FAQs

Q: What is the difference between passive and active DAC?
A: Passive DACs have no signal conditioning and consume virtually no power; active DACs include electronics to extend reach or improve signal integrity.

Q: Can this DAC be used between racks?
A: At 0.5 m it is intended for within the same rack. For longer distances, consider AOC or optical transceivers with SMF/MMF.

Q: Is special configuration required on 25G ports?
A: Typically plug-and-play; ensure the port is set to 25G and enable FEC if recommended by your switch/NIC for 25GBASE-CR.
