Industrial DVI Fiber Extender with 1080P HD Video RS232 Control Audio

Signal Transmission

Overview

The LNK-B-DVI-1DA1GO Fiber Optic Extender is a high-performance solution designed to transmit

1080P DVI video, bidirectional RS232 control signals, stereo audio, and GPIO data over a single

fiber optic cable. Supporting Full HD resolutions up to 1920×1080@60Hz, this DVI over fiber

transmitter and receiver pair ensures lossless image quality, real-time signal transmission, and

long-distance communication up to 20–60km depending on the fiber type.

Engineered for professional AV integration, control systems, and industrial automation, the

extender provides bidirectional communication, stable data transfer, and excellent electromagnetic

interference immunity. With plug-and-play design, ESD protection, and auto-adjustment technology,

it offers a reliable, secure, and easy-to-install solution for applications that require high-quality video,

audio, and serial data transmission over long distances.
