Yes indeed, Jon makes a good point which I should've mentioned in my response as well (as I have been down this road).
If you are fortunate enough to have input with regard to cabling consider specifying fiber optic cables which comply with IEC 794-2 with inherent mechanical protection are considered less likely to break.

IEC 60825-2 is specifically for Optical Fiber Communications Systems (OFCS) and requires the consideration of fiber breaks exposing humans to the laser energy contained within. 60825-2 is referenced in 60825-1 and must be considered for OFCS. Additionally, you need to consider where the fiber goes as a break might occur downstream and expose not only direct users of the equipment.
