USB 3.0 over Fiber

In Stock

"Ordering process was easy and product arrived faster than I had expected. Thanks."


The Light-Link is a 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.

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.

An optional micro USB port is provided in the event your USB devices require additional power.

Fiber Optic Cable

Light travels down the fibers using internal reflection, which allows the light to bounce off the cable walls similar to a bobsled. The speed of light is extremely fast (186,000 miles/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.
