Network Reference
This chapter explains the ONS 15454 dense wavelength division multiplexing (DWDM) network
applications and topologies. The chapter also provides network-level optical performance references.
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, OPT-AMP-C, 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, OPT-AMP-C, and
OPT-AMP-17-C cards provisioned in OPT-PRE (pre-amplifier) mode.
Note OPT-BST-L, 32WSS-L, 32DMX-L, and OPT-AMP-L cards can only be installed in L-band-compatible
nodes and networks. OPT-BST, OPT-BST-E, 32WSS, 32DMX, 40-DMX-C, 40-DMX-CE, 40-MUX-C,
40-WSS-C, 40-WSS-CE, 40-WXC-C, OPT-AMP-C, and OPT-AMP-17-C cards can only be installed in
C-band-compatible nodes and networks.
