Description
The NI PXIe-8240 is a high-performance 40 Gigabit Ethernet interface designed for seamless integration into PXI systems. With a part number of 784977-01, this unit falls under the category of PXI Interfaces, specifically engineered to cater to demanding network applications and environments.
At its core, the PXIe-8240 employs a robust Intel XL710 40Gb Ethernet Controller, ensuring reliable, high-speed connectivity. The device is equipped with two 40-Gigabit Ethernet QSFP + ports, facilitating efficient and versatile connections to a wide range of network infrastructure including switches, routers, and other 40 Gigabit network devices. Notably, it is compatible with Cisco network equipment, making it a versatile choice for various network setups.
This model is designed as a single slot PXI Express module, ensuring that it easily integrates into existing PXI systems without requiring excessive space. It supports both copper and fiber optic cables, with specific support for QSFP + 40GBase-SR4 fiber optic type. The latter operates at a wavelength of 850nm and is capable of maintaining signal integrity over a maximum distance of 150m, making it suitable for a variety of installation scales and configurations.
Further enhancing its utility, the PXIe-8240 supports hot-plugging, allowing for easy installation or removal without the need to power down the system. It also supports DDM/DOM (Digital Diagnostic Monitoring/Digital Optical Monitoring), enabling real-time monitoring of vital parameters such as temperature, supply voltages, laser bias current, transmit optical power, receive optical power, and transceiver supply voltage.
The PXIe-8240 achieves a maximum data transfer rate of 40Gbps, catering to applications requiring high bandwidth. It is designed for use with multimode (MM) fiber, further broadening its compatibility and application scope. Whether integrating into
