This fiber KVM extender provides reliable remote access to a single-monitor PC over duplex fiber cabling, supporting various extension distances using duplex LC multimode or single-mode SFP transceivers. It supports HDMI 1.4 video resolutions up to 4K at 30Hz (4:4:4) with EDID pass-through and HDCP 1.4 compliance. USB 2.0, IR, and serial signals are extended alongside video, with the serial port supporting eight selectable baud rates from 9600 to 115200bps. Front USB ports allow convenient device connections, while smart audio extension automatically switches from HDMI to analog audio when 3.5mm jacks are inserted. The unit operates with a wide DC 12-48V input range, requires no drivers or software, and is compatible with Windows, macOS, Linux, and Chrome OS. Fiber connections provide isolation from EMI and electrical noise.
Overview
The KVM Fiber Extender, IPXF-H430-SH550F/SH00KF, consists of a transmitter (computer) and a receiver (console) unit that extends 4K30 HDMI video, audio, USB 2.0, IR, and RS-232 signals over duplex multimode or single-mode fiber optic cabling. It supports transmission of 4K30 HDMI video to various extension distances using multimode or single-mode duplex LC SFP transceivers. The actual distance depends on the type of SFP transceivers and fiber cables used.

USB 2.0 Hub – Plug-and-Play Peripheral Sharing
The KVM Fiber Extender supports USB 2.0 expansion, with four USB 2.0 ports located on the front and rear of the receiver (RX) unit. These ports are ideal for both long-term and temporary connection of USB peripherals. The USB hub supports most popular operating systems, including Windows, macOS, Chrome OS, and Linux.
2-Way Audio
The extender supports bi-directional audio transmission, independently sending audio signals between the transmitter and receiver units. This 2-way audio feature is especially important for PA systems and emergency communication, enabling real-time notifications to the control center and facilitating remote communication and coordination.
Smart Audio Extension
The main audio extension channel can be intelligently distributed to either HDMI audio or the speaker/microphone (SPK/MIC) extension. The SPK/MIC extension has a higher priority than HDMI audio, and HDMI audio will be disabled whenever a SPK/MIC connection is detected.

IR Extension
The IR extension feature supports the full frequency IR range from 38 kHz to 56 kHz. The distance between the IR emitter and the IR port on the unit can be extended for flexible installation of IR control systems. (Up to 1.4 meters IR cable, sold separately.)
RS-232 Serial Extension with Selectable Baud Rate
![]() | The extender enables full-duplex RS-232 communication between the transmitter and receiver. It supports selectable baud rates from 9,600 to 115,200 bps, providing a cost-effective, hardware-based solution for remote access and control of RS-232 devices without software configuration. Ideal for use in digital signage, industrial and commercial automation, smart classrooms, and conference rooms. |
