The Cisco ONS 15454 optical filter cards are plug-in modules that take advantage of the proven Cisco ONS 15454 carrier-class features to deliver multiservice transport platform (MSTP) capabilities with the flexibility to access network bandwidth from a single DWDM channel all the way to 32 channels, to support the requirements of service provider and enterprise networks.
The Cisco ONS 15454 4-Ch. 100GHz Optical Multiplexer/Demultiplexer card provides wavelength access (aggregation and demultiplexing) to up to four channels from band-OADM filters. They are deployed along with the band-OADM filters where access to individual wavelengths is necessary from a specific band. This card provides integrated variable optical attenuators to leverage the Cisco ONS 15454 MSTP's intelligence to automatically control the power levels for the entire DWDM network. These cards can be combined with the other Cisco ONS 15454 MSTP WDM transmission elements to provide from 1- to 4-channel add/drop capabilities.
