ABS announces the launch of its VIPER™ connector – a powerful new backplane and daughtercard interconnect platform providing 63 differential signals per linear inch. The VIPER™ connector has been designed to meet the demanding requirements of the next generation of rugged military and aerospace applications and is currently being incorporated into the VPX family of specifications as VITA 60.

ABS developed the VIPER interconnect platform after extensive voice of the customer (VOC)interviews. These interviews drove us to meet or exceed future avionic high-level vibration, mechanical shock and condensing moisture test requirements. Customers emphasized the need for ruggedization in the next generation of military packaging solutions that can scale to higher bandwidths without costly and time-consuming chassis redesigns. The VIPER connector platform offers the ability to scale from 80 Mbps to over 10 Gbps while retaining the same Vita 46 backplane slot pitch at 20.3mm to 25.4mm.

VIPER™ is a shielded, high-density, high-speed press-fit, modular interconnect system. Optimized for differential pair architectures on a 1.8mm x 1.35mm grid, the waferized daughtercard assembly also provides single-ended and power wafer options integrated onto a stainless steel stiffener with stainless steel guidance and keying blocks.

The backplane modules are available in 8 and 16 row increments on a 1.8mm x 1.8mm grid, with integrated stainless steel guide-pins and fully user-configurable keys – eliminating the dependence on PWB “notches” driving pre-determined module keying. The new backplane signal contacts incorporate a highly reliable 4-points-of-contact beam design and the ground contacts leverage Amphenol’s 35-year experience with robust compliant pin and contact fork designs. The daughtercard and backplane contacts are stamped using Olin’s high quality C7025 copper alloy and plated using nickel underplate with 50 microinches of gold on all mating surfaces. Design variations, including RF and fiber optic modules (VITA 66 and 67) into the VIPER™ stiffener assembly, are available as well as the standard 3U and 6U catalog configurations.

Designed for harsh environments, Amphenol’s proposed VITA-66 MT connector provides a reliable high speed connection for the most extreme commercial and military environments. With up to 24 fiber optic channels per MT ferrule and 48 channels per connector it is among the highest density connector on the market.

ABS developed the VIPER™ interconnect platform after extensive Voice of the Customer (VOC) interviews. These inputs drove ABS to meet or exceed future avionic high level vibration, shock and condensing moisture test requirements. Following the need for ruggedization in future packaging solutions that can also deliver more bandwidth down the road without the need for costlyand time-consuming redesign, the VIPER™ connector system gives our customers the ability to scale from 80 Mbps up to 10 Gbps while maintaining their 0.8’ to 1.0” slot pitch and chassis design.
