At both ends of the optical span, ensure that only the dual LC adapter is installed on the
OLIU (no LBO).
Note:
configurations, optical fibers extend in two different directions to make up the ring. At
each shelf (node) in the ring, the M1 OLIU will connect to the M2 OLIU in one
adjacent node, and the M2 OLIU will connect to the M1 OLIU in the other adjacent
node. Likewise, when the Alcatel-Lucent 1665 DMXtend is interfacing with other
equipment at low-speeds (OC-3, OC-12 or OC-48) using 0x1 protection, the Function
Group slot (D, or G) 1 will connect to Main 2 on whatever shelf the Alcatel-Lucent
1665 DMXtend is being connected to. The Function Group slot (D, or G) 2 will
connect to Main 1.

At each end of the optical span, connect the optical fiber transmit cables to the OLIU OUT
connectors.

15
At each end of the optical span, measure the optical power of the optical fiber receive
cables using an optical power meter.

Determine the LBO value required based on the received optical power measurement. See
the following table and attenuate appropriately.
