BlueLAN 00KF006-BL Compatible Lenovo Mellanox QSFP+ Direct Attach Cable, 40GBASE-CR4, 0.5m, Passive Copper Twinax, Ethernet/InfiniBand

Data center technicians and network engineers use the BlueLAN 00KF006-BL to link QSFP+ ports on Lenovo and Mellanox switches, servers, and storage systems over short distances. This passive copper twinax cable delivers 40 Gbps throughput with minimal power draw, making it a practical choice for high-density racks and HPC clusters.

Key specifications

• Connector: QSFP+ (SFF-8436 MSA compliant)
• Cable length: 0.5 m (1.64 ft)
• Data rate: 40 Gbps (40GBASE-CR4)
• Protocol support: Ethernet, InfiniBand
• Cable type: Passive copper twinax, 30 AWG, 100 Ohm impedance
• Operating temperature: 0°C to 70°C
• Hot-pluggable: Yes

Why choose it

Passive construction means no signal processing, so the cable consumes under 0.1 W per end and adds no latency. PVC jacketing keeps it flexible for tight cable management, and the QSFP+ connectors lock securely to prevent accidental disconnects.

Ideal use cases

• Connecting top-of-rack switches to servers in data centers
• Linking storage controllers in high-performance computing environments
• Short-reach InfiniBand fabric connections

Good to know

This cable is compatible with Mellanox 00KF006 and equivalent Lenovo part numbers. It is RoHS compliant and built to MSA standards, ensuring reliable interoperability with compliant QSFP+ ports.
