Detailed Description
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 123 on the FPGA. The
SFP module serial ID interface is connected to the “SFP” IIC bus (see
information). The control and status signals for the SFP module are connected to jumpers
and test points as described in
. The SFP module connections are shown in
Table 1-12:
