SFP+ Modules
The development board include two SFP+ modules that use transceiver channels
from the FPGA. These modules takes in serial data from the FPGA and transform
them into optical signals. Both SFP+ ports are active and include the SFP+ cage
assembly only when the Arria V GT FPGA device is installed.
1 The Arria V GX FPGA development board includes only one SFP+ cage assembly for
the SFP+ port used by the device.
Table 2–28 list the SFP+ modules interface pin assignments, signal names, and
functions.
