40G QSFP+ passive DAC cable for short-haul data center interconnects.
When high-speed interconnect costs escalate in dense server racks, passive cabling offers a reliable alternative to optical modules. The LRDAC-QSFP+-5M QSFP+ direct attach cable addresses this by providing stable 40G connectivity for adjacent cabinet links without active component overhead.
Supporting up to 40 Gb/s bi-directional data links, this passive DAC eliminates signal conversion latency while consuming less than 0.1 watts of power. Its compliance with IEEE 802.3ba ensures seamless integration into existing Ethernet fabrics, enabling significant energy savings across large-scale deployments compared to active optical solutions.
Designed for data center and cabinet-to-cabinet transmission, the cable’s all-metal housing delivers superior EMI shielding for signal integrity. This 5-meter solution provides a low-cost, high-reliability connection point for 40G Ethernet applications requiring robust physical layer performance.
Supports up to 40 Gb/s bi-directional data links compliant with IEEE 802.3ba.
Passive design consumes less than 0.1 watts, reducing data center energy costs.
All-metal housing ensures signal integrity in high-density rack environments.
Preferred 5m passive cable for cost-effective intra-rack and adjacent cabinet connections.
High-quality optical modules and cables for optimal compatibility with your network adapter.
