OC-12 low-speed testing

OC-12 low-speed LNW49 and LNW55 PTM testing procedure
Perform the following steps for all Alcatel-Lucent 1850 TSS-60 shelf function unit or
growth slots containing OC-12 (LNW49 or LNW55) OLIU circuit packs...
Note:
main slots to operate in a Alcatel-Lucent 1850 TSS-60 shelf.
Note:
on the OLIU, make the connections at the LGX equipment in order to verify correct
installation and labeling of the fibers.
Note:
associated fibers, then move PTMs to ports that are fibered. LBOs are installed on the
OLIU faceplate IN port.

1
Beginning from the top (G) of the Alcatel-Lucent 1850 TSS-60 shelf, locate the first
function unit slot that contains an OC-12 OLIU circuit pack.
........................................................................................................................................................................................................................
2
Insert a 15-dB LC-type LBO into the top IN connector (port 1) of the OC-12 OLIU. Refer
to Appendix D, "Installing fiber connectors and
Connect the fibers labeled IN and OUT from the LGX to the OLIU (port 1).

3
Connect the Port 1 IN connector to the Port 1 OUT connector (at the LGX) of the OC-12
OLIU, using an optical fiber jumper cable. Refer to

CAUTION
Laser Safety
When connecting fiber loops between the IN and OUT ports on optical circuit
packs, always connect to the IN port first and then the OUT port. This will
prevent any optical radiation from being present at the fiber end.For more
detailed information and safety precautions, refer to
The LNW55 circuit packs require the LNW141 or LNW84 installed in the
