OC-192 (low-speed) testing

OC-192 low-speed testing procedure
Perform the following steps for all Alcatel-Lucent 1665 DMX shelf Function unit or
Growth slots containing OC-192 (LNW603) OLIU.
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
Identify the function groups that contain an OC-192 OLIU circuit pack and fully insert the
OLIU into the shelf.
Requirement:
OLIU.
........................................................................................................................................................................................................................
2
Insert a 15-dB LC-type LBO into the IN connector of the OC-192 OLIU. See
"Installing fiber connectors and
Connect the fibers labeled IN and OUT from the LGX to the OLIU (Port 1).
........................................................................................................................................................................................................................
3
Connect the IN connector to the OUT connector (at the LGX) of the OC-192 OLIU, using
an optical fiber jumper cable. See
instructions.
Requirement: The FAULT LED on the OC-192 OLIU will begin flashing and the MN
and NE 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.
........................................................................................................................................................................................................................
4
Remove the optical fiber jumper from the OC-192 OLIU (at the LGX).

NOTICE
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.
When reference is made to optical fiber loopback connections to IN and OUT
After a few moments, the ACTIVE LED should be lit on the OC-192
LBOs".
