How the terabit class of pluggable cables and connectors is advancing

January 18, 2023 By Ed Cady Leave a Comment

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 […]

Will internal IO copper cables for data centers become standardized?

August 23, 2022 By Ed Cady Leave a Comment

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 are optical interconnects being miniaturized?

August 3, 2022 By Jeff Shepard Leave a Comment

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 […]

What’s different about space-rated connectors?

August 1, 2022 By Jeff Shepard Leave a Comment

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 […]

New developments in 212+G per-lane data-center connectors and cables

July 22, 2022 By Ed Cady Leave a Comment

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

July 5, 2022 By Ed Cady Leave a Comment

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), […]
