The Curtiss-Wright FX400 is a dual-channel Fibre Channel host bus adapter in PMC form factor, delivering two independent 4.25 Gbps FC interfaces with combined full-duplex throughput of 1600 MBps. The card integrates advanced I/O processing and multi-protocol support into a single slot, eliminating the need for multiple separate adapters. Auto-speed negotiation supports 1.0625 Gbps, 2.125 Gbps, and 4.25 Gbps operation for transparent compatibility with existing infrastructure. Twin RISC I/O engines minimize host CPU overhead while handling SCSI Fibre Channel Protocol (FCP), Internet Protocol (IP), File System SCSI, and Raw Initiator SCSI simultaneously. Hot-swappable SFP transceiver modules enable flexible media interface configuration. Available in air-cooled and conduction-cooled variants, the FX400 integrates into PCI, VME, and Compact PCI-based embedded systems for military, aerospace, and rugged industrial applications.
