BlueOptics Atto CBL-0130-001 Compatible 40G QSFP+ Passive Direct Attach Copper Cable 1m

The BlueOptics Atto CBL-0130-001 compatible Direct Attach Cable (DAC) is a high-performance passive 40 Gigabit Twinaxial Copper solution designed for reliable connectivity within racks and across adjacent racks. Featuring QSFP+ connectors on both ends, this cable delivers 40 Gbps data rates with ultra-low power consumption, making it an ideal choice for data center interconnects, server-to-switch links, and high-speed networking environments.

Advantages

This passive DAC cable offers a cost-effective and energy-efficient alternative to active optical cables or transceivers. With zero power consumption (less than 0.1W), it reduces overall system power draw and heat generation. The twinaxial copper construction ensures low latency and high signal integrity over short distances, while the hot-swappable QSFP+ connectors enable easy installation and maintenance without network downtime.

Suitable for

• Data center rack-to-rack and rack-to-switch connections
• Server-to-switch and switch-to-switch links in 40G networks
• High-performance computing (HPC) clusters
• Storage area networks (SAN) requiring low-latency copper interconnects
