Hangzhou Feichang Technology HDMI optical transceiver is used in application systems such as multimedia information publishing, and can transmit HDMI audio and video signals over long distances. Long-distance transmission with an ordinary HDMI cable will result in poor signal and easy interference, and the displayed image will appear blurry, smearing, and color separation. If the transmission distance is short, it cannot meet the long-distance transmission requirements for multimedia information publishing and other occasions. The use of Feichang Technology HDMI optical transceiver can completely solve this kind of problem.
Today, we went to the Park Lane Hotel in Dongguan and talked with their manager and learned that they have this big screen in a few important rooms. Other small rooms seem to be that kind of LCD TV. The transmission distance of their optical transceiver is actually not. Far, almost 100 meters. The equipment scheme is actually very simple, that is, the computer signal is transmitted to the large screen, and when the distance is long, it is realized through the optical transceiver.
Originally, the engineering company used another product. Because the original optical cable was multi-mode, the effect was not very good in the process of realizing high-definition transmission. Based on the situation reported by users, we knew that the product quality of the optical transceiver was not up to the specific level. The request of the user, the other party requires the transmission of 1080P high-definition effect, but because 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 is to be able to achieve the broadcast-level video conference effect. The 1080P images and pictures are transmitted to each designated place coherently. 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 after returning, the power of our HDMI optical transceiver was increased to ensure that The image effect is good, and it also provides enough margin for the later attenuation.
1. An industrial computer is installed in the switchboard room as the information source, and 4 HDMI optical transceivers (T) are installed as the transmitter.
PS: Transmitter end of the optical transceiver (it should be advised not to stack it to avoid high temperature. He also said that the shell of this machine is very hot when it is working, will there be a problem? I said this is already made of aluminum, if the iron is still hot , The high temperature that can withstand is 60 degrees.)
2. The information transmitted by the transmitting end is transmitted to the receiving room through optical fiber, and the receiving room is equipped with an HDMI optical transceiver (R). Display the received video signal on the large screen.
3. Because the lobby of their hotel is relatively close to the switchboard room, there is no need to use HDMI optical transceivers. The other 4 rooms are each equipped with an HDMI optical transceiver (R) to display the received information on a large screen.
4. In order to let everyone know more about how the HDMI optical transceiver is used in this project, we have detailed the topological diagram of the HD video transmission of the Park Lane Hotel:
Well, the above content is the application case of HDMI optical transceiver in Berlin hotel.
