OC-48 low-speed testing

OC-48 low-speed testing procedure
Perform the following steps for all Alcatel-Lucent 1665 DMXtend shelf function unit or
growth slots containing OC-48 (LNW31) OLIU circuit packs.
Note:
on the OLIU, make the connections at the LGX equipment in order to verify correct
installation and labeling of the fibers.
LBOs are installed on the OLIU faceplate IN port.
........................................................................................................................................................................................................................
1
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.
........................................................................................................................................................................................................................
2
Insert a 15-dB LC-type LBO into the top IN connector of the OC-48 OLIU. See
C, "Installing fiber connectors and
Connect the fibers labeled IN and OUT from the LGX to the OLIU.
........................................................................................................................................................................................................................
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
When reference is made to optical fiber loopback connections to IN and OUT
The FAULT LED on the OC-48 OLIU will begin flashing and the MN and NE
LBOs".
