Remove power from the optical source before disconnecting optical fibers, if the
source is not a laser Class 1 product, or if the laser Class of the source is
unknown.
Never scan a fiber with an optical test set without verifying that all lightwave
sources on the fiber are turned off or that the test set is specially approved for the
test.
When in doubt, verify that the optical source is switched off by measuring the
optical output with an optical power meter.
When fiber is disconnected from the COP or other optical component, always put
a protective cup on the optical connectors of the fiber and the optical component.
Laser warning labels
The laser warning labels indicate the laser class and hazard level of laser radiation.
The Stinger is classified as class 1/I unit. This means that, under normal operating
conditions, all energized laser transmitting components are terminated on optical
fibers that enclose the laser energy with the fiber sheath. Also, covers are in place
over the circuit pack shelves.
The labels shown below are used to identify systems that belong to laser class 1.
Figure D-2.
Handling optical fibers
Never look into the end of an optical fiber or connector when the optical source is
switched on. Always observe the laser warning instructions.
Routing and connecting
During installation, the optical connectors of the fibers and the Stinger circuit pack or
module must be equipped with a protective cap until they are coupled. The fibers
should by guided to the optical circuit pack or module using the special protective
spiral wrap of the pigtail.
