Molex Introduces PCIe Cabling System for Open Compute Project Servers

NearStack PCIe Connector System and Cable Assemblies Use New Direct Attach Cable Technology to Improve Signal Integrity, Lower Insertion Loss and Reduce Signal Delay

Developed in collaboration with members of the Open Compute Project, NearStack PCIe is a key component of next-generation servers

Developed in collaboration with members of the Open Compute Project (OCP), NearStack PCIe replaces traditional add-in card cable solutions to optimize signal integrity and improve system performance.

A standout feature of NearStack PCIe is its direct-contact twinax termination, which eliminates the need for add-in cards in the cable assembly. Unlike competing cable jumpers that are terminated by hand-soldering cables to PCB paddles, NearStack uses a fully automated wire termination process. This high-precision process improves manufacturing efficiency, repeatability, and signal integrity.

Due to its superior architecture, NearStack PCIe is ideal for next-generation PCIe Gen-5 and Gen-6 system implementations, The product's ability to reach 32-Gbps NRZ data rates enables server OEMs to achieve unprecedented performance.

Mechanical design optimizes space and simplifies integration

Molex optimizes cable assemblies for efficient use of space as well as secure and easy connections. Smart, robust mechanics, and an optional "corner exit" cable design allow technicians to easily insert jumpers into crowded circuit boards. In addition to alleviating space constraints, NearStack PCIe offers a low profile to improve airflow management and minimize interference with adjacent components.

NearStack PCIe further simplifies integration by supporting hybrid cables, using a NearStack PCIe connector on one end and a traditional connector on the other. These connectors provide a simplified upgrade path for existing equipment, enabling customers to immediately take advantage of new technologies without having to redesign or replace current hardware.
