The Abaco Systems VMIPCI-5588-401 is a high-speed fiber-optic reflective memory PCI card operating at 1.2 Gbaud serial communication rate. This single-slot 5 V PCI card enables deterministic, synchronized data sharing across up to 256 networked nodes by automatically mirroring memory writes across all connected systems. The architecture eliminates processor overhead during network operation, making it ideal for real-time embedded systems demanding low-latency data coherence.
