A fiber network is classified into a ring network and a star network, as shown in
and
In the fiber networking, the SmartLogger connects to an inverter over an RS485
communications cable or an AC power cable, connects to a box-type transformer over an
RS485 communications cable or an Ethernet network cable, and connects to southbound
devices such as the EMI and power meter over RS485 communications cables.

The SmartLogger can work with the SUN2000 equipped with the PLC STA module over an embedded
or external PLC CCO module to implement PLC networking over power cables.
 The SmartLogger provides two 100M Ethernet optical ports to implement ring networking.
 A maximum of 16 SmartLoggers can be connected to form a fiber ring network. Each SmartLogger
can connect to southbound devices such as the inverter, EMI, and power meter.
 Multiple fiber ring networks can converge over an Ethernet switch or SmartLogger and then connect
to an NMS.
