What it does
The run from the PC to the ceiling
A projector at the back of a bay is thirty feet of cable from the PC. The cable decides whether the picture arrives intact.
Fiber, not copper
Active optical transmission, in Carl’s words slim, flexible and interference-free over the length a ceiling run needs.
HDMI 2.1
8K at 60 Hz, per Carl’s — more than any projector in this catalogue draws, which is the point: the cable is never the limit.
Two lengths, one direction
32.8 or 49.2 ft. The ends are not interchangeable; mark which goes to the PC before it runs through a ceiling.
