Lightwin 100G QSFP28 to QSFP28 Direct Attach Copper Cable, 3m, HPE Aruba Compatible LWO-DAC-QSFP28-3M-HPE

High-speed 100 Gigabit Ethernet interconnect cable with QSFP28 connectors on both ends, engineered for seamless compatibility with HPE Aruba networking equipment. This passive direct attach copper (DAC) cable delivers reliable 100Gbps data transfer over a 3-meter reach, making it ideal for top-of-rack switching and short-distance server connections.

Advantages

Passive DAC design consumes less than 0.1W, reducing power and cooling costs compared to optical transceivers. Hot-pluggable connectors allow quick installation without network downtime. Factory-coded for HPE Aruba switches, routers, and servers, ensuring plug-and-play operation. Robust PVC jacket and 26 AWG copper conductors provide excellent signal integrity and durability.

Suitable for

• 100GBASE-CR4 Ethernet links in data centers and enterprise networks
• Connecting HPE Aruba switches to servers, storage, or other switches within a rack
• High-performance computing clusters and low-latency trading environments
• Replacing optical transceivers for cost-effective short-range 100G interconnects
