What is an HDMI extender and what problem is it mainly used to solve?

An HDMI extender usually consists of a Sender and a Receiver. The transmitter is connected to an HDMI signal source (such as a computer, game console, etc.), and the receiver is connected to a display device (such as a TV, monitor, etc.). 

Signals are transmitted between the two devices via network cables (such as Cat5e, Cat6) or optical fibers. In this way, users can view and manipulate HD content at a longer distance without being affected by signal quality.

HDMI extender mainly solves the following problems:

Exceed the transmission distance limit of HDMI cable: Generally, the transmission distance of HDMI cable is less than 10 meters. The use of HDMI extender, the signal transmission distance can be extended to 50 meters 200 meters 

(network cable link) optical fiber transmission called HDMI optical terminal can be transmitted 500 meters to 20 kilometers or even farther, depending on the selected extender equipment (optical module).

Signal quality maintenance: During long-distance transmission, the signal may be interfered with or attenuated, resulting in degraded picture and sound quality. HDMI extenders or HDMI optical terminals, HDMI fiber cables can amplify and 

recover signals to ensure a high-quality audio and video experience.

Flexible layout: In some scenarios, such as conference rooms and advertising displays, the distance between the signal source and the display device may be far. The use of HDMI extenders can easily achieve signal transmission and

integrated wiring in these scenarios, improving layout flexibility.

The optical end of the HDMI extender is a practical device that can solve the problems of HDMI signal distance limitation and signal quality loss.
