At CES 2023 in Las Vegas (Jan. 5 - 8), Spectra7 Microsystems Inc. (TSXV: SEV), a provider of analog semiconductor integrated circuit (IC) products for data centers, 5G infrastructure, virtual and augmented reality, and other connectivity markets, is collaborating with connector and cable supplier Advanced-Connectek USA Inc. (ACON); and Mo-Link Technologies Limited, a global provider of fiber-optic, copper, and wireless connectivity technology, to jointly demonstrate a Thunderbolt 4 active copper cable (ACC) employing Spectra7's GC2502 GaugeChanger ICs.

Value proposition

Spectra7 said its GaugeChanger brand defines "a unique analog redriver technology that allows copper to extend to much longer lengths without the cost and power penalty of optics or retimed copper solutions."

As employed in the demo, Spectra7's GC2502 ICs enable Thunderbolt 4 protocol at rates up to 40Gb/s over 2 meters of 30AWG copper cable, which is twice the distance achievable with passive cables.

At CES 2023, ACON together with Mo-Link is demonstrating a 2-meter Thunderbolt 4 ACC connecting between an Apple MacBook Pro and an LG 40'' Curved UltraWide 5K2K Nano IPS monitor with Thunderbolt 4 connectivity.

Mo-Link is showcasing the Thunderbolt 4 cable, as well as other innovative connectivity technology, under the brand name "Storhm," its retail brand for the North American market.

The CES demonstration is to be found in CES booth #18934 this week at the Las Vegas Convention Center.
