Radstone Announces Rear I/O Fibre Channel PMC for Avionics Applications

Radstone Technology, the world's leading independent supplier of high-performance, rugged VME-based computer products, is now shipping the latest addition to its range of Fibre Channel PMC host bus adapters, the PMC FA1R. This conduction-cooled PMC module features Gigabit Fibre Channel rear I/O connection via the backplane, making it especially suitable for installation in ATR chassis for airborne applications. One of the main difficulties faced by a system designer involved in the military or aerospace markets is the restrictive space envelopes imposed by the host environment, which makes rear I/O a preferred option. However, Fibre Channel involves the use of high frequency signals that give rise to signal quality issues if the correct transport media isn't used. Radstone has dealt with these issues.  The PMC FA1R uses active transceivers to equalize the signal and absorb the reflections caused by the non-impedance matched connectors. Radstone has also developed matching processor cards, variants of the PPC4A and PPC4B, that maintain the signal quality to the backplane by impedance matched tracking to P0.  The PPC4B also features 64 bit, 66MHz PCI which maximizes Fibre Channel throughput. The PMC FA1R further extends Radstone's range of Fibre Channel PMC modules that utilize specialized Fibre Channel technology originally deployed by Smith's Electronics Systems - Germantown (formerly Fairchild Defense Division of Orbital Sciences Corporation) for the B-1B stealth bomber program.  This features active transceivertechnology that provides cable equalization and absorbs transmission line effects caused by impedance discontinuities in the transport media.  This allows 1Gigabit transmissions over long lengths of unequalized cables even with non-impedance matched connectors in the path. The PMC FA1R includes software drivers for the VxWorks environment offering SCSI, IP and low latency protocols with connectivity to switched fabric, arbitrated loop and point to point network topologies.  In addition, there is optional support for Delphi Engineering's RDMA protocol, which has been proposed for incorporation into the latest FC-AEP profile. - ends -
