LBO Selection and
Replacement
Procedure
This procedure is used to select the proper value of Line Build Out to be used on
the faceplate of the OA IN jack based on received optical power. The Optical LBO
selection procedure is to be used in conjunction with the Receive OA Connection
Procedures. Read and understand the procedure to become familiar with it.
Step Action
1 At the local node and at the far end node, disable APSD.
2 Measure, and record for office records, the received optical power from
the far end. Be sure to set the optical power meter for the wavelength of
the light (1550nm) to be measured.
3 Remove the 0 dB line buildout from the IN connector on the faceplate of
the OA. To remove, press the tab on the top of the buildout with a small
blunt tool, and rotate the buildout counterclockwise slightly. Slide the
buildout out along the angle it is installed in the faceplate.
4 Install the chosen buildout. To install, remove the protective covers from
the chosen buildout. With the tab facing up towards you, slide the
buildout into the faceplate of the OA over the fiber end in the faceplate at
the angle of the connector block in the faceplate. The buildout will be fully
inserted when the tab is very slightly rotated counterclockwise. To lock
the buildout in position, rotate the buildout clockwise until a small click is
heard. Check that the buildout is locked in position by lightly tugging at it.
