4.2 SFP+ Connector

The development board has four independent 10G SFP+ connectors that use one transceiver channel each from the Arria 10 SoC FPGA device. These modules take in serial data from the Arria 10 SoC FPGA device and transform them to optical signals. The board includes cage assemblies for the SFP+ connectors.Figure 4-3 shows the connections between the SFP+ and Arria 10 SoC FPGA.

Figure 4-3 Connection between the SFP+ and Arria 10 SoC FPGA

Table 4-3, Table 4-4, Table 4-5 and Table 4-6 list the four QSF+ connectors assignments and signal names relative to the Arria 10 SoC FPGA
