BlueLAN 40G QSFP+ to QSFP+ Direct Attach Copper Cable, 2m, 28AWG, Passive, 40GbE/56G InfiniBand

The BlueLAN 40G-QSFP-QSFP-P-0501-BL is a high-performance, passive Direct Attach Copper (DAC) cable designed for 40 Gigabit Ethernet and 56 Gigabit InfiniBand (FDR) applications. This BlueOptics Networks compatible cable provides a cost-effective, low-power solution for short-range interconnects in data centers, high-performance computing (HPC) clusters, and enterprise networks.

Advantages

This DAC cable offers significant advantages over active optical cables and transceivers: ultra-low power consumption (<0.5W), no need for external power, and inherent reliability due to passive copper construction. It is hot-swappable and fully compliant with the QSFP+ MSA standard, ensuring seamless integration with BlueLAN and other MSA-compliant equipment. The 28 AWG gauge and 2-meter length provide optimal signal integrity for high-speed data transmission.

Suitable for

• Data center top-of-rack (ToR) to server connections
• High-performance computing (HPC) interconnects
• Enterprise network backbone links
• Storage area network (SAN) connectivity
• Any 40GbE or 56G InfiniBand FDR application requiring short-range copper cabling
