Connector modules simplify
routing in ATCA racks
AirMax VS coplanar signal, power and guidance modules are ideally suited for use as Zone 3 interconnects in next-generation AdvancedTCA carrier-grade communications equipment
FCI has demonstrated that its AirMax VS coplanar signal, power and guidance modules are ideally suited for use as Zone 3 interconnects in next-generation AdvancedTCA carrier-grade communications equipment. Zone 3 in an ATCA shelf allows for direct connection between an ATCA front board and a rear transition module (RTM) to route signals to the rear of an ATCA rack.

Connectors support next-generation backplanes
Huawei and FCI have successfully demonstrated 12.5Gbit/s transmission on a backplane system designed around the ATCA building practice using FCI's AirMax VS connectors in Zone 2
Backplane connectors boast more options
The AirMax VS backplane connector system is billed as the broadest line of high-speed backplane connectors available
AirMax VS right-angle signal modules easily enable these high-density connections because up to four 150-position modules, each supporting 50 differential pairs, can be placed side by side in Zone 3 to provide a total of 200 differential pairs.
Having seen the benefits of AirMax VS when used in Zone 3, OEMs are now designing systems that also use the connectors in Zone 2.
Backplane suppliers, like Sanmina-SCI and Interconnect Technologies, are supporting the use of AirMax VS connectors in custom ATCA backplanes because of cost and performance advantages.
Recently, Huawei and FCI, supported by Sanmina-SCI, successfully demonstrated 12.5Gbit/s differential signal transmission on a backplane system designed around the ATCA building practice using AirMax VS connectors in Zone 2.
The demonstration proved that custom ATCA backplanes allow for performance levels beyond what ATCA was originally designed to provide.

Novel backplane connector gains second source
FCI has signed a second source licence agreement granting Amphenol the right to manufacture, market, and sell the four- and five-pair AirMax VS (Virtual Shield) connector worldwide
The very low crosstalk of less than 1% exceeded the expectations of both Huawei and FCI design engineers.
The flexibility of the AirMax VS system provides options to increase pin density within a slot as much as 20% bandwidth as a standard ATCA backplane.
The AirMax VS connector system provides the most comprehensive family of high-speed, lightweight, flexible and scaleable connectors available today, making it ideal for a broad range of applications in data, communications, and industrial equipment.
The revolutionary system uses edge-coupling technology and an air dielectric between adjacent conductors to deliver high signal density with low insertion loss and low crosstalk, all without the use of costly and space-consuming metal shields.
datarates can scale from 2.5 to beyond 12Gbit/s without requiring redesign of a basic platform.
In addition to superior electrical performance, the AirMax VS family offers 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 to system designers.
Another benefit of the AirMax VS system its dual beam contact system, with opposing beams that greatly improve the reliability of the interconnect.
AirMax VS power modules are also available to provide increased current-carrying capacity when needed, in right-angle and co-planar applications.
These compact 12mm-wide modules use a 2 x 2 contact configuration rated to 80A with 150V voltage rating.
Two available mating lengths for power receptacle contacts provide capability for sequential mating of power, ground and signal contacts.
