LBOs

General
LBOs are fixed-value optical attenuators that mate into mounting blocks and provide a
specific connector interface (LC, ST, FC or SC-type) for external fiber connections. The
Alcatel-Lucent 1850 TSS-5 optical circuit packs are equipped with LC-type connector
ports designed for use with LC-type LBOs and fiber connectors. Dust caps should be
applied on all LBOs when not installed in connector ports.
LC-type connector port
The LC-type connector port will only accept LC-type LBOs for external fiber connection.

LC-type LBO
Alcatel-Lucent 1850 TSS-5 utilizes Alcatel-Lucent's state-of-the-art AllWave
ADVANTAGE™ Fiber Optic Attenuators. These attenuators reduce optical power from the
transmitter that can result in over-saturation of the receiver, have low reflection to meet
stringent system requirements, and are backward-compatible with existing transmission
systems. Unique to the AllWave ADVANTAGE optical connectivity solution (OCS), the
