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.

Light-Link Fiber Optic HDMI Cable

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

Light-Link Fiber Optic HDMI Cable - Great Product!

Thought I would have to redo my whole AV build because of a cable length issue, but happen to see an ad for the Light-Link Fiber Optic HDMI cable and Sewell saved the day. Great picture and audio and no external power needed, truly a great product. Sewell Saved the day!

Amazing Product... Highly Recommended!!!

Pros: What an amazing product. I was really frustrated when I learned of the 6' 4K limit on the Display Port connection. My 4K monitors are across the room and a 6' cable would do nothing for me. I looked at several websites for solutions and the cheapest cable that I could find was over $250 to carry the signal to the other side of the room. Since I had five connections to make, this was going to cost $1,400 with tax and shipping. Then I discovered the Sewell Direct website. The Light-Link 40' HDMI cable was the perfect solution at a very reasonable cost. It works perfectly and the 4K pictures and videos at 60hz are spectacular. I highly recommend these cables and the Sewell Direct company. The product is superb and the customer service has been stellar!Cons: NoneOther:
