Unlisted OSP is limited to how many meters inside a building?

Unlisted OSP inside a building is restricted because those components aren’t specifically rated for indoor use, so the interior portion must be kept short to stay within listed and tested configurations. The standard maximum length for this unlisted interior run is 15 meters, ensuring most of the path uses components that are approved for indoor installation and compatible with firestop and building codes. If more indoor length is needed, you’d switch to listed indoor-rated components or route through a listed pathway. That’s why 15 meters is the correct limit.
