MuxLab 500462 - High Security HDMI Optical Isolator Kit with Fiber Extension
The MuxLab 500462 is much more than a simple video extender; it's an advanced engineering tool designed for critical environments where data security and electrical integrity are paramount. This transceiver kit completely isolates HDMI equipment, creating a physical and optical barrier that eliminates any electrical (galvanic) connection between the signal source and the display. By using a fiber optic link, this device protects sensitive equipment from power surges, ground loops, and voltage spikes, ensuring clean and secure transmission.
Designed specifically for high-security applications and medical or industrial environments, the system operates using unidirectional communication . This means the signal travels strictly from source to destination without a return channel, acting as a "data diode" that prevents malicious software or information leaks from returning to the secure source network. Its ability to transmit video signals up to 4K UHD @ 30Hz or 1080p over distances of up to 300 meters makes it the ultimate solution for long-range professional installations.
Main Features
-
Total Galvanic Isolation: By replacing copper wiring with fiber optics, the risks of ground potential differences and electrical noise are eliminated, protecting both equipment and users (ideal for operating rooms and industrial plants).
-
Unidirectional Data Security: The system architecture physically prevents any return signal (no bidirectional DDC/HDCP return channel), blocking cyber vulnerabilities and unauthorized access to the source equipment.
-
Long Range over OM3 Fiber: Capable of sending crystal clear video signals up to 300 meters using a single OM3 multimode fiber cable with LC connector.
-
4K and 1080p Resolution: Supports resolutions up to 3840x2160 (30Hz) and Full HD 1080p, ensuring crisp image quality for precision monitoring and digital signage.
-
Compact and Robust Design: Its low-profile metal casing allows for easy integration behind monitors or in rack trays, minimizing the space occupied.
Benefits for critical environments
The MuxLab 500462 offers unparalleled operational peace of mind. For medical system integrators , it ensures that display screens in MRI rooms or operating theaters do not introduce dangerous electrical interference. In the defense and government sectors, its one-way operation ensures that a public display or projector in an unclassified area cannot be used as an attack vector to access the secure server network.
Use cases
-
Medical Facilities (Hospital Grade): Isolation of patient display systems to comply with electrical safety regulations and prevent electromagnetic interference (EMI) in sensitive diagnostic equipment.
-
Government and Military Security: Situation rooms and command centers where the visualization of classified data is required without risk of data leakage to external peripherals (Compliance with physical data security policies).
-
Heavy Industrial Environments: Factories with high-voltage machinery where ground loops degrade the video signal or burn out the HDMI ports of conventional equipment.
-
Data Centers and Server Rooms: Remote monitoring of consoles without compromising the integrity of the internal network.
Frequently Asked Questions
-
Does this device support HDCP-protected content (such as Blu-ray or Netflix)?
No. Due to its strict (one-way) security design, it does not handle the return handshake required for HDCP. It is designed for PCs, security cameras, medical equipment, and unencrypted proprietary content.
-
What type of fiber optic cable do I need?
Requires a single OM3 (50/125 μm) Multimode Optical Fiber cable with LC type connector termination.
-
Does it need power at both ends?
Yes, the kit includes two power supplies, one for the transmitter (TX) and one for the receiver (RX), guaranteeing the power needed for optical conversion.
-
Can it transmit IR or RS232 control signals?
No, this model is designed exclusively for isolating the HDMI video signal to maximize safety.
Project description
