The NI 781042-100 is a 100 meter MXI-Express Gen 1 x4 fiber optic cable engineered for high-speed PCIe communication between host computers and remote PXI Express chassis. This cable enables extended-reach connectivity with electrical isolation, supporting data transfer rates up to 832 MB/s sustained throughput over the x4 lane configuration. Fiber optic technology delivers reliable signal integrity across distances where copper interconnects degrade performance.

– Key Features
• Electrical isolation between host PC and PXI chassis eliminates ground loop issues and protects sensitive instrumentation.
• Extended reach capability supports distributed test and control architectures without signal regeneration or intermediate equipment.
• Direct point-to-point connectivity between PCIe-8375 controllers and PXIe-8375 chassis or between two PXIe-8375 units.
• Supports both single-chassis and multi-chassis configurations including star and daisy-chain topologies.
– Typical Applications
• Remote control of PXI and PXI Express modular instrument chassis from host servers.
• Multi-chassis instrument synchronization with extended geographical separation.
• High-speed data streaming between distributed test benches and control computers.
• Systems requiring galvanic isolation between PC and instrumentation hardware.
– Compatibility & Integration
The cable connects PCIe x4 slots in host computers to PXI Express or CompactPCI Express chassis compliant with PCI Express Specification Revision 1.0a or later and PXI Express Hardware Specification Revision 1.0 or later. Configuration flexibility accommodates single controller to single chassis links as well as multi-chassis hierarchies with daisy-chaining or star network topologies.
