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-Band Optical Add/Drop Multiplexer card enables add/drop access to four adjacent bands of frequencies from a fiber pair while passing the remaining frequencies. They are typically deployed at intermediate sites where access to large amounts of bandwidth is required. They can also be inserted at sites where future access to bandwidth may be required. 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. This card can be coupled with the Cisco ONS 15454 4-Channel Multiplexer/Demultiplexer card to access individual wavelengths. The 4-Band OADM card is already compatible with 50GHz wavelength spacing, allowing future 32-channel add/drop capabilities from the ONS 15454 MSTP platform.
