Why choose it

Passive DAC cables offer the lowest latency and power consumption for short-reach 100G interconnects. With a 30 AWG wire gauge, this cable is thin and flexible, simplifying cable management in dense racks. It is fully compatible with HPE R1N34A and other QSFP28 ports that support passive copper per SFF-8665.

Ideal use cases

• Server to top-of-rack switch connections within the same rack
• High-performance computing (HPC) clusters using InfiniBand EDR
• Enterprise data center leaf-spine architectures
• Storage area networks requiring 100G Ethernet

Good to know

This cable is hot-swappable and requires no additional power. Its passive design means no signal regeneration, so it is best suited for distances up to 5 meters. The PVC jacket provides durability while maintaining flexibility.
