Technical Specifications

FAQs

Q: Is this compatible with my switch or router?
A: It is intended for SFP+ ports that support 10GBASE-ER/CWDM optics; consult your platform’s compatibility list.

Q: Do both ends need to be 1550 nm?
A: Yes. Use a matching 1550 nm CWDM SFP+ at the far end.

Q: What fiber should I use?
A: Single‑mode OS2 fiber with LC duplex connectors is recommended.

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

Q: Can it interop with standard 10GBASE-ER optics?
A: Only if the wavelengths match; a non‑CWDM ER at another wavelength will not link.
