Alcatel-Lucent QSFP+ naar QSFP+ Direct Attach koperkabel, 3 m, 40GbE, passief, zwart

Direct Attach Copper (DAC) cable engineered for 40 Gigabit Ethernet, linking QSFP+ ports across short distances with zero optical transceivers. This 3-meter passive copper assembly delivers 40GBASE-CR4 performance at minimal power draw, making it a practical choice for dense data center racks and high-performance computing clusters.

Advantages

Passive DAC design consumes virtually no power, reducing both energy costs and heat output inside the rack. The 26 AWG copper conductors and PVC jacket provide a robust yet flexible link that withstands frequent re-cabling. Hot-pluggable QSFP+ connectors allow live insertion and removal without interrupting adjacent ports, while full IEEE 802.3ba compliance ensures interoperability with Alcatel-Lucent and Nokia switches and routers.

Suitable for

• Top-of-rack to end-of-row server connections in enterprise data centers
• High-performance computing (HPC) clusters requiring low latency and high bandwidth
• Storage area networks and converged infrastructure using 40GbE uplinks
• Short-reach interconnects between QSFP+ switches, routers, and network appliances
