ZY-OD921 4K@30Hz DVI mini optical transceiver is a high-performance device designed specifically for professional audio and video transmission. Adopting DVI-D pure digital signal interface, supporting up to 4K@30Hz Resolution, and backward compatible with all common resolutions such as 1080p, 1080i, 720p, etc.
The device achieves ultra long distance transmission of audio and video signals through optical fibers, and when paired with OM4 multimode optical fibers, the transmission distance can reach up to 300 meters without signal attenuation or interference. Using 10.2Gbps video bandwidth (3.4Gbps/CH) to ensure perfect 4K image quality presentation.
The product adopts a mini design, with compact TX/RX size and easy installation. The working temperature range is 0 ℃~55 ℃, suitable for various harsh environments. Both TX and RX require independent power supply through a DC 5V interface to ensure stable system operation. Widely used in scenarios such as large screen display, security monitoring, multimedia teaching, video conferencing, industrial control, etc.
