4K HDMI Fiber KVM Extender with Audio, IR, Serial, USB 2.0 (up to 10KM) (Single-Mode)

HDMI Fiber KVM Extender, FXMS-M033, consists of a Transmitter (Host) and a Receiver (Device) unit that allows you to extend HDMI/ Audio/ USB 2.0/ IR/ RS-232 signals over SC S-M Fiber Optic Cabling. It transmits 4K HDMI video up to 10 kilometers (32800 ft) through a single SC Duplex Single-Mode fiber cable in a point to point configuration.This 4K Fiber KVM Extender supports most popular signal resolutions up to 4K 30Hz at (4:4:4) color sampling and is ideal for the most demanding applications.


Comprising a compact Transmitter and Receiver pair (models FXMS-033P & FXMS-033S respectively), the FXMS-M033 4K HDMI Fiber KVM Extender can be installed in minutes and requires no special programming. Using fiber optical cable provides a lot of advantages over traditional copper-based extension methods, involving thinner and lighter cables, immunity to RF and magnetic interference, and much longer extension distances up to 10KM. That means the benefits of the Fiber KVM Extender like EMI-free, long-distance transmission, reliability, and efficiency far outweigh its higher cost. It is great for uses in electronically “noisy” environments such as factory shop floors or medical applications.

Exclusive Economic Solution for Aviation and Marine Application Supports 2048 x 2048 Resolution

HDMI Fiber KVM Extender, FXMS-M033, supports a unique resolution of 2048 x 2048 for air traffic control and marine radar application. Instead of purchasing an expensive 2048 x 2048 radar display, users can get a normal screen and set Rextron Fiber Extender between the monitor and the video source to accurately display the 2048 x 2048 resolution.

The 10KM 4K HDMI Fiber KVM Extender with speaker and MIC audio functions provides comprehensive management of EDID (Extended Display Identification Data) to ensure that the computer is displayed at the optimal resolution and format without any compatibility issue. With the serial extension function it enables users to control RS-232 devices remotely, mostly for Projectors, Central Control System, POS system, AV Switches, Printers, etc. A simple OSD menu feature is to show up and setup its baud rate speed information with the range from 1200 to 115200bps.

USB 2.0 extension function enables users to transmit USB 2.0 signals over a fiber optical cable with downward compatibility eliminating the USB distance limitation of 5 meters and supports USB peripherals sharing on a pure Plug & Play hardware design basis. Dedicated USB 2.0 ports design on both front and rear panels are ideal for both long-term and temporary USB peripherals access, and allow users to attach or detach USB devices with ease.

The HDMI Fiber KVM Extender with Windows, Linux, Chrome and MAC OS supported is perfect for data centers, offices, control rooms, airports, server rooms or the factories applications. Rextron also offers a series of DVI Fiber KVM Extenders, and DisplayPort Fiber KVM Extenders to meet users’ application need. An interoperable design for various interfaces of HDMI, DisplayPort and DVI, provides great flexibility to satisfy different installation requirements at customers’ environment.
