2.2.4 Optical Amplifiers
The optical amplifier cards can be installed in Slots 1 through 6 and 12 through 17.
These cards contain three main modules:
•Optical plug-in module
•Microprocessor module (uP8260)
•DC/DC converter
The optical plug-in module has a built-in microcontroller for managing functionalities such as the
optical power, laser current, and temperature control loops.
The microprocessor module (uP8260) manages the communication between the optical amplifier card
and the TCC2/TCC2P card, and provides all the Operation, Administration, Maintenance, and
Provisioning (OAM&P) functions (including controls and alarms). The DC/DC converter provides the
power supply voltages for the cards.
The Cisco ONS 15454 has five optical amplifier cards:
•C-Band Preamplifier (OPT-PRE)
•C-Band Booster (OPT-BST)
•C-Band Booster Enhanced (OPT-BST-E)
•L-Band Amplifier (OPT-AMP-L)
•L-Band Booster (OPT-BST-L)
