Why Is Glass Transparent?. It might seem silly since we encounter glass every day and you are reading this through a layer of glass right now.

The term "infrared" covers wavelengths from thousands of nanometers (think body heat) to about 700nm, which is just below visible red. The light used to transmit data in many devices via fiber optics or free-space optics, as Nickel2 pointed out, work up in the nearly visible range around 710nm to 1100nm. So yeah, IR easily passes through glass.

That's well done. Now here`s an even more fun question: Why does glass partially reflect some small amount of photons? (check out Feynman`s little book "QED: The Strange Theory of Light and Matter" for the answer. It`s a great down-to-earth explanation of the overall behavior of light).

If infra red did not pass through glass, those telecoms people have made a dreadful mistake choosing the stuff for fiber-optic transmission systems.

uh infrared cant pass through glass either and its less energetic than visible and much less energetic then ultraviolet.
