FAQs

Q: Is this module compatible with my switch/router?
A: It works in 10G SFP+ ports that support 10GBASE-ER/DWDM optics and DOM. Check your platform’s transceiver compatibility list.

Q: What fiber and connector do I need?
A: Use OS2 single-mode fiber with a duplex LC connector.

Q: Can I use this for short links?
A: Yes, it can operate on shorter spans. If receiver overload occurs, add appropriate optical attenuation.

Q: Does it support DOM/DDM?
A: Yes, digital optical monitoring is supported for real-time diagnostics.

Q: Do I need a DWDM mux/demux?
A: For multi-wavelength DWDM transport, use a DWDM mux/demux that includes the 1540.56 nm channel.
