Frequently Asked Questions
Q: Which lane of the QSFP+ port does the adapter utilize?
A: The adapter uses lane 1 of the QSFP+ connector, with the remaining three lanes unconnected.
Q: Is this adapter compatible with all SFP+ transceivers?
A: Yes, the adapter works with all MSA-compliant SFP+ and SFP transceivers from major manufacturers.
Q: What is the difference between standard and extended temperature models?
A: The extended temperature model (MAM1000A-QSA_E) operates from -10°C to 85°C, while the standard model operates from 0°C to 70°C.
Q: Does the adapter require external power?
A: No, the adapter operates passively without external power requirements.
