2.5 QSFP28 Ports
The Carrier board has two independent 40G QSFP28 connectors that use one transceiver channel
each from the Stratix 10 FPGA device. These modules take in serial data from the Stratix 10 FPGA
device and transform them to optical signals. The board includes cage assemblies for the QSFP28
connectors. Figure 2-9 shows the connections between the QSFP28 and Stratix 10 FPGA.
