DCI pluggable connectors support evolving applications

May 29, 2024 By Ed Cady

IO interface groups are supported by AI developers, HPC, Enterprise, and other market segment leaders, driving connector/cabling solutions using higher speed rates, varying lane counts, and pin counts. Besides supporting the very high volume pluggable Hyperscale market segment, various pluggable connector systems support other new applications and network topologies that are driving the use of […]

Connector and cable interconnects solving problems and providing a path forward

May 7, 2024 By Ed Cady

Past and current data center hardware systems developers occasionally require and evaluate unexpected or previously unimagined connectivity solutions. These novel solutions often require a very short development cycle and low cost of ownership targets. Leading-edge test and measurement equipment developers sometimes need a good fast solution as a bridge product before qualifying a new connector […]

How internal fiber-optic connector designs are advancing

October 19, 2023 By Ed Cady

Inside-the-box copper connector and cable IO-Link standards for data centers have been a significant focus of systems product development, particularly within consortia and industry standards groups. Some recent examples are internal 400G and 800G PECFF Top-of-Board, Ethernet, CXL, and the PCIe use of SFF TA 1002/1020 connectors. Other examples include twin-axial cables for memory, storage, […]

How high pin-count socket connectors are supporting new processor-chip applications

February 7, 2023 By Ed Cady

Datacenter server processor chips have proven valuable as pluggable and removable devices for the socket connectors mounted to a server’s main PCB board. However, the number of contacts per socket connector has dramatically risen over the last few years. New chips offer 3000 to 5000 or more contact pads per flip chip.  Typically, the socket […]

How the terabit class of pluggable cables and connectors is advancing

January 20, 2023 By Ed Cady

The world of gigabits began some 25 years ago, with a progression of interface lanes and links — from 100G and 200G to 400G and then 800G using IO standard and proprietary connectors and cables. Believe it or not, gigabit lanes were first used in 1999. Today, we’re entering the terabit phase with interface links […]

How new USB4.2 80G cable links will support cost-effective connectivity

October 26, 2022 By Ed Cady

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 […]

Will internal IO copper cables for data centers become standardized?

August 25, 2022 By Ed Cady

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 […]

How QSFP-DD and OSFP Loopback modules are supporting multiple IO interfaces

July 6, 2022 By Ed Cady

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), […]

Driving standards: The latest liquid-cooling cables and connectors for data centers

June 7, 2022 By Ed Cady

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 […]
