Use caution with this approach. 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.

Do the acid test type question ...
During normal use, what are you exposing the end user to?
For instance, with a laser pointer using a Class IIIb
laser that emits unprotected from the pointer, the
pointer is Class IIIb.
If instead, you are using a Class IIIb laser for fiber optic
communication and the entire beam is contained within
the fiber, no lasing is emitted from the product during
normal operation and/or service or maintainance, then
you *could* declare the telco product as Class I.
