5 GHZ Bi-directional 4 Lane I/O Connector System with Superior Mechanical Reliability

The Molex 4 Lane I/O connectors incorporate an industry compatible mating interface compliant with Infi niBand™ requirements. This I/O system has also been adopted by several other standards or MSA groups in addition to Infi niBand™ , noted below. LaneLink™ is a 100 ohm cable to board I/O system optimized for differential signaling at 2.5 Gbps per pair. The Molex design features superior mechanical reliability and an extensive range of options including Latching and Jackscrews versions. A recent feature to both 4x options is the addition of a landing area for automated Pick and Place. EMI shielding has now been improved by adding a rear EMI shield to reduce EMC/EMI leakages.
