Connector system for high-speed interconnect

8 March 2006 Interconnection

The AirMax VS connector system from FCI is a comprehensive family of high-speed, lightweight, flexible, and scaleable connectors that suits a broad range of applications in data, communications, and industrial equipment.

The innovative system uses edge-coupling technology and an air dielectric between adjacent conductors to deliver high signal density with low insertion loss and low crosstalk, and it does this without the use of costly and space-consuming metal shields. According to the manufacturer, data rates can scale from 2,5 Gbps to beyond 12 Gbps without requiring redesign of a basic platform.

Co-planar signal, power, and guidance modules from the AirMax VS family are well-suited for use as Zone 3 interconnects in next-generation AdvancedTCA carrier-grade communications equipment. Zone 3 in an AdvancedTCA shelf allows for direct connection between an AdvancedTCA front board and a rear transition module (RTM) to route signals to the rear of an AdvancedTCA rack. AirMax VS right-angle signal modules easily enable these high-density connections. Up to four 150-position modules, each module supporting 50 differential pairs, can be placed side by side in Zone 3 to provide a total of 200 differential pairs.

In addition to superior electrical performance, they offer design versatility because signal connectors can be scaled by varying the number of columns of contacts, the number of contacts per column, and the column spacing. AirMax VS connectors also allow for mixed-pin assignments (differential or single-ended signals or power), to provide additional flexibility for system designers.

Co-planar power modules are also available to provide increased current-carrying capacity when needed. These are compact 12 mm-wide modules that use a 1 x 2 or 2 x 2 contact configuration rated to 80 A with 150 V voltage rating. Two available mating lengths for power receptacle contacts offer capability for sequential mating of power, ground, and signal contacts.

More information on the connector system can be seen at www.fciconnect.com/airmax.
