FAQs

Q: Is this DAC suitable for TOR switch to server connections?
A: Yes, 1 m passive DACs are commonly used for top-of-rack links with minimal latency and cost.

A: It is MSA-compliant and works with most QSFP+ 40G ports that support passive 40GBASE-CR4 DAC.

Q: Do I need any additional optics or modules?
A: No. The DAC includes QSFP+ connectors on both ends for direct-attach connectivity.
