Application

This multi-functional fiber optic extender is ideally suited for professional

environments requiring robust, long-distance, and high-fidelity signal transmission.

Its integrated support for video, KVM, serial data, audio, and control signals makes

it a perfect solution for:

Industrial Control & Automation Systems: Enables centralized monitoring and control

in factories and PLC-based environments by extending operator workstation interfaces to

remote machines over long distances, immune to EMI.

Broadcast & Pro AV Studios: Facilitates reliable transmission of HD video, bidirectional

audio for intercom, and RS232 for device control between production control rooms and

remote stages or OB vans.

Security & Surveillance Centers: Allows for the extension of HDMI video from security

cameras located at perimeter fences or remote buildings back to a central monitoring

station, including GPIO for alarm sensor inputs.

Digital Signage & Information Display Networks: Manages and distributes content to

displays in airports, shopping malls, or corporate campuses over fiber, with RS232 for

screen control and GPIO for power management.

Command & Control Rooms: Critical for mission-critical environments like traffic

management centers or utilities, providing stable extension of computer video, KVM for

operator control, and interfaces for status indicators.

Medical Imaging & Healthcare Systems: Ensures pristine transmission of diagnostic

images and data from MRI or CT scanners in isolated rooms to viewing stations,

maintaining signal integrity.
