An HDMI fiber extender is a device that uses optical fiber cables to transmit high-definition audio and video signals over very long distances without compromising signal quality. Unlike standard HDMI cables, which suffer from signal degradation over long runs, fiber optic extenders can maintain uncompressed 4K or 8K resolution over several kilometers.
The system consists of two main units:
A transmitter (TX) unit connects to your video source (like a computer, console, or media player) via a short HDMI cable. It converts the electrical HDMI signal into an optical signal.
A receiver (RX) unit connects to your display (TV, monitor, or projector) via another short HDMI cable. It converts the optical signal back into an electrical HDMI signal.
Key features
Long-distance transmission: Fiber optic extenders are ideal for applications requiring distances beyond the 15-meter limit of standard copper HDMI cables. Depending on the type of fiber used (single-mode or multi-mode), transmission can reach up to 20 km or more.
Uncompressed signal: Many models support uncompressed transmission, ensuring a clear image with zero latency and no signal loss, even at high resolutions like 4K and 8K.
Immunity to interference: Because fiber optic cables transmit signals with light, they are immune to electromagnetic and radio frequency interference (EMI/RFI). This makes them a reliable choice for installations near heavy machinery or electrical lines.
Support for additional signals: Many fiber extenders support the simultaneous transmission of other signals, including:
KVM (Keyboard, Video, Mouse): For controlling a computer remotely.
Bi-directional IR (infrared): Allows you to use your remote control to manage the source device from the display's location.
RS-232: A serial control signal for connecting peripherals like touchscreens.
Durable and flexible: Fiber optic cables are lighter, thinner, and more durable than bulky copper HDMI cables, making them easier to install, especially when routing through walls or ceilings.
supports resolutions up to 4K@60Hz and extends signals up to 300m over a duplex OM3 multi-mode fiber cable. It also supports 2-way IR and RS-232 control.
