Reference Manual

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.
