How should HDMI be transmitted over long distances?

1. A conversion extender can be used
　　HDMI signals do not go through other devices (transmission 120 meters), HDMI signals generally can not be directly transmitted with HDMI cables to more than 30 meters, and it is almost impossible to buy a finished HDMI cable of more than 30 meters.
　　In this case, if the HDMI signal is simply transmitted to the display device, the HDMI signal does not go through other devices, we can use the network cable to extend the signal, with HDMI network cable extender to extend the signal, HDMI network cable extender is divided into the transmitter (HDMI input, network cable output) and the receiver (network cable input, HDMI output), can extend 100 meters ( Category 5 network cable), 120 meters (Category 6 network cable).
2.Optical HDMI cable
　　There are many ways about HDMI extension, fiber HDMI cable is also an option for long distance transmission of HDMI signal. It can be used according to the actual situation.
