QSFP+ Direct Attach Cables for EX Series Switches

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 34 on page 115.
