Product Overview
What the ML-HDIFBT101 and ML-HDIFBR101 deliver
The HDMI IR Over Fibre system from Milestone Electronics consists of two units: the ML-HDIFBT101 Transmitter and the ML-HDIFBR101 Receiver. Together, they extend HDMI video and IR control signals over a single mode, single fibre SC cable to distances of up to 10 kilometres. This makes it a purpose-built solution for installations where HDMI source equipment and display devices are separated by very long distances that standard copper-based extenders cannot cover.
The system supports video output up to 1080P Full HD and is HDCP compliant, ensuring compatibility with protected content sources. The plug-and-play design requires no complex configuration and works with all standard HDMI ports on both source and display equipment.
Both units feature six LED indicators on the rear panel displaying real-time status for power, Fdx/co, Fx Link/Act, Tx Link/Act, Fx100, and Tx100. This allows engineers and AV technicians to verify link health at a glance without requiring additional diagnostic equipment. A reset switch is also provided on each unit to recover from any abnormal display conditions that may occur after initial connection.
In addition to HDMI video, the system carries IR signals. An optional IR LED cable can be connected at the IR OUT port on the Transmitter, and an optional IR Sensor cable at the IR IN port on the Receiver, enabling remote control of the HDMI source device from the display location. Note that the IR LED and IR Sensor cables are not supplied with the units and must be sourced separately.

FAQs about the HDMI IR Over Fibre
What is the HDMI IR Over Fibre (ML-HDIFBT101 and ML-HDIFBR101) used for?
The HDMI IR Over Fibre system is used to transmit or distribute HDMI video and optional IR control signals from a source device to a display over distances of up to 10 kilometres using a single mode, single SC fibre cable. It consists of two units: the ML-HDIFBT101 Transmitter and the ML-HDIFBR101 Receiver. It is designed for installations where source and display equipment are separated by distances that exceed the capabilities of standard copper-based HDMI extenders.
What type of fibre cable is required for this system?
The system requires a single mode, single fibre SC cable. Both the Transmitter and the Receiver are fitted with SC Fibre Connectors, and only one fibre cable is needed to carry both the HDMI and IR signals between the two units. Multi-mode fibre cable is not specified for this product and the single mode SC cable type must be used to achieve the stated 10 km transmission distance.
What video resolutions does this extender support?
The ML-HDIFBT101 and ML-HDIFBR101 support video resolutions up to 1080P Full HD. The system is also HDCP compliant, which means it is compatible with source devices that output HDCP-protected content, such as Blu-ray players, set-top boxes, and media servers. Both units maintain the same maximum resolution of 1080P Full HD.
Is IR control included with the units, and what cables are needed?
IR control is supported as an optional feature on both units. The ML-HDIFBT101 Transmitter has an IR OUT port for an IR LED cable, and the ML-HDIFBR101 Receiver has an IR IN port for an IR Sensor cable. However, the IR LED cable and IR Sensor cable are not supplied with the units and must be obtained separately. IR control is not mandatory for HDMI video operation and can be added when remote source device control from the display location is required.
What does the reset button on each unit do?
Both the Transmitter and Receiver have a reset switch located on the rear panel. This switch should be pressed if any abnormal display condition is observed after all cables and displays have been connected and both units have been powered on. The reset function restores normal operation without requiring the user to disconnect and reconnect the fibre or HDMI cables, and is part of the standard troubleshooting procedure recommended in the product manual.
What information do the LED indicators on each unit display?
Each unit has six LED indicators on the rear panel that provide real-time status monitoring. These LEDs display the status of power, Fdx/co (full-duplex or collision), Fx Link/Act (fibre link activity), Tx Link/Act (transmit link activity), Fx100 (fibre 100 Mbps), and Tx100 (transmit 100 Mbps). This allows installers and technicians to confirm power-on status and verify the health of the fibre link at a glance without requiring separate diagnostic equipment.
Does the system work with any HDMI source and display device?
Yes. The system is compatible with all standard HDMI ports on both source and display devices. Installation is plug-and-play, requiring no software configuration or drivers. The HDMI input on the Transmitter accepts any HDMI-equipped source device, and the HDMI output on the Receiver connects to any standard HDMI-compatible display, monitor, or projector. HDCP compliance ensures that protected content sources are also supported.
What power supply is required for each unit?
Both the ML-HDIFBT101 Transmitter and the ML-HDIFBR101 Receiver require a 5V/2A power supply. Each unit is powered independently, so two power supplies are needed for a complete installation. Both units must be powered on for the system to operate. Power should be applied to both units after all HDMI and fibre connections have been made.
