At both ends of the optical span, ensure that only the dual LC adapter is installed on the
OLIU (no LBO).
Note:
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 DMX is interfacing with another Alcatel-Lucent 1665 DMX at low-
speeds (OC-3, OC-12 or OC-48) using 0x1S1 and 0x1S2 protection, the Function
Group slot (A, B, C, D, or G) 1 will connect to Main 1 or Function/Growth slot 2 on
the shelf the Alcatel-Lucent 1665 DMX is being connected to. The Function Group
slot (A, B, C, D, or G) 2 will connect to Main 2 or Function/Growth slot 1.

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

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.
