Step Action
3 Momentarily remove then reconnect the fiber on the SONET/SDH system
output jack.
Requirement: The optical power meter shows a momentary loss of
optical power. (Power drops at least 25 dB on the meter.)
4 Select an optical LBO of the correct type that will attenuate the measured
signal to provide a signal into the OTU/OTPM of between –12 and –22
dB.
If an attenuated LBO is needed, install it as follows:
a. Remove the 0-dB LBO in the faceplate of the OTU/OTPM. To
remove, press the tab on the top of the buildout with a small blunt
tool, and rotate the buildout counterclockwise slightly. Slide the
LBO out along the angle it is installed in the faceplate.
b. Install the chosen LBO. To install, remove the protective cover.
With the tab facing up towards you, slide the LBO into the
faceplate of the OTU/OTPM over the fiber end in the faceplate at
the angle of the connector block in the faceplate. To lock the LBO
in position, rotate the LBO clockwise until a small click is heard.
Check that the LBO is locked by lightly tugging on it.
5 At the OTU/OTPM, clean and connect the measured jumper to the IN
jack.
Requirement: The OTU/OTPM FAULT LED shall stop flashing within
1 minute. [Loss of Signal (LOS) alarm extinguishes.]
