4 slot 100Gb SOSA Aligned 3U VPX System Development

Designed to address lower slot count system development, the DK3HS-4 is a lighter weight option for smaller system integration efforts. It supports 25Gb per lane data rates for 100Gb performance in new systems being developed for VPX, OpenVPX 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.

LCR VPX development systems support MOSA (modular open
systems approach) by enabling electronics design based on VPX, OpenVPX, and
SOSA-aligned architectures for defense applications.

LCR DK3HS4 Development System

DK3HS-4 includes power and ground backplane, power supply, fan cooling and rear transition area. Backplane profiles are created using slot to slot cabling systems.
