ONS 15454 Multiservice Transport Platform (MSTP) (Figure 1) provides a
comprehensive, intelligent dense wavelength-division multiplexing (DWDM) solution for
expanding metropolitan (metro) and regional bandwidth.

Product Overview
Release 8.0 expands Cisco ONS 15454 MSTP transport capacity in C band to 40 channels (100-
GHz spacing) and to 80 channels (50-GHz spacing). In parallel with the existing 32-channel
Reconfigurable Optical Add/Drop Multiplexing (ROADM) solutions, a new set of units is introduced
in this release to enhance reconfigurability options for the MSTP platform, allowing multidegree
reconfigurability as well. By making use of the Release 8.0 MSTP features and configuration
flexibility, a Cisco DWDM network can scale to 112 channels of composite DWDM traffic, using
both the C band and the L band spectrum.
The new 40-channel Wavelength Cross-Connect (40-WXC) card and the software functionalities
extended from previous releases provide multidegree switching capabilities at the individual
wavelength level. Mesh and multiring network topologies can now be deployed using Cisco ONS
15454 MSTP platform with complete flexibility of service routing at all nodes in the network. While
Wavelength Selective Switch (WSS) units provide degree-2 type reconfigurability (drop wavelength
in a node vs. let it pass through the node), an ROADM node based on 40-WXC units can support
up to degree-8 reconfigurability. This means that for each wavelength it is possible to decide if it
has to be locally dropped or routed to any of the other 7 pass-through directions of the node. Such
a capability not only enhances the flexibility of the DWDM transport network but also dramatically
reduces the need for costly transponders to perform optical-to-electrical-to-optical conversion
(typically 2 transponders/crossponders per add/drop channel or wavelength). This capability allows
