FAQs

Q: What distance can this module support?
A: Up to 70 km over 9/125 um single-mode fiber, subject to link budget and fiber quality.

Q: Do I need a matching wavelength on both ends?
A: Yes. Both ends must use the same CWDM wavelength when connected through a CWDM MUX/DEMUX pair.

Q: Is it compatible with standard Gigabit Ethernet (802.3z)?
A: Yes. It is compatible with 1000BASE-ZX reach for extended distances over SMF.

Q: Does it support DOM/DDM monitoring?
A: Yes, for key diagnostics such as temperature and optical power levels.

Q: Can this be inserted while the switch is powered?
A: Yes. It is hot-swappable.
