HDMI over a single FIBER? E-Link Detachable HDMI 2.0 over Multimode Adapters

Published at : 23 Dec 2025

Today I'm testing an adapter which lets me convert HDMI 2.0 to run over off-the-shelf OM3 and OM4 Multimode Fiber! The same stuff that's super easy and cheap to buy online, made to length, fish through small places in your walls, and that can be re-used for all kinds of high speed networking stuff.
