Keep high-speed links tight, direct, and predictable with this 100G-CR4 QSFP28 DAC from UNC Group. Built for Arista-compatible environments, the 2 m passive copper assembly is designed for short-reach interconnects between switches, servers, and storage nodes where optical transceivers would add cost and unnecessary complexity. For data center teams, DAC is often the cleanest answer when equipment sits in the same rack or directly adjacent racks. This cable supports 100G connectivity without the added power draw, heat, or transceiver management overhead of optics. That makes it a practical choice for dense deployments that need to preserve airflow, reduce component count, and keep link budgets simple. The 2 m length gives you enough reach for structured rack layouts while staying short enough to maintain a tidy cable path. For procurement teams, it offers a straightforward way to standardize short-run 100G links with a compatible form factor that fits enterprise switching environments. When the requirement is fast, direct, and cost-conscious at scale, this DAC is built for the job.
