I’m no engineer, but this is a glass tube, not a glass sheet. I thing the amount of bending it does without breaking will be very small.

  fiber optic strands are glass tubes and they bend.

    Fiber optic strands are glass rods (solid interior) instead of tubes (hollow cylinder). The two shapes have different strength properties per unit mass [1, 2].

      Traditionally, yes. Hollow air core fibre does exist and seems to be touted as the next big thing though. https://www.optcore.net/hollow-core-fiber-introduction/#h-what-is-hollow-core-fiber https://www.optcore.net/hollow-core-fiber-introduction/#h-wh...

        Current implementations break from simple vibrations such as a bus driving down the road and shaking the ducts the fibre is in. Lots of work required still. Crazy expensive and crazy fragile.

    Pretty much every solid material gets vastly more bendable when it's very thin. (From vague memory, stiffness is proportional to the cube of the thickness.)
