112 branches can operate as independent 400G links.
What is the difference between this ACC cable and a passive copper breakout cable?
A passive DAC has no active components and is best for very short links. This ACC integrates active equalization to help maintain signal quality over longer short-reach copper connections, while keeping lower power and cost than AEC solutions.
Can this cable replace optical modules and fiber for short 800G-to-400G links?
Yes, for short-reach switch-to-NIC or switch-to-DPU connections, this ACC can reduce the need for optical modules and fiber patch cords. It helps lower link cost, power consumption, and cabling complexity inside or between nearby racks.

Questions & Answers Title
Ask a questionWe put the cable on our test rack first, and the whole process was smooth. No strange alerts came up, and the performance matched what we expected.
This AICPLIGHT cable held up well during our burn-in test. We haven’t seen any unusual bit errors so far.
We compared a few options and picked this one mainly for price and lead time. It worked as expected once installed.
