The Cisco ONS 15216 DWDM and CWDM passive optical modules are the new ONS 15216 FlexLayer units used as product enhancement to make the MSTP edge transport portfolio price competitive in price sensitive applications. The Cisco ONS 15216 DWDM and CWDM passive optical modules are 1 rack unit (RU) high and can be installed on a 19-inch (482,6 mm), 23-inch (584,2 mm) EIA standard racks, or on a 19-inch (482,6 mm) IEC rack or on a 600 mm x 600 mm or 600 mm x 300 mm ETSI rack.

The Cisco ONS 15216 Optical Supervisory Channel (OSC) Optical Add/Drop Multiplexer (OADM) is a passive device used for combining and separating a wavelength operating at 1510 nm from a composite dense wavelength-division multiplexing (DWDM) signal, while allowing other wavelengths to pass through.

As metropolitan (metro) transport networks grow from 2.5-generation (2.5G) services to 10G and eventually 40G, the underlying optical systems need to compensate for the lower chromatic dispersion tolerances on the 10G and 40G interfaces. In optical networks, the dispersion compensation unit (DCU) compensates for accumulated chromatic dispersion effect in fiber. It provides a flexible solution for accumulated chromatic dispersion without dropping and regenerating the wavelengths on the link, a process that would otherwise be necessary when accumulated chromatic dispersion exceeds the maximum allowed dispersion tolerance. To provide effective compensation, the DCU is designed to operate over the entire band from 1525 to1565 nm.
