The XFP/SFP+ Tab
The XFP/SFP+ tab allows you to run an XFP or SFP optical loopback test. You can also
run the test using an electrical loopback test if you do not have an SFP or XFP module
with optical loopback fibre available.

To test the board using an XFP optical module from the BTS, if the optical module
requires a divide by 64 REFCLK, perform the following steps before powering on the
board:
1. Set SW6[1] (8:1) to SMA, and SW6[2] (7:2) to OSC.
2. Connect differential clock cables from SMAs J72/73 to J79/J80.
Figure 6–5 shows the XFP/SFP+ tab.
The following sections describe the controls on the XFP/SFP+ tab.
