Sewell Light-Link USB, USB 3.0 over Fiber
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. Note: The 50 and 100 ft versions of this cable are compatible with devices that are USB 2.0 as well as USB 3.0, but it has to be plugged into a USB 3.0 port in order to function! The 30 ft is currently only compatible with USB 3.0 devices. 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
