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.
