Application
This professional-grade fiber optic extender is engineered for environments
requiring reliable, long-distance transmission of high-definition video, interactive
audio, and serial control signals. Its specific interface configuration makes it ideal for:
Industrial Control Systems: Enables centralized monitoring and operation by
extending control workstation interfaces to remote PLCs and HMIs over fiber, with
RS232 for device control and bidirectional audio for intercom.
Broadcast & Live Production: Facilitates reliable transmission of camera feeds
(HDMI) and two-way audio communication between the stage/field and the
production control room, with serial control for PTZ cameras.
Security & Surveillance Centers: Allows for the consolidation of signals from
remote security setups, transmitting HD video from cameras, audio from area
microphones, and RS232 for PTZ control back to a central monitoring station.
Digital Signage & Corporate AV Networks: Manages content distribution to
displays across large campuses or buildings, utilizing RS232 for display power
management/power on/off and bidirectional audio for synchronized sound.
Medical Imaging & Diagnostic Viewing: Ensures pristine transmission of medical
imaging data from diagnostic equipment in shielded rooms to remote diagnostic
review stations, maintaining signal fidelity and compliance.
Distance Learning & Conference Systems: Extends presentation video (HDMI)
and supports two-way audio for Q&A sessions between a main hall and remote
overflow rooms or recording studios.
