What type of fiber cable is required for maximum distance?
To reach the maximum supported distance of 2 km, OS2 single-mode fiber is required. If using older OS1 single-mode fiber, the maximum transmission range is limited to 500 meters.
Is the fiber patch cable included with this module?
No, fiber optic patch cables and MPO-12 APC leads are sold separately. Ensure you select compatible Type B APC infrastructure components.
Are these transceivers compatible with older QSFP+ ports?
Yes, the module features backward compatibility design parameters allowing integration with select QSFP+ interfaces on supported UniFi hardware.
What safety precautions should be followed during installation?
This is a Class 1 Laser Product (IEC/EN 60825-1:2014). Never look directly into the open ends of fiber optic cables or active transceiver ports while powered on.
