DIGITUS HDMI Fiber Extender Set - 4K/60Hz, 40 km/300m čierny

The HDMI Fiber IP Extender Set Digitus 4K/60Hz Transmitter Receiver enables transmission of HDMI signals in UHD (4K/60Hz, 3840 x 2160) over fiber optic cable for point-to-point installations. The kit includes a transmitter (TX) and receiver (RX) designed for professional AV environments and supports both singlemode and multimode fiber connections when used with compatible SFP modules.

Advantages

This extender set supports long-distance transmission—singlemode up to 40 km and multimode up to 300 m—and preserves high picture quality with low latency (approx. 80–140 ms). It can use existing 1G network infrastructure or 1G switches for flexible signal routing and allows cascading to extend range further. The units are compatible with LC and SC SFP modules and both fiber cable types. Additional features include an HDMI loop-out on the transmitter for a local monitor, a 3.5 mm stereo audio output for separate audio transmission, and an IR interface to control the source from the display end.

Suitable for

• Conference rooms and meeting spaces
• Control centers and monitoring stations
• Digital signage and retail displays
• Broadcast studios and production facilities

How to use

Connect the HDMI source to the transmitter HDMI IN and, if required, connect a local monitor to the transmitter HDMI loop-out. Insert compatible SFP modules into the transmitter and receiver and connect them with the appropriate singlemode or multimode fiber cable. Power both units using their 5 V supplies. Use a 1G switch or direct fiber link for point-to-point transmission; cascade additional extenders via 1G network switches to extend distance. The receiver outputs the HDMI signal to the display and can send remote IR commands back to the source through the IR interface.

Recommendations

For guaranteed performance at maximum distances, use recommended SFP modules (DN-81002 for singlemode, DN-81000 for multimode) and high-quality fiber cabling. When deploying in larger AV networks, plan switch capacity and cascading points to maintain 1G throughput and minimize latency.
