The Thunderbolt Optical Cable from Optical Cables by Corning is 18' long and offers two independent channels that deliver 10 Gb/s of data each. It bonds the two channels to deliver 20 Gb/s speeds over long distances. With Thunderbolt support, you may daisy chain your system with up to six Thunderbolt devices at the same time. This cable is built with a zero-bend radius, which lets it be bent, squeezed, and tangled. In addition, it is thin, lightweight, and durable as well.
