Light-Link DisplayPort Cable
The Light-Link DisplayPort is a "DisplayPort 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 DisplayPort 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
The maximum recommended length of regular DisplayPort Cables is about 6-10 ft. for full functionality depending on the quality of the cable. DisplayPort over fiber breaks that barrier allowing extension up to 300ft.
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 DisplayPort 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.
