It seems you're referring to a 1.5-meter USB extension cable. These cables are used to extend the reach of a USB device connection by providing additional length between the device (e.g., mouse, keyboard, external hard drive) and the computer or USB hub.

Typically, USB extension cables come with male and female connectors:

• Male USB connector: This is the end that connects to the computer or hub.
• Female USB connector: This is the end that connects to the device (like your mouse, keyboard, or USB flash drive).

The 1.5-meter length is a moderate length, often used in environments where the device or port is slightly out of reach, such as a desktop setup or when you need to connect a device that’s not conveniently located near the computer or power source.

Here are a few things to consider when buying such a cable:

• USB version compatibility (e.g., USB 2.0, 3.0, 3.1, etc.), as it affects the transfer speeds.
• Build quality (shielding, durability, etc.) for better signal integrity, especially for longer cables.
• Data and charging capabilities depending on the type of USB device you are using.
