CAUTION:

Minimum bend radius of 40G SFP+ copper cable is 50mm. When not securing minimum bend radius of a
cable, there are damage of a cable and a possibility that performance decrement causes. Don't bend a
cable below the minimum bend radius. Refer to 40G QSFP+ on Figure 10-4 (the right side) for a figure of
the minimum bend radius of 40G QSFP+ copper cable.

10G SFP+ side minimum bend radius of 40G QSFP+/10G*4 SFP+ copper cable is 35mm. 40G SFP+ side
minimum bend radius of 40G QSFP+/10G*4 SFP+ copper cable is 50mm. When not securing minimum
bend radius of a cable, there are damage of a cable and a possibility that performance decrement causes.
Don't bend a cable below the minimum bend radius. Refer to Figure 10-3 for 40G QSFP+/10G*4 SFP+
copper cable. Refer to Figure 10-4 for a figure of the minimum bend radius of 40G QSFP+/10G*4 SFP+
copper cable.

NOTE:

Use SFP transceiver module items of NEC designation for the transceiver module and the cable used for
switch.

There is a changed possibility for supported transceiver module and cable.

It's possible to connect the QSFP+ connector side of the QSFP+/4SFP+ copper cable only at QSFP+ port.
