14. Using Table A and the measured received power, determine the correct build-
out value.
15. Clean the lightguide buildout and the IN connector of the RCVR circuit pack
with canned air or nontoxic gas.
Reference: DLP-510
16. Install the buildout to the IN connector on the RCVR circuit pack.
Reference: DLP-512 and DLP-519
17. Locate the receive fiber for line 1W.
18. Remove the protector cap (if equipped) from the end of the receive fiber.
19. Clean the receive optical fiber and the buildout with canned air or nontoxic gas
(buildout is installed at the IN connector on the RCVR circuit pack).
Reference: DLP-510
20. Connect the receive fiber to the buildout (inserted at the IN connector on the
RCVR circuit pack).
21. Repeat Steps 3 through 20 for line 1E.
NOTE:
At this point, the TRMTR and RCVR circuit packs should be connected to their
respective lines.
Table A - Optical Line Buildout Values (Notes 1 and 2)
Measured Received Power in dBm Use Optical Buildout
−2.0 to −4.9 15 dB
−5.0 to −9.9 10 dB
−10.0 to −14.9 5db
−15.0 to −25.5 0 dB
−25.5 dBm or less Optical loss out of range.
Contact line engineering.
Notes:
1. A 20 dB optical line buildout is typically used for optical loopback testing.
2. The fiber must also meet the outside plant loss as specified in the optical
line loss budget of Section 10 of this manual.
