High speed VPX systems incorporating PCIe Gen 4 / Gen 5 and 100GBASE-KR4 protocols are here. The DK3HS supports 25Gb per lane data rates for 100Gb performance in new systems being developed for VPX and SOSA aligned payloads. It enables the early stages of system development with open access and flexible configurability resulting in faster time to deployment for critical mission requirements in new and emerging defense programs. DK3HS includes power and ground backplane, power supply, fan cooling and rear transition area. Backplane profiles are created using slot to slot cabling systems.
