Pixus Technologies has developed a high performance OpenVPX backplane with signals above 28 Gbaud across the backplane slots. 

The design leverages the 6U OpenVPX form factor and VITA 66/67 RF and optical interfaces with its  special high-speed connector, previously used in high speed backplanes, for the fastest data rates.

 The backplane features 14 slots with both RF and optical interfaces through the backplane to the rear panel of a Pixus RiCool chassis. 

The design uses high-grade PCB materials, back-drilling, and specialized routing strategies to optimize signal performance.  For speeds of PCIe Gen4 (16 Gbaud/sec) or above, the company typically performs signal integrity (SI) studies to help ensure the performance of the high-speed signals.  The SI results of these backplanes have shown excellent results with large eye diagram openings.

Pixus offers SOSA-aligned, OpenVPX, and other modular open standard architecture backplane/enclosure solutions.  The company also offers various specialty boards in various standards, including power interface boards, alarm cards, chassis managers, and more.
