Node Reference
This chapter explains the ONS 15454 dense wavelength division multiplexing (DWDM) node types that
are available for the ONS 15454. The DWDM node type is determined by the type of amplifier and filter
cards that are installed in an ONS 15454. The chapter also explains the DWDM automatic power control
(APC), reconfigurable optical add/drop multiplexing (ROADM) power equalization, span loss
verification, and automatic node setup (ANS) functions.
Note Unless otherwise specified, “ONS 15454” refers to both ANSI and ETSI shelf assemblies.
Note In this chapter, “OPT-BST” refers to the OPT-BST, OPT-BST-E, OPT-BST-L cards, and to the
OPT-AMP-L and OPT-AMP-17-C cards when they are provisioned in OPT-LINE (optical booster)
mode. “OPT-PRE” refers to the OPT-PRE card and to the OPT-AMP-L and OPT-AMP-17-C cards
provisioned in OPT-PRE (pre-amplifier) mode.

9.1 DWDM Node Configurations
The ONS 15454 supports the following DWDM node configurations: hub, terminal, optical add/drop
multiplexing (OADM), reconfigurable OADM (ROADM), anti-amplified spontaneous emission
(anti-ASE), line amplifier, optical service channel (OSC) regeneration line, multishelf nodes, and node
configurations for mesh networks. All node configurations can be provisioned with C-band or L-band
cards except the OADM and anti-ASE nodes. These nodes require AD-xB-xx.x or AD-xC-xx.x cards,
which are C-band only. All node configurations can be single-shelf or multishelf.
