National Instruments QSFP28 Twinaxial Cable
The National Instruments QSFP28 (part number 788215-03) is a passive direct attach copper (DAC) QSFP28 cable that has been developed as a high-performance 100G QSFP28 cable intended for applications that require high performance in testing and measurement. This 3m DAC cable is a fully integrated cable solution that includes QSFP28 connectors at each end to provide a low-latency, reliable data transfer path. The primary purpose of the cable is to support high-speed data transfer for those applications with high signal quality and synchronization requirements, such as many R&D applications.
This cable was created for National Instruments USRP (Universal Software Radio Peripheral) platforms and additional high-speed devices in mind. The most popular applications for this cable include large MIMO system topologies, wireless communication prototyping, and SDR prototyping. Additionally, the cable's twinaxial architecture offers exceptional stability and EMI immunity for all kinds of applications, which are crucial for achieving precise and consistent outcomes in signal processing and data collecting applications. For real-time analysis and high-throughput operations, engineers rely on this DAC cable to establish a continuous and error-free data transfer connection between processing units and radio heads.
The National Instruments 788215-03 cable provides a dedicated 100 Gigabit Ethernet connection and therefore reduces the number of components required for the system and reduces the number of possible points of failure for the system. The cable is built to endure the demands of industrial automation applications and automated test systems, and it will function reliably in both production and laboratory settings. As a result, this cable is an important part of any high-performance NI ecosystem and is the foundation of the high-speed data backbone for many cutting-edge projects, including 5G research, spectrum monitoring, and aerospace and defense applications.
