FAQs

Q: Is it universally compatible?
A: It fits SFP+ ports that support 10GBASE-ER/CWDM optics; confirm with your platform’s documentation.

Q: Do I need a 1590 nm module at the far end?
A: Yes, both ends must use the same 1590 nm CWDM wavelength.

Q: What type of cable is required?
A: Single‑mode fiber (OS2) with LC duplex connectors.

Q: Does it have DOM/DDM?
A: Yes, it supports digital diagnostics monitoring.

Q: Can I link it with a different wavelength ER optic?
A: No. Wavelengths must match for a link to establish.
