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.
