connected to the EU and a maximum of five RUs can cascade when RU1 is directly connected to the AU. (See Figure 10- 4)
The maximum bandwidth per operating band should be less than 60MHz and the maximum bandwidth of all operators
should be less than 200 MHz.

CrossFire provides a transparent pipeline for 10M/100M/1000Mbps Ethernet transmission. Each EU has six electrical
ports (GE1~GE6) for six WLAN signals to access. Meanwhile, six optical ports (OP1~OP6) correspond to GE1~GE6 for the
output signal. (See Figure 10- 5) The flow path of the signal is:
Input LAN signals— EU— RU— AP— POI— Antenna-feeder system.
Note:
•
The electrical port must correspond to an optical port, for example, GE1 corresponds to OP1.
•
If multiple cascading RUs connect, the WLAN signal can be output from a random RU.
•
If multiple cascading RUs connect and more than one AP device connects to the RUs, the WLAN
signal can be output from one RU, and the priority is RU1
＞
RU2
＞
RU3.
