Caution:
10G SFP+ side minimum bend radius of 40G QSFP+/10G SFP+ Copper cable is 35mm.
40G QSFP+ side minimum bend radius is 50mm. When not securing minimum bend radius
of a cable, there is damage of a cable or a possibility that performance deterioration forms.
Don't bend a cable below the minimum bend radius.

QX-S6600 Series provide QSFP+ ports. You can plug the QSFP+ transceiver modules in
Table 10-8 and the QSFP+ cables in Table 10-9 into the SFP+ ports as needed.
The QSFP+ cables available for the QX-S6600 Series are 40 Gbps SFP+ Copper cables,
as shown in Figure 10-5. The SFP+ cables available for the QX-S6600 Series are 40G
QSFP+/10G*4 SFP Copper cables, as shown in Figure 10-3.
