The USB Promoter Group recently announced the November release of the USB4 Version 2.0 specification, a significant update to enable up to 80 Gbps of data performance over the USB Type-C cable and connector. The USB Type-C and USB Power Delivery (USB PD) specifications will also be updated to enable this higher level of data […]
Demands for bandwidth-intensive, data-driven services are fueling a rise in compute, data storage, and networking capabilities. These rises put pressure on connectors and cable to deliver data at higher speeds with better signals and less heat.
Data-center passive DAC external cables have been standardized and interoperable for decades. However, the mating, inside-the-box cables have yet to be fully standardized. In general, inside-the-box IO interface interconnections have been a competitive value point for those OEMs and suppliers that offer quality options. Providing reliable connectors and twin-axial cables configured in an ideal layout […]
Fiber optic connector trends include a proliferation of new and smaller designs and, according to NTT, optical connector standardization activities are one of the most active areas at the International Electrotechnical Commission (IEC). As of February 2021, IEC SC 86B (Fibre optic interconnecting devices and passive components) published the second largest number of documents in […]
Space-grade connectors are generally spin-offs of military-grade designs. Compared with common commercial connectors, there’s a much smaller variety of space-grade connectors. However, commercial off-the-shelf (COTS) and COTS+ connectors are increasingly used in cost-sensitive missions such as CubeSats. This FAQ begins with a look at the unique operating conditions in space and how those conditions impact […]
Several deep-packet inspection chips and test instrumentation applications are using next-generation speed-rate IO application-specific integrated circuit (ASIC) chips. These chips combine several circuits in one and are customized for a particular use. This is different than what the current server and switch markets are typically using. These developers are experienced with the 200+ per lane […]
IO Loopbacks connect digital data streams to their source without purposeful processing or modification. This serves as a diagnostic test for a device and other nodes in the network infrastructure. The return signal is compared with the transmitted signal. For several generations of electronic equipment, using a short cable assembly, molded very-high-density cable interconnect (VHDCI), […]
Return loss can affect insertion loss, the amount of energy that reaches a receiver.
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 […]
You probably don’t know it, but you’ve been referring to most D-sub connectors incorrectly for your entire career.
