FAQs

Q: Is wavelength matching required across the link?
A: Yes. Both ends must use the same 1490 nm CWDM 10G optics and compatible link budgets.

Q: Can it pass through passive CWDM mux/demux units?
A: Yes. It is designed for CWDM grids and works with passive CWDM components.

Q: Does it support DOM for monitoring?
A: Yes, digital diagnostics (DOM/DDM) are supported.

Q: Which fiber type and connector are needed?
A: Single‑mode OS1/OS2 fiber with LC duplex connectors.
