Description
The Cisco 15454-40-SMR2-C is a 40-channel single-module Reconfigurable Optical Add/Drop Multiplexer (ROADM) card designed for use in the Cisco ONS 15454 Multiservice Transport Platform (MSTP). It combines a wavelength-selective switch (WSS) based ROADM core with integrated optical pre-amplifier and boost amplifier stages, enabling high-capacity wavelength routing and flexible optical network topologies. This card supports ITU-standard 100 GHz 40-channel C-band DWDM grids and can be used to build mesh and multi-ring optical networks with degree-4 node support.
