Fiber is increasingly used for HDMI signal distribution. Not only does optical cable extend signal transmission distances, it also supports the bandwidth required for native, uncompressed 4K and 8K HDMI.
This article explores several popular fiber-based technologies used for HDMI.
Fiber-based HDMI cables, such as the TechLogix MOFO™ line, leverage a true fiber core to extend HDMI up to 50m (165 feet). Pre-terminated HDMI connectors accommodate installations in seconds and the optical construction provides complete immunity to RF, EM and electrical interference.
MOFO™ cables are built with four strands of re-terminable multimode fiber allowing cable runs to be upgraded and re-purposed in the future. The fiber core can be spliced and re-terminated with standard fiber optic connectors and tools.
The real-world application for re-purposing a fiber-based HDMI cable is the rapid expansion of AV over IP and streaming media. A MOFO™ cable used for HDMI today can be re-terminated for internet or other audio/video formats tomorrow.

HDMI over fiber extenders leverage standard single mode or multimode fiber to transmit audio, video and associated signals (such as control and network depending on the extender model). Basically, they are like twisted pair extenders that rely on optical fiber instead of copper.
The advantages of HDMI over fiber extenders include:
The disadvantages of HDMI over fiber extenders is the requirement of power at each end of the cable (though some extenders are powered from a display USB connection) and a higher price point.
For example, a fiber-based MOFO™ cable costs as little as $120 whereas a pair of HDMI over fiber extenders costs upwards of $425 or more.
