FAQs

Q: Does this cable require optical modules?
A: No. It is an integrated QSFP28 copper DAC and does not require separate optical transceivers.

Q: Is it cross-platform compatible?
A: It adheres to MSA standards, but some equipment enforces vendor coding. Verify compatibility with your platform.

Q: What are typical applications?
A: Short-reach 100G links such as switch-to-server, switch-to-switch, and leaf–spine fabrics.

Q: Is it breakout-capable?
A: No. This is a straight 100G QSFP28-to-QSFP28 cable. Use a breakout cable for 4x25G.

Q: Is it fiber or copper?
A: Copper twinax. It is a passive DAC, not a fiber optic assembly.
