Product Description
HDMI audio and video optical transceiver is used to extend the transmission of HDMI audio and video signals. It is usually used when the limit length of HDMI line cannot meet the transmission distance. This product transmits HDMI audio and video signals in high definition to the 20km client through optical fiber, up to 120km. The device supports TCP / IP network protocol, and can realize transmission from one transmitter to multiple receivers through the switch. While long-distance transmission, it supports local HDMI output, infrared return and independent audio transmission. It can remotely control the signal source (host KVM, TV box IR infrared) at the display end, While reducing the cost for users, it ensures the stability of the signal. The built-in EDID of HDMI audio and video optical transceiver greatly improves the compatibility of the equipment. The device has the advantages of long transmission distance, low cost, convenient installation and good compatibility. It is a stable and efficient transmission mode.
Widely used in information release system, security monitoring, video conference system, HD teaching system, LCD splicing screen, led splicing screen, engineering projection integration and other projects;
