Passive and active direct liquid cooling for modules and chassis immersion implementations are becoming more commonly used to cool high-wattage devices — such as graphics processing units (GPUs) and switch application-specific integrated circuits (ASICs). This seems to be driving an expanding fluid connector and cable market with higher-volume units as applications now include hyperscaler and […]

Wire and fiber optic geometries offer high-speed cable transmission options
The latest high-speed transmission cables are benefitting from the use of optic-fiber and copper wire options, which are offering unique form factors and customizable solutions. Typically, data-transmission copper wire and optical-fiber conductors are round or cylindrical. The addition of silver plating on the copper conductor facilitates the high-frequency electrical transmission path. Fiber conductors are foundry […]
How the digital-interface standards for cables and connectors are changing
CoaXPress (CXP) is a popular, digital-interface standard developed for high-speed transmission of data, videos, and still images. This interface was introduced in 2008 and has been used in industrial automation for years, with advanced machine vision and robotics applications following suit. It has been driven by reliability and simplicity, which includes its cables and connectors. […]
How system fabric I/O interface cables and connectors are evolving
Newer fabric network input/output (I/O) cables and connectors support higher speeds, reduce latency, and support the latest interfaces — including the IEEE-802.3df Ethernet 200G per-lane specification project and modified versions, such as the RoCE and iWARP Ethernet. Other new cable and connector developments are working to include standard InfiniBand XDR 200G and modified versions, such […]
How PCIe interface developments have changed and advanced
By Ed Cady, contributing editor Peripheral component interconnect express, or PCIe, has become the interface standard for connecting high-speed components, such as graphics, memory, and storage. Typically, PCIe interface signaling and physical layer implementation rely on printed circuit board assembly (PCBAs) and edge connectors. Several standardized and non-standardized cabling solutions are available that support a […]
