Quad small form-factor pluggable plus (QSFP+) direct attach copper cables are suitable
for in-rack connections between QSFP+ ports of EX Series switches. They are suitable
for short distances of up to 16.4 ft (5 m), making them ideal for highly cost-effective
networking connectivity within a rack and between adjacent racks. See
Figure 40 on page 133.
