Frequently Asked Questions

Q: Can I use this BIDI B Side module alone?
A: No. It must be used with a BIDI A Side (1270/1330nm) module on the opposite end to create a working link.

Q: Will this show as an unknown device in UniFi Controller?
A: No. It is fully programmed to avoid compatibility warnings and support normal monitoring in UniFi Network Controller.

Q: What fiber cable do I need?
A: One strand of 9/125μm OS2 single-mode fiber with LC simplex connectors.

Q: Is this hot-pluggable on UniFi switches?
A: Yes, fully hot-pluggable; no power-off required for installation.

Q: How far can this module transmit?
A: It supports stable 10Gbps transmission up to 20 kilometers over standard OS2 single-mode fiber.
