Purchased this cable.  Box is open but never unwrapped the cable.  Realized I bought the wrong thing and return window was passed. Absolutely new condition.  Please ask questions before bidding.

The Thunderbolt Optical Cable from Optical Cables by Corning is 33' 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.
