Keep high-speed switch-to-switch or switch-to-server links tight, predictable, and cost-controlled with this 50 cm passive QSFP28 direct attach cable. Built for Aruba Networks compatible 100GBASE-CU deployments, it is designed for short-reach interconnects where optical transceivers would add unnecessary cost and power consumption. The passive copper design is well suited to dense rack environments, top-of-rack architectures, and adjacent equipment connections that demand clean cable management and dependable 100 GbE throughput. Because it is a direct attach assembly, it helps simplify procurement and standardize spares for infrastructure teams that need a practical alternative to optics for in-rack runs. TAA compliance makes it a fit for regulated purchasing environments that require sourcing alignment without compromising on link speed. For teams building repeatable 100 GbE deployments, this cable offers the right balance of reach, simplicity, and acquisition efficiency.
