Twisted-Pair Interface
The copper port provides a shielded RJ-45 connector that supports a
maximum segment length of 100 meters. Use only Category 5 cables.
Fiber Optic Interface
The unit’s fiber receiver (RX) is to the right of the transmitter (TX).
When making network connections, make sure that the fiber receiver
on the Access ONU connects to the transmit port of the connected
device, and that the receive port of the connected device connects to the
Access ONU’s fiber transmitter.
The fiber optic multimode interface supports a maximum segment
length of 2km.
The singlemode (SM) connector supports a maximum segment length
of 20km, 40km, or 100km, depending on the model.
To enable remote management, make sure the management (MAN)
LED is ON after connecting the fiber cable to the Access ONU. If the
MAN LED is not lit, reset the unit or the Access Line Card it is
connected to by using software commands or a complete power cycle.
