Mark, The ANSI spec (in Z136.2) provides specific info for OFCS (Optical Fiber Communications Systems). This specific information relates to, among other things, installation location/product accessibility and personnel exposure/training and marking. ANSI developed 'Service Group'(SG) classifications, with the previously mentioned items lumped-in with the laser Class. For the most part the SG classification tracks the laser Class - Class I = SG1 . . Class 3b = SG3b.
Are the installation/service personnel also the end-user/operator? Is there a possibility for the end-user, at any time, access the 3b without much difficulty? If yes, the manual would indeed be an additional place for a statement relating to 3b.. ANSI specifies that in SG3b areas (even if it's inside the product itself) must be marked with a DANGER statement see the spec for details). Also worth noting is that those who will be exposed to Class IIIb - installation or service personnel (which puts the product in the SG3b category) as you noted have to be trained. "Only authorized trained personnel shall be permitted to install or perform service on SG3a, SG3b, or SG4 OFCS." In my opinion, whether or not the installers/service/end-user is trained or not (sometimes the trained are worse because they tend to be over-confident and throw caution to the wind) it's worth marking the areas on/in the product as well as putting references in the manual.

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 ?

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. - Doug McKean ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
