Network Applications
The ZXRAN V9200 supports the star or chain networks with RRUs through optical fibers.
Star network: Each RRU is connected to the ZXRAN V9200 in point-to-point mode. This networking mode has higher reliability, but requires more transmission resources. It is applicable to more densely populated areas.

Network Applications
Chain network: Multiple RRUs are connected into a chain, and then connected to the ZXRAN V9200. This mode requires fewer transmission resources, but has less reliability.
