6.7.6. SFP+

The Arria® 10 GX FPGA development board includes one SFP+ module that uses transceiver channels from the FPGA. This module takes in serial data from the FPGA and transform them into optical signals. The Arria® 10 GX FPGA development board includes one SFP+ cage assembly for the SFP+ port that is used by the device.
