Technical Architecture & Functionality
The Newnex FireNEX™-uLINK-40G (ULK40GLCC-4M) is a high-performance USB-C active cable engineered to extend full-speed USB4 / Thunderbolt performance beyond the limits of passive copper cables.
Supporting USB and Thunderbolt data rates up to 40Gbps, DisplayPort 2.0 Alt Mode (UHBR20), and USB Power Delivery up to 60W, this cable enables a single, reliable connection between modern hosts and high-performance devices such as high-resolution displays, docking stations, and external storage.
Unlike short passive cables, the uLINK-40G maintains maximum USB-C performance over a full 4 meters (13.1 ft.), using advanced active repeater technology to preserve signal integrity. It supports both 4-lane Display + USB 2.0 and 2-lane Display + USB 3.2 modes with automatic detection and switching, ensuring seamless compatibility across different device configurations.
The cable is fully plug-and-play, requires no drivers, and operates bi-directionally for USB Power Delivery, automatically selecting the appropriate power direction between host and device.
With a slim, flexible TPE jacket, full shielding, and VW-1 flammability rating, the FireNEX™-uLINK-40G is suitable for professional, industrial, and AV environments where reliability matters more than fashion.
