Optical Amplifier Cards
This chapter describes the optical amplifier cards used in Cisco ONS 15454 dense wavelength division
multiplexing (DWDM) networks. For installation and card turn-up procedures, refer to the
Cisco ONS 15454 DWDM Procedure Guide. For card safety and compliance information, refer to the
Cisco Optical Transport Products Safety and Compliance Informationdocument.

4.1 Card Overview
This section provides summary and compatibility information for the optical amplifier cards.

Note

Each card is marked with a symbol that corresponds to a slot (or slots) on the ONS 15454 shelf assembly.
Cardsshould be installed in slots that have the same symbols. See the “1.16.1 Card Slot Requirements”
section on page 1-61 for a list of slots and symbols.
Optical amplifiers are used in amplified nodes (such as hub nodes), amplified OADM nodes, and line
amplifier nodes. The seven types of ONS 15454 DWDM amplifiers are:

Optical Booster amplifier(OPT-BST)

Optical C-band long-haul span loss reduction (in unregenerated sections) amplifier (OPT-RAMP-C)

The OPT-AMP-L preamplifier, OPT-AMP-C, and OPT-AMP-17-C amplifiers are software-configurable
as a preamplifier or as a booster amplifier.
Optical amplifier card architecture includes an optical plug-in module with a controller that manages
optical power, laser current, and temperaturecontrol loops. An amplifier also manages communication
with the TCC2/TCC2P card and operation, administration, maintenance, and provisioning (OAM&P)
functions such as provisioning, controls, and alarms.

4.1.1 Applications
Using CTC (CTC > Card > Provisioning), the following amplifiers can be configured as booster or
preamplifiers:
•

OPT-AMP-C

•

OPT-AMP-17C

•

OPT-AMP-L

•OPT-BST-E

•

OPT-BST

The amplifier functions as a booster amplifier when equipped in slots 1, 3, 5, 13, 15, 17 and as a
preamplifiers when equipped in Slots 2, 4, 6, 12, 14, 16. If the node is installed using the CTP NE update
configuration file, the amplifier role is automatically implemented by CTP and hence, no manual
configuration is necessary.

Note

The OPT-BST andOPT-BST-E amplifiers are supported as preamplifiers in sites that are equipped with
the OPT-RAMP-C card. In any other configuration, the OPT-BST and OPT-BST-E cards must be
configured as a booster amplifier.
For more information about the supported configurations and network topologies, see Chapter 10, “Node
Reference” and Chapter 11, “Network Reference.”
