OC-3/OC-12/OC-48 SFP low-speed SFP test procedure
Important!
OUT 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.

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.
........................................................................................................................................................................................................................
Remove the optical fiber jumper from the OLIU (at the LGX).

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.
When reference is made to optical fiber loopback connections to IN and
