WARNING
The ASA 312’s optical Transmit output is produced by a Class 1 laser device.
You should never, under any circumstances, look into an unterminated fiber.
Always turn the Laser off when a fiber is unterminated. After connecting the
fiber, turn the Laser on.
Connect the fiber optic cable to the input of the optical attenuator so that you
have a direct fiber connection from the ASA 312’s
OC-1/3/12 TX
port to the
optical attenuator’s input port.
5. Connect one end of a second fiber optic cable from the optical attenuator’s
output port to the optical power meter’s input port.
6. Proceed to the next section to enter the optical power for Range 2.
