4K 4:4:4 60Hz 18Gbps HDMI HDCP 2.2 Bidirectional IR or RS-232 over OM3 Multi-Mode Fiber

WyreStorm’s first fiber-optical extender, ensuring perfect transmission of 18Gbps HDMI signals to 300m/984ft. The EXF-300-H2 is compatible with 2160p 4:4:4/60 or high frame rate HDR content with HDCP 2.2 encryption, and will send it via a 10G OM3 multi-mode cable without any effect from EM or RF interference along the way.

Having a physical form, copper cable causes attenuation and weakens a signal with every metre that it has to travel. Pixel-perfect transmission of HDMI content as light is now possible over optical fiber up to 300m/984ft.

The highest possible bandwidth that currently exists according to the HDMI 2.0 specification can be sent using the latest optical transmission technology.

HDR Content has recently enjoyed an up-shift in refresh rates after starting its life at 24Hz on UHD Blu-Ray discs. High frame-rate HDR is now available at 60Hz on certain discs and via games consoles like the Xbox One X.

Optical transmission is immune to EM and RF, meaning that electronically “noisy” environments such as industrial or retail premises have historically been difficult for copper as a medium. Using optical transmission over a multi-mode fiber core, the EXF-300-H2 ensures a solid, stable signal over nearly 1000ft.


  • Extends 18Gbps HDMI transmissions using multi-mode fiber up to 300m/984ft

  • HDCP 2.2 compliant
