Hi Doug,

During normal use the operator could be exposed to Class I. Service
personnel and installation would require potential exposure to Class
IIIb. Should the operators manual make reference to this. Also, wouldn't
you have to warn the operator and service personnel with text in the
manual and warning signs in the IIIb compartment of the system ?

Thank you,

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.
