FAQs

Q: What environments is this cable best for?
A: Top-of-rack and adjacent-rack InfiniBand HDR installations needing 400G to 4×100G breakout.

Q: Is this cable passive?
A: Yes. It is a passive twinax copper assembly.

Q: Can it be used for Ethernet fabrics?
A: It is designed for HDR. Ethernet use depends on device support for OSFP-to-QSFP56 DAC breakout—check your platform’s documentation.

Q: How far can it reach?
A: This model supports up to 2 meters.

Q: Are separate transceivers needed?
A: No. The DAC plugs directly into OSFP and QSFP56 cages.
