BlueOptics Compatible Maipu QSFP-STACK-20 BlueLAN QSFP Direct Attach Cable, 40GBASE-CR4, Ethernet/Infiniband QDR, 30AWG, 2 Meter (QSFP-STACK-20-BL)

The BlueOptics QSFP-STACK-20-BL is a high-performance, passive Direct Attach Cable (DAC) designed for 40 Gigabit Ethernet and InfiniBand QDR applications. This 2-meter twinax copper cable features QSFP connectors on both ends, providing a cost-effective and low-power solution for short-range interconnects in data centers and high-performance computing environments. Fully compatible with Maipu QSFP-STACK-20 and other standard QSFP 40G ports, it ensures reliable, high-speed data transmission with minimal latency.

Advantages

This DAC cable offers significant advantages over active optical cables and transceivers: lower power consumption (<0.5W), reduced cost, and simplified cable management. The 30 AWG gauge ensures flexibility while maintaining signal integrity over the 2-meter length. Hot-swappable design allows for easy installation and maintenance without network downtime.

Suitable for

• Data center top-of-rack to server interconnects
• High-performance computing clusters
• Enterprise network aggregation and core switching
• InfiniBand QDR fabric connections
