Impel Backplane Interconnect System

Molex Impel Backplane Connector System achieves signal integrity, density, and data rates up to 40Gbps while enabling backward and forward compatibility. A compact, compliant-pin backplane connector enables backward and forward compatibility with various high-end architectures. 92Ω nominal impendence minimizes impedance discontinuities and multiple pitch options are available for design flexibility. The connectors deliver superior density and electrical performance, low crosstalk, low insertion loss, and minimal performance variations across all channels and frequencies to 20GHz. Molex Impel applications include telecommunications, data networking, industrial, and military/aerospace.
