Junkosha aims mmWave test cabling line at 5G/6G digital future

Aug. 18, 2021
Junkosha says it is leveraging its pedigree in analog microwave and mmWave transmission performance and adapting it to the digital world by working with its partner Richardson Electronics in support of major test equipment manufacturers worldwide.

At the nation's premier chip, board and systems event, DesignCon 2021 (Aug. 16-18) in San Jose, CA, Junkosha has unveiled its wide range of cabling solutions – including its MWX6 and MWX001 series – all designed to meet the demands of a 5G/6G digital future, while fulfilling critical requirements for ultra-high-performance cables to test and monitor the integrity of digital signals.

Junkosha says it is leveraging its pedigree in analog microwave and mmWave transmission performance and adapting it to the digital world by working with its partner Richardson Electronics in support of major test equipment manufacturers worldwide. The partners say they are now developing solutions that remove existing bottlenecks and open the way to a new age of data transfer speeds, driven by the latest generation of data center systems deploying optical fiber between components.

Chris Marshall, CTO of Richardson Electronics, comments: “With the insatiable appetite for data, a premium is put not only on systems that generate, encode and deliver error corrected signals, but on the equipment that tests and verifies such systems. Our customers have developed state-of-the-art testers which are aligned with the needs of 5G/6G and beyond. Ultimately, the system is only as good as its weakest link, and we have worked with these partners on end-to-end performance enhancement and assurance."

"Elements such as preservation of skew performance in a number of test environments are critical for such customer assurance," Marshall added. "This was an area of unmet need within the cabling and interconnect market that demanded focus and innovation to solve.”

The partners note that cabling solutions such as Junkosha’s MWX001 cable assembly feature the lowest insertion loss among any cables for test measurement applications that demand signal stability, while providing the physical cable flexibility required for test set-ups. As a result, Junkosha says its new interconnect has become a premium choice for testing components within optical fiber communications systems.

Cable insertion loss is minimized due to the product's cable structure, which is optimized for measurement up to 110GHz with 1psec skew matching. The MWX001 also exhibits excellent phase stability, leading to high quality signal transmission, complete with predictable skew performance, a prerequisite for signal integrity applications.

For its part, Junkosha’s MWX6 Series provides highly precise skew matching with less than 1psec skew between pairs for the measurement of digital transmissions. This cable has low insertion loss, appropriate for measuring high-precision differential transmission signals. Four types of cables are available with a variety of frequencies, from 26.5GHz to 67GHz.

Masaru Omoto, product manager for Junkosha, explained: “With the help of Richardson Electronics, we are conducting optical transceiver testing using cabling solutions including the MWX001 and MWX6 series with the aim of delivering error corrected signals from the Bit Error Ratio Tester. From these tests, we can determine how well optical communications systems components will likely operate in their delivery of increasing amounts of data in real time; a critical requirement in the journey to successful 5G and ultimately 6G rollouts."

“At Junkosha, we are constantly innovating new precision engineered cabling solutions for an increasingly digital world,” concluded Omoto. “Our latest products we are showcasing at DesignCon 2021 all feature characteristics, including an ability to consistently test signal integrity without impacting performance, that are critical for the data transmission of the future which will be needed to handle the increasingly demanding end uses.”

DesignCon 2021 is being held at the San Jose McEnery Convention Center in California from August 16 - 18. For more information, visit https://www.designcon.com/en/home.html and https://www.junkosha.com/en/products/cable.
