The Light-Link is an "HDMI over Fiber" cable that sends the video information through optical fiber. Because it uses fiber, it can send the signal instantly with no perceptible latency at longer distances than regular copper HDMI cables.

How it Works

The converters inside the cable heads convert incoming electrical signal into optical on one end, and back into electrical on the other end. The Light-Link is composed of fiber cables and copper cables. The copper cables are used for non-video information such as hot plug detection, grounding, and +5v power. The fiber strands carry all the video information.

The light travels down the fibers using internal reflection, which allows the light to bounce off the cable walls similar to a bobsled. Light travels extremely fast (186,000 miles a second) so the signal arrives almost instantly without losing any quality.  

Better than copper

According to "The longest HDMI cable runs seen to date have been achieved using fiber-optic cable, which is far less susceptible to attenuation and interference than copper. Electrically it is similar to an active cable or Cat 5/6 solution, the principal difference being the higher-quality optical cabling between the transmit and receive connectors. HDMI over fiber is a highly robust solution, effective in cable runs up to 100 meters or more."

Easier than any HDMI extender

Since the optical converters are housed inside the heads of the cable, there is no need for any external repeaters. This also means that there is no need for extra power adapters or patch cables.

The Light-Link eliminates possible points of failure. In a typical HDMI extender setup with baluns you have a total of eight connections:

  • x4 HDMI connections - video source to sender balun and receiver balun to display.
  • x2 RJ45 connections - transmitter balun to receiver balun.
  • x2 power connections - from baluns to power outlets.

That's eight possible things that can get unplugged, plugged in the wrong way, or become defective. With the Light-Link you only have one cable that can be easily verified end to end. Troubleshooting is incredibly easy compared to any other setup.

Fiber Optic HDMI Cable

Using a 50 foot Fiber Optic HDMI Cable. Pretty expensive but if you compare it to the Monster cables out there maybe not so much. Picture is clear as the main TV. I would definately recommend this product

I prefered the Pro version but these work well.

I like the version that I could add power to.
These are fully 4k and work really well.
Only time will tell how they last in the Audio visual industry. Local stagehands can be tough on these types of cables.
I am happy with the pro version I purchase a year ago.

Replacing cat 6 transmitter/receiver with fiber optic cables

In LDS meeting house application two cat 6 runs were next to each other, one with an output from a 4 port HDMI matrix and other from a camera mounted in back of chapel. Both runs terminate into a patch panel that goes to a Extron system that uses all shielded cabling. We were experiencing distortion from the camera. Replaced both runs with Sewell fiber optic HDMI cables and it solved the issue. I think like these cables better than the shielded cat 6 cables.

Fiber optic HDMI

I installed a 100’ HDMI and have been very happy with it. Before this I have been using HDMI over cat 6 but the adapter needed to be power cycled a couple times a week
