FAQs

Q: What hardware is this compatible with?
A: Hardware with 400G HDR OSFP ports that support DAC breakout to QSFP56, and endpoints with QSFP56 100G ports.

Q: Is it active or passive?
A: Passive twinax copper (no active components).

Q: Is Ethernet supported?
A: It targets InfiniBand HDR. Ethernet operation depends on platform support for OSFP-to-QSFP56 DAC breakouts—verify with your vendor documentation.

Q: What is the reach?
A: 1.5 meters for this model.

Q: Are optical transceivers required?
A: No. This is a direct-attach copper assembly.
