OC-3/OC-12/OC-48 SFP low-speed SFP test procedure
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 LNW37/LNW45 OC-3, LNW49 OC-12,
LNW62/LNW402 OC-48 or LNW55 12-port multi-rate OLIU circuit pack.
........................................................................................................................................................................................................................
2
Insert a 15-dB LC-type LBO into the top IN connector (Port 1) of the first SFP equipped.
See Appendix B, "Installing fiber connectors and
Connect the fibers labeled IN and OUT from the LGX to the OLIU (Port 1).

Connect the Port 1 IN connector to the Port 1 OUT connector (at the LGX) of the OC-3,
OC-12 or OC-48 OLIU using an optical fiber jumper cable. See

Requirement: The FAULT LED on the 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 OLIU
and the FAULT, MJ and NE LEDs should be lit on the SYSCTL circuit pack.

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
If inserting an SFP, see
for proper fiber cleaning instructions.
