That level of complexity and precision is not needed for distributing daylight.
But that’s my point. The data thing isn’t relevant. It’s just transmitting light. The fact it can transmit data doesn’t means that’s what it’s for. It just transmits light of any intensity.
It’s a lot easier to just run some cables than install specialty ducts though. It doesn’t need as much space and you also don’t need to worry about being in straight lines. You just run the cable wherever you want and the light ends up there. Fiber optic cables effectively are just tubes with mirrors, except they dynamically adjust to whatever shape they’re in. If you’ve got a short path to the outside, sure, do the duct, although you might as well just do a window. If it’s to the interior of a building, especially if it’s already constructed, fiber optic cables are the only reasonable option.
