Commercial-grade DVI extender over fiber
Product Details


Commercial-grade DVI extender over fiber is used to extend the transmission of VGA audio and video signals,which is usually used when the DVI cable limit length cannot meet the transmission distance.This product transmits DVI audio and video signal to 20KM user through the fiber, up to 120KM, equipment supports TCP/IP network protocol, can realize one transmitter to multiple receiver transmission through ethernet switches,long-distance transmission while support infrared return transmission, independent audio transmission,to ensure the stability of the signal while reducing the cost for the user.the EDID built-in audio of commercial-grade HDMI extender over fiber greatly improves the compatibility of the device.The equipment has a long transmission distance, low use cost, convenient installation, good compatibility, and is a stable and efficient transmission mode.

Widely used in information release system, security monitoring, video conference system, hd teaching system, LCD splicing large screen, LED splicing screen, engineering projection fusion and other projects.
