BLUEOPTICS Compatible Cisco QSFP-H40G-CU0.5M BlueLAN QSFP Direct Attach Cable, 40GBASE-CR4, Ethernet/Infiniband QDR, 30AWG, 0.5 Meter (QSFP-H40G-CU0.5M-BL)

The BLUEOPTICS QSFP-H40G-CU0.5M-BL is a high-performance, cost-effective direct attach copper (DAC) cable designed for 40 Gigabit Ethernet and InfiniBand QDR applications. This passive twinax cable assembly provides a reliable, low-latency interconnect solution for data centers and high-performance computing environments. Fully compatible with Cisco QSFP-H40G-CU0.5M equipment, it ensures seamless integration into existing networks.

Advantages

This DAC cable offers significant advantages over traditional fiber optic transceivers: lower power consumption (less than 0.5W per end), reduced cost, and simplified cable management. The 30AWG construction ensures flexibility while maintaining signal integrity over the 0.5-meter length. Hot-pluggable QSFP+ connectors allow for easy installation and replacement without powering down equipment.
