switch.
 There is a changed possibility for supported transceiver module and cable.
10.1.6 SFP+ port
The QX-S5500G Series provide 4 SFP+ ports into a front panel. Also it's possible to mount
SFP+ port of 2 or 8 by loading an expansion interface card into the rear.
You can plug the 1000BASE-X SFP transceiver modules in Table 10-5. You can plug the
10Gbps SFP transceiver modules in Table 10-6. SFP+ cable is inserted in SFP+ port as
need. You can plug the 10Gbps SFP+ transceiver modules in Table 10-7. To expand IRF
fabric, it's possible to use a SFP port as the IRF fabric physical port to connect to switch.
SFP+ cable is indicated on Figure 10-1. An indicated 40G QSFP+/10G*4 SFP+ copper
cable can also be used for Figure 10-3.
