Deployment Application
32-channel multiplexer and
demultiplexer
demultiplexer
This product provides wavelength access (on or off ramp) for all the channels in a fiber cable. Typical
deployment locations are terminal hub sites, including service provider central offices or enterprise
telecommunications facilities.

Band-optical add/drop
filters (B-OADM)
filters (B-OADM)
These filters allow access (add/drop) to a band or bands of frequencies from a fiber cable while passing the
remaining frequencies. They are typically deployed at intermediate sites where access to greater bandwidth is
required. They can also be inserted where future access to bandwidth may be required.

required. They can also be inserted where future access to bandwidth may be required.
Channel-optical add/drop
filters (C-OADM)
filters (C-OADM)
These filters enable access (add/drop) to individual wavelengths from a fiber cable while allowing the
remaining frequencies to pass. They are deployed at intermediate sites where access to individual
wavelengths is necessary. They can be cascaded to provide from 1- to 32-channel add/drop capabilities.

4-channel
multiplexer/demultiplexer
(4MD)
multiplexer/demultiplexer
(4MD)
This product provides wavelength access (on or off ramp) to four channels from a band-OADM filter. They are
deployed at intermediate sites where access to individual wavelengths is necessary.

The Cisco ONS 15454 fixed filter cards are based on the ITU 100-GHz wavelength plan. Each card integrates software-controllable variable
optical attenuators (VOAs), providing automatic node- and network-based power level management. The optical cards incorporate LEDs on the
faceplate to provide a quick visual check of the card’s operational status. An icon on each faceplate is mapped to shelf-slot icons indicating the
shelf slot where the card can be installed. The cards are supported by the integrated Cisco Transport Controller craft manager, which provides
the user access for operations, administration, maintenance, and provisioning for the system.
All Cisco ONS 15454 fixed optical filter cards can drop and reinsert a wavelength without needing to regenerate the signal (optical bypass).
This unique capability is supported at individual channel and band level and allows creation of multiring or mesh traffic matrixes using the
available fixed filter cards.
The choice of filters depends on the requirements of the network. The Cisco MetroPlanner optical design tool is available to assist in the
engineering, bill-of-material development, and deployment of the DWDM network. Figures 2 through 5 show sample signal-flow diagrams for
a selection of Cisco ONS 15454 MSTP node types, outlining the use for each filter type.
