HDMI (High Definition Media Interface) cables are the interface between any audio/video source. They have become, over time, the standard for transmitting high definition audio & video signals. With today’s constantly developing technology, the good old familiar copper HDMI cable, is struggling to support true 4K signal over 50 feet.
HDMI Fiber Optic Cable
That is where HDMI fiber optic cable comes to play. This new technology offers dramatically faster speeds than the traditional copper HDMI cable. HDMI fiber optic cable allows for extra-long transition distance (20 miles without need for a repeater). It is a small cable (0.125mm/0.005” with cladding) that is also lighter in weight and now also offers easy cable field termination.
RF over Fiber Optics?
Radio frequency (RF) does not transmit over fiber optics, only light. For this reason, the HDMI fiber optic cable is equipped with connectors that are enabled with a chip. This chip converts the RF so it can travel over the fiber optic cable. This way audio/video users can enjoy true 4K with longer cable distances.
Self Sustaining Connectors
In the past, HDMI over fiber optics needed additional power supply to the cable. That made installation complex. New innovations now allow for self-sustaining cables. The connectors now have all that they need built into them, making them plug-and-play ready.
Still to be Developed
As it stands, in 2017 what prevent fiber optics from replacing copper wires are a few factors. To start with, connectors at each end of the cable add significant cost to an HDMI fiber optic cable. At the moment, two-way communication is not available. Light only travels in one direction. To achieve two-way communication another set of HDMI fiber optic cable must be installed (ultimately – double the cost).
HDMI fiber optic cable has over gone tremendous changes and thanks to its innovations and new technological breakthroughs it now offers great advantages.
