40G QSFP+ passive direct attach copper cable for short-haul data center connections.
When high-speed interconnect costs strain data center budgets, passive cabling offers essential savings without sacrificing performance. This QSFP+ direct attach cable solves short-reach connectivity challenges between adjacent racks where expensive optical modules are unnecessary.
Supporting 40 Gb/s bi-directional data links, this passive DAC eliminates active component power draw with less than 0.1W consumption, reducing cooling overhead. Fully compliant with IEEE802.3ba and Infiniband QDR specifications, it ensures reliable interoperability while increasing port density for 40G Ethernet applications.
Ideal for serial data transmission and cabinet-to-cabinet links, the all-metal housing delivers superior EMI performance compared to standard copper alternatives. The LRDAC-QSFP+-1M compatible QSFP+-DAC-3m provides enterprise-grade reliability at a fraction of optical transceiver costs.
Supports up to 40 Gb/s bi-directional data links for high-bandwidth data center applications.
Passive design consumes less than 0.1 watts, significantly reducing power and cooling costs.
Fully compliant with IEEE802.3ba and Infiniband QDR specifications for guaranteed interoperability.
All-metal housing provides superior EMI performance for reliable signal integrity in dense environments.
Preferred low-cost solution for short-haul 40G Ethernet connections between adjacent cabinets.
High-quality optical modules and cables for optimal compatibility with your network adapter.
