DVI Fiber Optic Extender with RS232 and Bidirectional Audio for Long-Distance HD Transmission

DVI Fiber Optic Extender with RS232 and Bidirectional Audio for Long-Distance HD Transmission

Overview

The LNK-DVI-1D1BA Fiber Optic Extender is designed to transmit high-definition DVI video, RS232

control signals, and bidirectional stereo audio over a single fiber optic cable. Supporting video

resolutions up to 1080P, this fiber DVI extender ensures lossless signal quality, high reliability, and

secure long-distance data transmission.

Engineered for industrial control systems, broadcast studios, medical imaging, and surveillance

applications, it delivers stable video performance, low latency, and superior noise immunity. With

its plug-and-play design and robust optical transmission technology, the device provides an ideal

solution for projects requiring high-quality video extension and long-distance communication over

fiber networks.

Features

Long-Distance DVI Transmission: Extends DVI digital video, RS232 serial control, and stereo

audio signals up to 20km through a single-mode or multi-mode fiber optic cable, ensuring consistent

and secure optical data transmission.

Full HD Resolution Support: Delivers crystal-clear image quality up to 1920×1200@60Hz and provides

enhanced compatibility for 1600×1200@60Hz display systems.

Bidirectional Audio Channel: Enables two-way stereo audio communication, allowing real-time

sound transmission between devices without distortion or latency.

Standards Compliance: Fully complies with DVI 1.0 and HDCP 1.2 protocols, making it compatible with

a wide range of monitors, projectors, and KVM systems.

Auto Signal Optimization: Features an intelligent signal correction and adjustment system that

ensures smooth, flicker-free, and high-fidelity video output over long distances.

High Compatibility & Stability: Supports auto-detection of video sources and displays, making it ideal

for mixed-system environments and industrial-grade communication setups.

Enhanced Protection: Built-in ESD and surge protection circuits safeguard the system from electrical

interference, ensuring long-term reliability and stable fiber transmission.

Easy Plug-and-Play Installation: No driver or configuration required — just connect and operate, ideal

for professional AV integration, control centers, and fiber-based signal extension projects.

Technical Indexes

Application

The DVI + Audio + RS232 Fiber Optic Extender is widely used in professional video and data

transmission systems that require reliable long-distance connectivity with zero signal degradation. It is
