DLP-512: Detailed Level Procedure 365-575-102
Page 4 of 14 Issue 8.0, July 2002
NOTE:
Be sure to (a) connect the RCVR fiber to the power meter, (b) set the optical
power meter for the wavelength of the light to be measured, e.g., 1300nm.
13. While considering the application (Table A), and the measured receive power
level from Step 12, choose the appropriate LBO from Table C.
Table C – Optical Line Buildouts
14. Align the buildout with the slot in the buildout block, push in, and rotate clock-
wise until locked into position. Refer to the appropriate Figures (3, 4, or 5) for
the specific buildout type.
15. STOP! YOU HAVE COMPLETED THIS PROCEDURE.
Low Speed Fiber Installation
16.
NOTE:
This procedure is used to select the proper value of LBO to be used on the
faceplate of the LAA5/LAA10/T939A (OUT) jack.
The LAA5 supports span lengths up to 2000 feet, when using MM fiber. The
LAA10 supports span lengths from 0 to 51 km, when using SM fiber. Also, the
T939A supports span lengths from 0 to 51 km, when using SM fiber.
Low speed fibers connect (either directly or through an intermediate LGX) to
circuit packs within the Low Speed Shelf. Connectors are located on the
faceplate of the LAA5, LAA10, or T939A circuit packs. Connection is made to
a removable Optical Line Build-Out (LBO). Only 0dB LBOs are used in the
RCV (IN) port, and attenuating LBOs must be used in the TRMT (OUT) port.
