1Ch 1080P HDMI + 1Ch USB KVM + 1Ch RS232 + 1Ch Bidi Stereo Audio + 1Ch GPIO over Fiber Extender Support general-purpose input/output (GPIO) signal

1Ch 1080P HDMI + 1Ch USB KVM + 1Ch RS232 + 1Ch Bidi Stereo Audio + 1Ch GPIO over Fiber Extender

Model: LNK-KVM-HDMI-1D1BA1GO

Overview

The LNK-KVM-HDMI-1D1BA1GO Fiber Optic Extender is a high-performance 1Ch 1080P HDMI +

1Ch USB KVM + 1Ch RS232 + 1Ch Bidi Stereo Audio + 1Ch GPIO over Fiber Extender, specifically

engineered to enable long-distance transmission of multiple critical signals via a single fiber optic cable.

As a 1Ch 1080P HDMI + 1Ch USB KVM + 1Ch RS232 + 1Ch Bidi Stereo Audio + 1Ch GPIO over Fiber

Extender, it integrates versatile signal transmission capabilities, making it an ideal solution for scenarios

requiring synchronized delivery of high-definition video, interactive control, and auxiliary signals across

extended distances.

This fiber optic extender supports HDMI signal extension with a maximum resolution of 1080P, ensuring

crisp, uncompressed high-definition video output—critical for applications where image clarity is non-

negotiable. Additionally, it incorporates 1Ch USB KVM functionality, allowing users to remotely control

connected devices (such as computers, servers, or industrial controllers) via USB peripherals, eliminating

the need for on-site operation. The integrated 1Ch RS232 port enables reliable data transmission for serial

devices like industrial sensors or legacy control systems, while the 1Ch Bidi Stereo Audio function ensures

bidirectional high-fidelity audio transmission, enhancing the immersive experience for video conferencing,

surveillance, or multimedia applications. The 1Ch GPIO port further expands usability by supporting general-

purpose input/output operations, enabling integration with external devices for customized control or monitoring.

With its excellent signal stability and robust security performance, the 1Ch 1080P HDMI + 1Ch USB KVM +

1Ch RS232 + 1Ch Bidi Stereo Audio + 1Ch GPIO over Fiber Extender is suitable for a wide range of professional

applications, including large-scale security surveillance systems, remote industrial control centers, corporate

video conferencing setups, digital signage networks, and educational or medical imaging environments. By

leveraging a single fiber optic cable for all signal transmission, it simplifies infrastructure deployment, reduces

cable clutter, and ensures consistent performance even over long distances, making it a reliable and cost-effective

choice for high-demand signal extension scenarios.
