Airmax VS® Orthogonal

To further expand the range of applications supported by the AirMax VS® connector system, AFCI has added a 4-Pair by 4-Pair Orthogonal connector solution. The connectors enable the efficient implementation of orthogonal midplane architecture, where vertical add-in cards on one side of a midplane are connected to horizontal add-in cards on the opposite side of the midplane. The AirMax VS® Orthogonal midplane interface features two back-to-back AirMax VS® headers oriented at 90 degrees to each other. The headers connect 16 differential signal pairs through shared vias in the midplane, providing a direct, high-speed connection while eliminating traces on the midplane. The AirMax VS® Orthogonal midplane interconnects can support differential signaling at up to 20Gb/s. System architects may now customize and assign their highestspeed signals to the orthogonal pins while routing other signals through the standard AirMax VS® backplane connectors. This additional capability offers yet another level of increased system design flexibility.

Since AFCI first introduced the AirMax VS® connector system in 2003, AFCI has continually added products and product extensions to the AirMax VS® family:

• Vertical receptacle and right angle header

• Vertical header and right angle receptacle

• Co-planar connectors

• Mezzanine connectors

• Power connectors

• Guide pins and guide blades

The AirMax VS® connector family has given system architects outstanding design flexibility at a low cost with proven signal speed performance to beyond 12.5Gb/s.
