OC-48 PTM equipped low-speed testing procedure
Perform the following steps for all Alcatel-Lucent 1665 DMXtend shelf function unit or
growth slots containing LNW62, LNW55, LNW402 (OC-48) OLIU circuit packs.
Note:
LNW84 be installed in the main slots to operate in a Alcatel-Lucent 1665 DMXtend
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.

Beginning from the top (G) of the Alcatel-Lucent 1665 DMXtend shelf, locate the first
function unit slot that contains an OC-48 OLIU circuit pack.
........................................................................................................................................................................................................................
Insert a 15-dB LC-type LBO into the top IN connector (port 1) of the OC-48 OLIU. See

Appendix C, "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-48
OLIU, using an optical fiber jumper cable. See
fiber cleaning instructions.
Result:
LEDs should be lit on the SYSCTL circuit pack.
After approximately 20 seconds the flashing FAULT LED should extinguish on the
OC-48 OLIU and the FAULT, MJ and NE LEDs should be lit on the SYSCTL circuit
pack.

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, see
The LNW62, LNW55 and LNW402 circuit packs require the LNW141 or
