**BACKPLANE CONNECTORS** 

## **AirMax VS2[®] BACKPLANE CONNECTOR SYSTEM** 

## **OVERVIEW** 

AirMax VS2[®] connectors provide a migration path from AirMax VS[®] for speeds up to 20Gb/s, providing margin of safety for typical 802.3ap system performance with the flexibility of an open pin field design. The connectors leverage AirMax VS[®] and VSe[®] design features and technology to achieve improved signal integrity and mechanical attributes compared to AirMax VS[®] connectors. 

The connector utilizes FCI technology for a shieldless design with no metallic plates and closely coupled differential pair design to yield low loss and low crosstalk. 

AirMax VS2[®] connectors are mating-compatible to both AirMax VS[®] and AirMax VSe[®] connectors and require no changes to connector PCB footprints. The mating-compatible interfaces and capability to preserve critical pin assignments can provide opportunities for cost savings as new and upgraded equipment is deployed. For example, a backplane or chassis can be designed to allow the installation and continued use of legacy daughter cards, line cards, or blades that are already in the field as well as new or future higher-speed module cards. 

Right angle and vertical receptacles and headers support backplane, midplane and coplanar applications. 

## **FEATURES** 

## **BENEFITS**

   - 0.5mm vias provide a drop-in replacement for VS parts 

   - Improved SI with the 0.4mm tails, same as VSe 

- Hard metric design practice 

- Can mix-and-match with other metric power and guidance components to create the precise system configuration that is needed
