The Digitus Keystone module telephone adapter USB 3.2 Gen 1, USB-A female to USB-A female is a practical connecting element intended for integration into modular systems such as patch panels or built-in wall sockets. It belongs to the category of telephone adapters, where it enables simple and reliable connection of USB devices using standard Keystone modules. It is intended for those who want to enable data transfer and power supply via a USB interface in their network or electrical installation in a simple and elegant way.

The adapter is based on USB 3.2 Gen 1 technology, which supports data transfers up to 5 Gbit/s. This means you can quickly transfer large amounts of data or use devices that require more bandwidth, such as high-definition webcams or external hard drives. With a USB-A female to USB-A female interface, it allows you to connect various types of devices with a USB-A cable, eliminating the need for special converters or additional cables.

The adapter is designed to mount into a standard Keystone hole, allowing for flexible integration into existing communication or electrical systems. This makes it a particularly useful choice in office environments, classrooms, home workspaces, or anywhere you want a conveniently accessible USB port on a wall or furniture surface.

The metal housing and black color further ensure durability and discreet placement in a modern environment. Thanks to the modular design, you can easily replace or upgrade connectors without interfering with the entire installation, which reduces the time and cost of future network or room adjustments.

It is important to know

Before purchasing such adapters, it is crucial to understand what exactly they enable and what limitations they bring regarding use with your devices. The biggest difference in practice comes from the compatibility of the connectors and limitations in functionality, which are not always obvious from the technical data. Pay special attention to expectations regarding data transfer and possible multifunctional use.

• The adapter with dual USB-A ports is mainly useful for connecting two devices with a classic USB-A interface, but does not support connection to devices that use USB-C, Micro-USB, or Lightning.
• Support for USB 3.2 Gen 1 enables fast data transfer (up to 5 Gbit/s), but the final speed also depends on the devices and cables you use.
• The adapter is not designed for fast charging - if this is a priority need, check whether your devices and cables even support the USB-A fast charging standard.
• When using different cables, make sure that each one in the entire chain has the appropriate quality and standard, otherwise you may limit functionality or data transfer speed.
