BlueLAN QSFP-40G-2M-CM-BL Compatible H3C QSFP+ Direct Attach Cable, 40GBASE-CR4, 30AWG, 2 Meter

The BlueLAN QSFP-40G-2M-CM-BL is a high-performance, passive copper twinax direct attach cable (DAC) designed for 40 Gigabit Ethernet and InfiniBand QDR applications. It is fully compatible with H3C switches and routers, as well as any MSA-compliant QSFP+ port. This 2-meter cable provides a cost-effective, low-power solution for short-range interconnects in data centers and high-performance computing environments.

Advantages

This direct attach cable eliminates the need for separate transceivers and fiber optic cabling, reducing cost and complexity. With a power consumption of less than 0.5W, it is highly energy-efficient. The 30 AWG construction ensures flexibility while maintaining signal integrity over the 2-meter length. Hot-swappable design allows for easy installation and maintenance without disrupting network operations.

Suitable for

• Data center top-of-rack to server or switch interconnects
• High-performance computing (HPC) clusters
• 40GBASE-CR4 Ethernet and InfiniBand QDR networks
