Answer 1

Tech manuals, actually.

And you're going to have some cross-over now from fiber optics. Cabling passes through the plenum areas of buildings, and it comes into contact with heating and ventilation equipment. Industry compatibility falls mostly on the side of the fiber techs, but HVAC is moving in the direction of compatibility as well.
