An HDMI or USB transmission is by definition limited in terms of distance, as the signal is attenuated. Thus, this HDMI / USB transmitter and receiver duo is the perfect solution to overcome this problem and allow transmission over long distances. Indeed, the signal is transmitted between the two boxes by optical fiber, making possible a transmission over a distance greater than 100m, without loss. Moreover, the transmitter is equipped with a USB-A port that can be connected to your computer for example, and the receiver has two USB-A plugs, this time to connect a keyboard / mouse combo. It is thus possible to act on the source device directly from the reception of the signal.
