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
1665 DMX 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.

1665 DMX 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
