The cables are hot-removable and hot-insertable. A cable consists of a cable assembly
that connects directly into two SFP+ modules, one at each end of the cable. The cables
use integrated duplex serial data links for bidirectional communication and are designed
for data rates up to 10 Gbps. There are two types of DAC cables:
Passive DAC cables have no signal amplification built into the cable assembly. The
