BlueOptics Atto CBL-0128-003 Compatible Direct Attach Copper Cable (DAC) Passive 40Gbps QSFP+ to QSFP+ 1m

The BlueOptics Atto CBL-0128-003 compatible Direct Attach Copper (DAC) cable is a high-performance, passive twinaxial cable designed for 40 Gigabit Ethernet and InfiniBand QDR/FDR applications. It provides a reliable, low-latency connection for data center interconnects, rack-to-rack, and server-to-switch links. With QSFP+ connectors on both ends, this cable is hot-pluggable and compliant with SFF-8436 MSA standards, ensuring seamless integration with compatible hardware.

Advantages

This passive DAC cable offers a cost-effective and energy-efficient solution for short-range high-speed connections. Its twinaxial construction minimizes signal loss and crosstalk, while the 100 Ohm impedance ensures optimal performance. The cable is lightweight and flexible, simplifying cable management in dense rack environments.
