100G QSFP28 to QSFP28 Direct Attach Copper Cable (DAC), Passive, up to 5 m (16 ft)
Overview
The NS 100G QSFP28 to QSFP28 Direct Attach Copper Cable (DAC) is a high-performance, cost-optimized solution for 100 Gigabit Ethernet short-reach interconnects. Designed with twinax copper cable and integrated QSFP28 connectors, it eliminates the need for optical transceivers and patch cords, offering a plug-and-play, low-latency alternative.
The passive version supports distances up to 5 m (16 ft), delivering ultra-low latency and zero power consumption. For extended connectivity, active copper DACs can reach up to 7 m (23 ft) with minimal power usage (< 1.5 W). This makes the cable ideal for top-of-rack (ToR) and middle-of-row (MoR) server-to-switch or switch-to-switch deployments.
Compatible Brands
The NS 100G QSFP28 DAC is tested for compatibility with Cisco, Huawei, Juniper, Arista, Dell, Netgear, Intel, HPE Aruba, Fortinet, and other leading platforms.
