Fabric40 OpenVPX Signal Integrity: Gen3 OpenVPX Backplanes Supporting 10.3 Gbaud Signaling in OpenVPX Systems White Paper

The OpenVPX (VITA 65) ecosystem transitioned from Gen2 to Gen3 signaling, which brings with it an increase in signaling rates from 6.25 Gbaud to >10 Gbaud. The near doubling of bandwidth resulting from this change brings with it significant design challenges as the MultiGig connector used with OpenVPX approaches its performance limits. Curtiss-Wright Defense Solutions has done extensive research to develop highly optimized 10G compliant design techniques for attaining reliable and robust signal integrity performance with Gen3 OpenVPX systems; our Fabric40 family of products is designed to address these design challenges.
