LIGHT-LINK HDMI CABLE BY SEWELL, 100 FT 4K @ 60HZ 4:4:4 HDMI IN SOUTH AFRICA

Extend Full HDMI 2.0 Signal at 100 ft Full HDCP 1.4/2.2 Support 18Gbps Bandwidth 4K @ 60Hz 4:4:4 Compatible with ARC and CEC This amazing feat of technical wizardry is accomplished in two locations: the cable heads and the cable itself. In the cable head, there is a normal HDMI connector that plugs into your HDMI device. That HDMI signal is then processed into light by the built-in converter and sent out to the other cable head. The other cable head receives this signal and converts it back to HDMI. It then is sent through the normal HDMI connector to your display. Inside the cable itself, there are two cables: a fiber cable and copper cable. The copper cable is used for hot plug detection (so the source and display devices know when both ends are plugged in) and not used for any data transmission. The fiber cable is essentially that, a bundle of fibers that transmit light. The light travels down these 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 can travel incredible distances and not lose any quality.
