FAQs

Q: Is this compatible with 1G switch SFP ports?
A: Yes, it is designed for 1G SFP ports that accept CWDM optics.

Q: What fiber type should I deploy?
A: Use OS2 single‑mode fiber with LC connectors.

Q: Can I mix different reach optics on the same mux?
A: Yes; ensure overall link budget accommodates mux/demux insertion loss and path attenuation.

Q: Does it support hot‑swap?
A: Yes, it is hot‑swappable in compliant SFP ports.

Q: Is this a duplex optic?
A: Yes, it uses two fibers (Tx/Rx) with LC duplex.
