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
InfiniBand
™
requirements. This I/O system has also been adopted by several other standards or MSA groups
in addition to InfiniBand
™
, 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.
