board will be able to support 8 pairs of 25 Gb/s NRZ modulation or 4 pairs of 50 Gb/s
PAM4 modulation with FPGA's high speed transceivers to achieve 200 Gbps
bandwidth. Furthermore, the QSFP-DD modules also can backward compatible with
QSFP28 and QSFP+ optical transceivers. Figure 2-17 shows the connections
between the QSFP-DD and Agilex FPGA.
