Junkosha Showcases Range of mmWave Cabling Solutions Designed for a 5G/6G Digital Future at DesignCon 2021

August 16, 2021

America’s largest chip, board and systems event, DesignCon 2021, has been chosen as the setting for Junkosha to unveil its wide range of cabling solutions—including the MWX6 Series and MWX001—all designed to meet the demands of a 5G/6G digital future. The quest for ever faster data transfer speeds has driven the newest generation of data centre systems to deploy optical fibre between components. The requirement for ultra-high performance cables to test and monitor the integrity of digital signals has become equally critical. Junkosha is leveraging its pedigree in analogue microwave and mmWave transmission performance and adapting it to the digital world. For example, working with Richardson Electronics in their support of major test equipment manufacturers worldwide, Junkosha is developing solutions that remove existing bottlenecks and opens the way to a new age of speed.     

Chris Marshall, CTO of Richardson Electronics, commented that, “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. This was an area of unmet need within the cabling and interconnect market that demanded focus and innovation to solve.”

For example, cabling solutions like Junkosha’s MWX001 cable assembly feature the lowest insertion loss among any cables for test measurement applications that demand signal stability whilst providing the physical cable flexibility required for test set-ups. As a result, the interconnect has become a premium choice for testing components within optical fibre communications systems. Cable insertion loss is minimized due to its cable structure, which is optimized for measurement up to 110 GHz with 1psec skew matching. MWX001 also exhibits excellent phase stability, leading to high quality signal transmission complete with predictable skew performance, a prerequisite for signal integrity applications.

In another example, Junkosha’s MWX6 Series provides highly precise skew matching with less than 1 psec 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 26.5 to 67 GHz.

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,” continued 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 is the place for chip, board and systems design engineers to source, network and stay ahead of industry change. The event provides visitors with an opportunity to review and discuss next-generation technology developments with relevant and interested parties such as engineers, professionals and leading industry figureheads. It also offers a forum to discover breakthrough innovations, take part in networking events and educational sessions. The event is being held at the San Jose McEnery Convention Center in California, from August 16 to 18.
