FAQs

Q: Is this cable active or passive?
A: It is a passive twinax DAC; no power is required.

Q: Will it work at 25G in SFP28 ports?
A: It requires SFP56-capable cages. Some platforms may support fallback to 25G when both ends allow dual-rate operation, but check your platform release notes.

Q: What standard does it follow?
A: It is compliant with IEEE 802.3cd 50GBASE-CR and the SFP56 MSA.

Q: What is the maximum reach?
A: 0.65 meters for this specific assembly.

Q: Is vendor coding required?
A: Most enterprise switches require correct EEPROM coding; ensure code is suitable for your platform.
