10. SFP Module Connector
The board contains a small form-factor pluggable (SFP) connector and cage assembly that
accepts SFP modules. The SFP interface is connected to MGT Bank 116 on the FPGA. The
SFP module serial ID interface is connected to the "SFP" IIC bus (see “15. IIC Bus,” page 42
for more information). The control and status signals for the SFP module are connected to
jumpers and test points as described in Table 1-9. The SFP module connections are shown
in Table 1-10, page 36.
