The Lenovo CABL 4X91K16970 is a Thunderbolt 4 cable with a length of 0.7 m, specifically developed for use with the ThinkPad Thunderbolt 4 WorkStation Dock. It features two male connectors and enables a maximum data transfer rate of 40 Gbit/s, making it suitable for the fast exchange of large data volumes such as videos, music, or files. The cable is finished in black and has a cable diameter of 4.8 mm and a weight of 88 g, ensuring a compact and convenient design. The construction is tailored to the requirements of workstation docks, with the 0.7 m length supporting an organized workspace setup without the cable being excessively long or cluttered.

Applications
The cable is primarily intended for use with the ThinkPad Thunderbolt 4 WorkStation Dock. It serves as a replacement cable for users who have lost or damaged the cable included in the standard delivery. The special split-cable design enables simultaneous data and power transmission, with power delivery via USB-C supporting up to 100 W. Use is restricted to systems that support Thunderbolt 4 technology, particularly ThinkPad notebooks and compatible docks.

Functions and Equipment in Detail
The cable combines the functions of a data and power supply cable in one. The Thunderbolt 4 technology not only enables high data rates but also supports DisplayPort video outputs and power delivery through the cable. The maximum data rate of 40 Gbit/s is beneficial for professional applications such as video editing, 3D modeling, or accessing external storage devices. The cable construction is designed to meet requirements for stability and signal integrity at high transmission rates.

Technology Explained Simply
Thunderbolt 4 is an interface technology that transmits data, video, and power through a single cable. The data transfer rate of 40 Gbit/s corresponds to a very high speed, enabling large files to be transferred in seconds. The male connectors at both ends of the cable are designed for direct connection to Thunderbolt 4-compatible devices. The power delivery via USB-C up to 100 W is sufficient for charging notebooks, with the exact power consumption depending on the connected device. The cable is designed for use in office environments where a stable and reliable connection is required.

Compatibility and Accessories
The cable is specifically developed for the ThinkPad Thunderbolt 4 WorkStation Dock and is used in conjunction with ThinkPad notebooks. It is compatible with devices that support Thunderbolt 4. Use with other docks or devices that are not Thunderbolt 4-compatible is not intended.

Installation and Mounting
Installation is carried out by simply connecting the two male connectors to the corresponding sockets on the ThinkPad notebook and the Thunderbolt 4 WorkStation Dock. The connection is plug-and-play, with the systems automatically recognizing and configuring the connection. No additional drivers or software installations are required, provided the devices are Thunderbolt 4-compatible.

Operational Advantages
The cable provides a reliable and fast connection between notebook and dock, making workspace configuration more efficient. The cable length of 0.7 m reduces cable clutter on the desk and allows for neat placement of devices. The support for power delivery and data transmission over a single cable reduces the number of required connections and simplifies workspace setup. Certification according to RoHS, REACH, and UL62368 ensures compliance with environmental and safety standards.
