As an extension of VITA 65 OpenVPX, VITA 66 enables a compatible VPX interface containing blind mate optical connectors with fixed contacts on the Plug-In Module and floating displacement on the backplane.

vita standards organization

VITA 66 allows for improved and diversified I/O density via fiber transceivers and cables. While transceivers can be dense and perform at a high speed, they often consume valuable board real-estate, require additional hardware, and are difficult to integrate due to an ultra-fine pitch.

Samtec compliments the VITA 66 standard by offering our cabled FireFly™ Micro Flyover System™. FireFly™ supports SWaP-C and offers more density and performance (28+ Gb/s) than optical transceivers while consuming less board space.

Samtec's FireFly™ interconnect system gives designers a choice of using either low-cost copper cables or high performance active optical engines to meet today's data rate requirements and the next generation. The flexible design of FireFly™ allows it to act as a suitable compliment to the VITA 66 Standard above the optical transceiver.

The Expanding Optical VPX Ecosystem

The Expanding Optical VPX Ecosystem

As 1-inch slot pitch OpenVPX systems continue to gain popularity among system designers, optical I/O has had to adapt both its size and capacity for additional cabling. VITA 66 acts as a next step in this process allowing for up to 3x cabled transceiver interfaces.

Abaco VP868 VPX FPGA Card

The Abaco VP868 6U FPGA Card is a high performance 6U VPX plug-in module with advanced digital signal processing capabilities. At the heart of the VP868 is a Zynq dual ARM-9 device for processing offload and board management.

The module is ideal for applications requiring both high performance processing and I/O with the ability to scale from the lab to deployed rugged environments. It supports a VPX RTM designed to connect high-speed SERDES channels from the payload module to Samtec FireFly™ optical engines. Each optical engine routes 12 RX channels and 12 TX channels to industry-standard MTP connectors in a rear bezel.

Pentek Flexor 5973

The Pentek Flexor 5973 incorporates the VITA 66.4 optical interconnect standard for OpenVPX, which delivers 12 optical duplex lanes to a backplane, or for other board-to board, high-data-rate connections. The board employs one 12-channel FireFly™ Tx module and one 12 channel FireFly™ Rx module. The optical fibers from these modules route over the top of the board and join at the board's MT ferrule at the VPX P2 location. Each optical FireFly™ channel operates at data rates to 14 Gbps for an aggregate system data rate of 336 Gbps through the optical interconnect.
