FAQs

Q: Is this cable vendor-locked?
A: Programming and vendor-locking vary by device ecosystem. Verify compatibility with your switch/server vendor before purchasing.

Q: How far can a passive 200G DAC reach?
A: Passive DACs are intended for very short distances, typically up to 1–3 meters depending on gauge and device signal tolerance. This unit is 1 meter.

Q: Do I need special transceivers?
A: No separate optics are required. The QSFP56 connectors on the cable plug directly into QSFP56 200G ports.
