High-speed rugged D-Sub connector series for space applications

Provider of technically differentiated electronic components, Smiths Interconnect, has announced the introduction of the innovative split pair quadrax contact technology to its rugged D-Sub connector Series. The split pair quadrax is the next generation contact that provides robust high-speed performance compatible with existing qualified rugged D-Sub connectors.

Existing twinax contacts support data rates of above 10Gbps, but this performance is typically achieved at the cost of signal density in the architecture. Smiths Interconnect has designed a solution that isolates the individual pairs within the quadrax format in existing, space qualified, interconnect systems. The resulting isolated pair contact fits within existing housings and supports high density data rates exceeding 10Gbps.

The Rugged D-Sub connectors with split pair quadrax contacts support all mechanical and environmental performance parameters with enhanced electrical signal integrity. The innovative isolated pair contact system is an ideal solution with individual twinax pairs within the quadrax format through the cable and contact.

The new extended range meets the high-speed application requirements of the Space and Mil/Aero markets. These demands include the ability to reliably transmit and receive 10 Gbps and beyond with a stable characteristic impedance of 100Ω and compliance to all MIL-STD-202 requirements for shock and vibration.

“Smiths Interconnect’s rugged, reliable and high-performance solution is ideal for applications requiring high speed data transfer under extreme environmental exposure,” said Paul Harris, VP Sales and Marketing. “The reverse gender, high speed performance quadrax contacts provide a stable, optimised impedance for signal integrity and are key additions to our product portfolio delivering a competitive edge to our customers."
