Digitus DS-55348 HDMI Fiber KVM IP Extender Set 4K/60Hz Transmitter and Receiver Wired 40000 m

The Digitus DS-55348 HDMI Fiber KVM IP Extender Set 4K/60Hz Transmitter and Receiver Wired 40000 m is a professional-grade solution designed for high-resolution digital video signal transmission and remote device control over extreme distances. Utilizing fiber optic technology, this wired transmitter and receiver set ensures stable and secure delivery of uncompromised audio-visual content. It supports Ultra HD 4K at 60Hz resolution, making it well-suited for professional environments that demand precision, clarity, and reliability.

Advantages

This extender set delivers exceptional performance by allowing long-range signal transmission up to 40,000 meters over singlemode fiber or up to 300 meters over multimode fiber in a point-to-point setup. By leveraging IP network infrastructure and 1G network switches, the system supports scalable network topologies including point-to-multipoint configurations with up to 253 receiver units and cascading for virtually unlimited reach. Integrated KVM functionality on the receiver side allows operators to connect a keyboard and mouse to manage the remote source efficiently. Additional features such as an HDMI loop-out on the transmitter, 3.5 mm stereo audio support, RS232 pass-through, and robust mechanical protection against short circuits, overvoltage, and electrostatic discharge further enhance operational dependability in demanding professional deployments.

Suitable for

• Control rooms and security monitoring centers requiring remote computer management
• Large corporate conference rooms and auditoriums for high-definition presentations
• Data centers needing extended hardware management across separate server rooms
• Digital signage networks spanning large commercial buildings or campuses
• Industrial automation and broadcast environments requiring long-distance signal routing

This system may not be suitable for basic residential entertainment setups, casual home office environments, or applications lacking fiber optic infrastructure where standard copper HDMI cables or short-range wireless extenders would suffice. The latency of 80 to 140 ms may also not meet the strict real-time response requirements of competitive gaming or high-speed interactive professional applications.

Key specifications

• Transmitter and receiver wired set with metal housing
• Maximum transfer distance up to 40000 m over singlemode fiber, 300 m over multimode fiber
• Maximum digital resolution: Ultra HD 4K at 60Hz (3840 x 2160 pixels)
• HDMI 2.0 and HDCP 2.2 / 1.4 compatibility
• Maximum video bandwidth: 18 Gbps
• H.265 compression with 80-140 ms latency
• Transmitter connections: 1x HDMI input, 1x HDMI loop-out, 1x SFP output, 1x USB-A, 1x RS232, 1x 3.5 mm audio input, power supply
• Receiver connections: 1x HDMI output, 1x SFP input, 2x USB-A for keyboard and mouse, 1x 3.5 mm audio output
• Power consumption: 7.5 W per unit (TX and RX)

To set up the system, connect the video source to the transmitter unit using an HDMI cable and link the local display to the HDMI loop-out port if local monitoring is required. Insert compatible SFP modules into the SFP slots and connect the transmitter and receiver using the appropriate singlemode or multimode fiber optic cables. Connect your keyboard and mouse to the USB ports on the receiver unit and attach a display to the receiver's HDMI output. Power both units using the included external power supplies. Once the network link is established, the system will transmit the video, audio, and control signals automatically.

What to consider before purchase

• SFP modules and additional receiver units are sold separately and must be acquired based on your specific cabling requirements
• Ensure appropriate fiber optic cabling (singlemode or multimode) is already installed or planned between the source and display locations
• Verify that the network switches, if used for IP extension, meet 1G network infrastructure specifications
• Take into account the operational latency range of 80-140 ms for your specific application requirements

For optimal performance and longevity, ensure proper ventilation around the metal enclosures, operate the units within the specified temperature range of -10°C to 50°C, and use certified fiber optic cables and compatible SFP modules during installation.
