Cisco GS7000 Installation And Operation Manual page 203

WARNING:
Laser transmitters when disconnected from their optical fiber path emit
invisible laser radiation, which is harmful to the human eye. If viewed at
close range, the radiation may be of sufficient power to cause
instantaneous damage to the retina of the eye. Only trained service
personnel using proper safety precautions and equipment such as
protective eyewear should disconnect and service the laser transmitter
equipment.
To Connect the Long-haul Fiber
1. Insert the fiber-optic start-head to the optical adapter.
2. Route fiber on the fiber tray of GS7000 GainMaker Node.
3. Connect the fiber-optic end-head to the receive bore of the OPM module
installed on the Receiver of the Prisma II platform.
4. The receiver OPM module requires LC connector, conversion maybe needed.
5. Clean the LC connector's fiber-optic end-faces.
See the following Tip for a pointer to a fiber-optic inspection and cleaning white
paper.
