Molex Brings Out a PCIe Connector System and Cable Assemblies for Next-gen Servers

Molex, which provides solutions in automotive, data center, industrial Automation, healthcare, 5G, cloud, and consumer devices industries introduces PCIe Cable Connection System for Open Compute Project Servers.

Initially, the PCIe Cable Connection System for Open Compute Project Servers namely NearStack PCIe Connector and Cable Assemblies is replacement for the classic paddle-card cable solutions and it highlights a direct-to-contact twinax termination in which it puts an end to hand-soldering cables onto a PCB paddle card. Moreover, the NearStack PCIe has a topnotch construction  which is perfect for  Gen-6 system implementation.
