So I had to order a 50ft HDMI fiber optic cable 5 times to get 2 of these that worked. All 5 fiber optic HDMI cables from DTECH had kinks caused by cable coiling at the factory. Two cables were routed through a floor cut-out for one of our conference rooms with two LED monitors. The installer ignored the kink, not knowing it was fiber optic cable. After installing the HDMI cables, they didn't work, so we let him pull the cables. The installer showed us the cable and kinks after pulling it out. We ordered two more thinking it was a coincidence. Who twists so much fiber optic cable. The other two have arrived. One was just as twisted. The other had a slight kink. One worked and one didn't. We ordered the 5th which had a slight crease but worked. After all this we missed the return window on the first two cables but were able to return the 3rd. So we lost over $250. Thanks to the seller/manufacturer.
