Application cases of HDMI optical transceivers

Shenzhen Huatiancheng HDMI optical transceiver HDT/R-H81U/4S-20KM is used in multimedia information release and other application systems, and can transmit HDMI audio and video signals over long distances. If you use ordinary HDMI cables for long-distance transmission, the signal will be poor and easily interfered. The displayed image will appear blurred, smeared, color separated and other phenomena. If the transmission distance is short, it cannot meet the long-distance transmission requirements for multimedia information release and other occasions. Using Huatiancheng HDMI optical transceiver completely solves such problems.

Today we went to the Park Lane Hotel in Dongguan. After talking to their manager, we learned that they only have this large screen in a few important rooms. The other small rooms seem to have LCD TVs. They The transmission distance using an optical transceiver is actually not that far, almost 100 meters. The equipment solution is actually very simple, that is, the computer signal is transmitted to the large screen, and if the distance is far, the optical transceiver is used in the middle.

It turns out that the engineering contractor used another company’s products. Since the original optical cable was multi-mode, the effect was not very good in the process of realizing high-definition transmission. Based on the feedback from users, we know the specific solution. The product quality of the optical transceiver cannot meet the user's requirements. The other party requires the transmission of 1080P high-definition effect. However, since the HDMI optical transceiver provided by the other party is a product used in ordinary occasions, it cannot meet the user's requirements. In fact, what the customer requires can achieve Broadcasting and television-level video conferencing effects, 1080P images and pictures are continuously transmitted to various designated places. In order to cooperate with the other party's acceptance, our engineers first carefully measured the specific attenuation of the original multi-mode optical cable, and then transferred our HDMI optical transceiver to Increasing the power can ensure good image effects and also provide sufficient margin for later attenuation.

1. An industrial computer is installed in the switchboard room as an information source, and 4 HDMI optical transceivers (T) are installed as transmitters.

PS: The transmitter end of the optical transceiver (it should be advised not to stack it to avoid excessive temperature. He also said that the casing of this machine is very hot when it is working. Is there any problem? I said this is already made of aluminum. , if the iron is still hotter, the high temperature it can withstand is 60 degrees. I forgot to tell him about this stacking. I will talk to him tomorrow)

2. The information emitted by the transmitter is transmitted to the receiving room through optical fiber. , install HDMI optical transceiver (R) in the receiving room. Display the received video signal on a large screen.

3. Because the lobby of their hotel is close to the switchboard room, there is no need to use an HDMI optical transceiver. Each of the other four rooms is equipped with an HDMI optical transceiver (R) to project the received information on a large screen.

4. In order to let everyone understand in more detail how the HDMI optical transceiver is used in this project, we have refined the Park Lane Topology diagram of high-definition video transmission in Ning Hotel:

The above is the application case of HDMI optical transceiver in Berlin Hotel. The company has always adhered to the quality policy of "survive by quality and develop by reputation" to solve any practical problems of customers. , so that customers can use it with confidence.
