Turn a single 40 GbE uplink into four 10 GbE connections with a passive QSFP+ to 4x SFP+ breakout DAC built for short-reach data center use. The 2 m length is a practical fit for adjacent equipment, allowing teams to distribute bandwidth where it is needed without adding optical modules or extra patching complexity. This cable is a strong choice for network teams standardizing on mixed-speed infrastructure. It supports efficient fan-out from a QSFP+ port to multiple SFP+ endpoints, making it useful for aggregation, migration, and rack-level distribution scenarios. The passive copper design keeps the assembly simple and helps reduce power consumption compared with active alternatives. For procurement, the appeal is clear: one cable can replace multiple discrete interconnects in the right topology. For operations, the benefit is equally direct: predictable short-run connectivity, fewer components to manage, and a cleaner path through high-density racks. In environments where every port and every inch of rack space matters, this breakout DAC delivers practical density without unnecessary overhead.
