FAQs

Q: What is the difference between passive and active DAC?
A: Passive DACs have no signal conditioning and rely on the host port, offering lower cost and power. Active DACs include electronics to extend reach or improve signal integrity.

Q: How do I confirm device compatibility?
A: Check your device’s SFP+ port specifications and compatibility matrix to ensure support for passive SFP+ DAC cables of 0.5 m length.

Q: Is this suitable for stacking links?
A: If your platform supports stacking over SFP+ DAC connections, this cable can be used within the supported reach.
