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 […]
How QSFP-DD and OSFP Loopback modules are supporting multiple IO interfaces
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), […]
Why connector return loss causes signal problems
Return loss can affect insertion loss, the amount of energy that reaches a receiver.
Driving standards: The latest liquid-cooling cables and connectors for data centers
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 […]
D-sub connectors: Everyone speaks of them incorrectly
You probably don’t know it, but you’ve been referring to most D-sub connectors incorrectly for your entire career.
What is the common impedance of a twisted pair?
Understanding impedance in twisted-pair cables help you avoid signal problems.
The connector is often the EMI problem
It only takes 3µA of current to fail an EMC test, and a connector can produce that much.
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 […]
The evolution of woven fiber optic circuit boards and connectors
During the ’60s and ’70s, the early mainframe computers and Telcom switches used complex dense wire-wrap technology. High-circuit-count copper backplanes and midplanes often relied on wire-wrap point-to-point, or pin-to-pin layouts. This involved lots of hook-up wire and singular micro-coax for the clock circuits. The wire-wrap pin backplane connectors at that time typically had round-wired edge […]
Four types of connectors for robots and drones
Many power and signal connectors are used in robot and drone sub-systems, such as sensors, motion, high-speed wired and wireless communications, and more. As industry 4.0 continues to unfold, more robots and more types of robots are being found in factories, warehouses, and other facilities to increase quality and efficiencies and reduce costs. Robots and […]
