Question

I found a convenient channel between floors where I can run fiber optic cable. Do I need to use riser-rated or plenum-rated cable?

Bruno's Answer

If the space is designed to circulate air between different areas of the building, then it requires plenum-rated cable. For other spaces, such as a wiring closet, riser-rated cable can normally be used. Consult with your local codes authorities just to be sure.
