Cabo de cobre de ligação direta Lightwin 100G QSFP28 para QSFP28, 1m, compatível com HPE Aruba (LWO-DAC-QSFP28-1M-HPE)

High-performance 100 Gigabit Ethernet connectivity in a compact, energy-efficient form factor. This Lightwin Direct Attach Copper (DAC) cable delivers a full 100 Gbps link between QSFP28 ports over a 1-meter passive twinax assembly, ideal for short-reach interconnects in modern data centers and enterprise networks. Fully compatible with HPE Aruba networking equipment, it provides a reliable, low-latency alternative to optical transceivers for top-of-rack and adjacent-rack deployments.

Advantages

Passive twinax design consumes virtually no power, reducing operational costs and heat output compared to active optical cables. Hot-swappable connectors allow for quick installation and maintenance without disrupting network operation. The robust copper construction ensures signal integrity and durability, while compliance with SFF-8665 QSFP28 MSA guarantees interoperability with a wide range of switches, routers, and servers. Operating temperature range of 0°C to 70°C supports deployment in standard data center environments.
