You've misunderstood the goal.

The intent is not to protect the fiber, but to make it easier for the 
field tech installing new service in a neat way through finished 
construction and concealled raceways, without cutting sheetrock or 
stapling exposed cabling across walls.

Trying to prevent the next "bad fiber install" set of pictures.

U.S. NEC does not require any mechanical protection for fiber cables.  You 
can run "bare" fiber cables through most residential spaces (with a few 
exceptions for jacket material, i.e. direct burial cable not allowed 
inside habital spaces).  Building codes may vary in other countries.

On the other hand, do some searches for "bad fiber install" for many 
examples of fiber installers stapling fiber around the outside of houses 
or zip-tied to gas pipes.
