The Light-Link is a USB 3.1 Gen 1 (formerly USB 3.0) Fiber Optic Cable. Because it uses fiber, it can send the signal instantly with no perceptible latency at much longer distances than regular USB extenders.

Note: This cable is compatible with devices that are USB 2.0 as well as USB 3.1 Gen 1 (Formerly USB 3.0), but it has to be plugged into a USB 3.1 Gen 1/USB 3.0 port in order to function! The supplemental power cable will be needed for USB devices that aren't low power.

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 two fiber cables and two copper cables. The copper cables are used for non-data information such as +5v power for USB devices. The fiber strands carry all the data 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.

Eliminates possible points of failure

In a typical long distance USB extension setup, you have many potential points of failure (source to sender, receiver to device, an RJ45 cable in between, and two power adapters for the baluns). The Light-Link extends the signal with zero latency and without having to worry about baluns or power adapters.

Optional Extra power

The Light-Link USB features a micro USB-B port to provide Auxiliary power for devices that require a little more power than usual. (Not required for most devices)
