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.

10.5. WLAN Application
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 RU1RU2RU3.
