FAQs

Q: Is this a passive or active 100G cable?
A: It is a passive twinax DAC with ultra‑low latency and no external power requirement.

Q: What is the supported reach?
A: This model is 1 meter, suitable for same-rack connections.

Q: Will it work with any QSFP28 100G port?
A: It is MSA and IEEE 802.3bj compliant for interoperability with standards-based QSFP28 100G ports.

Q: Do I need optical transceivers with this cable?
A: No. DACs plug directly into QSFP28 cages and do not require separate optics.

Q: Typical applications?
A: Top-of-rack 100G switch-to-switch or switch-to-server links where ultra-low latency and low cost are desired.
