Data Sheet


Cisco ONS 15216 Metropolitan Dense Wavelength
Division Multiplexing

The Cisco ONS 15216 Cisco's Metropolitan Dense Wavelength-Division Multiplexing (DWDM) solution is the first metro DWDM solution to deliver instant wavelengths to buildings, premises, or points of presence (POPs). The Cisco ONS 15216 supercharges wavelength services by supporting up to 32 ITU-grid wavelengths, and provides unprecedented transport flexibility with optical filtering, optical add/drop multiplexing (OADM), optical performance monitoring, and amplification. The Cisco ONS 15216 allows service providers to deliver more services per wavelength and more wavelengths per fiber to achieve radical economic benefits.

The Cisco ONS 15216 optical filter solution enables service providers to deploy point-to-point, bus, ring, and meshed networks using the terminal filter multiplexing and demultiplexing and OADM. The Cisco ONS 15216 platform provides an open and flexible solution to combine wavelengths launched by the Cisco ONS 15454, ONS 15252, ONS 15201, and ONS 15530. The Cisco ONS 15216 supercharges wavelength services and extends Cisco's optical leadership to metro regional DWDM.

The Cisco ONS 15216 Metropolitan DWDM filter solution for 100-GHz wavelength spacing includes the following elements:

32-wavelength terminal filter solution (multiplexing and demultiplexing)

16-wavelength base red filter

16-wavelength upgrade blue filter

OADMs

One-channel, two-path OADM

Two-channel, two-path OADM

Four-channel, two-path OADM

32-Wavelength Terminal Filter

The Cisco ONS 15216 red and blue filters allow service providers to multiplex multiple ITU grid wavelengths launched by the Cisco ONS 15454 and ONS 15252 onto a single fiber, maximizing network capacity and fiber utilization.

The Cisco ONS 15216 Base Red Filter

The base filter assembly, the Cisco ONS 15216 red filter, is a passive unit comprising a 100-GHz 16-x-1 wavelength unidirectional multiplexer (mux) and a 100-GHz 1-x-16 wavelength unidirectional demultiplexer (demux) operating in the 1546- to 1561-nanometer (nm) frequency band. The mux and demux systems connect independent fibers to the carrier's fiber facilities through the common ports on the chassis faceplate. The base unit integrates two pairs of expansion ports, enabling in-service upgrades from 16 mux/demux wavelengths to 32 wavelengths. The base unit also incorporates two monitor ports, allowing the user unobtrusive access to the transmit and receive signals (see Figure 1) for monitoring or analysis. The filter mounts in a 19- or 23-inch rack and occupies two rack units (RU).

The Cisco ONS 15216 Upgrade Blue Filter

The upgrade filter assembly, the Cisco ONS 15216 blue filter, is a passive unit comprising a 100-GHz 1-x-16 wavelength unidirectional multiplexer and a 100-GHz 1-x-16 wavelength unidirectional demultiplexer operating in the 1530- to 1545-nm frequency band. The front-panel common connector ports on the upgrade filter are used to connect to the base unit's upgrade ports via user-supplied optical patch cords. The filter mounts in a 19- or 23-inch rack and occupies two RU.

Cisco ONS 15216 OADMs

The Cisco ONS 15216 optical add/drop multiplexers (OADMs) allow service providers to deliver wavelengths to the building in single-channel increments, and to combine wavelengths from the Cisco ONS 15454, ONS 15252, ONS 15201, and ONS 15530 platforms.

The Cisco ONS 15216 offers three OADMs: A one-channel, two-path OADM that allows service providers to add and drop one protected channel (one in each direction east and west) at any point in a DWDM ring; a two-channel, two-path OADM that allows service providers to add and drop two protected channels; and a four-channel, two-path OADM that allows service providers to add and drop four protected channels (See Figures 3, 4, and 5). The 1 and 2 Channel OADMs are packaged in a compact, 1-RU 19- or 23-inch rack-mounted shelf. The 4 Channel OADM is packaged in a compact, 2-RU 19- or 23-inch rack-mounted shelf. Software-controlled variable optical attenuators are available at the add ports of the units to attenuate the power level of the added channel to match the express stream. This enables the user to ensure the channel being added does not negatively impact the uniformity of the spectrum. This is particularly important for amplified applications where the flatness response of the C-band erbium doped fiber amplifier (EDFA) is directly linked to the uniformity of the input stream. Two output monitor tap ports are also provided in the same chassis to monitor the outgoing signals in east and west directions.

Cisco ONS 15216 EDFA-2

The Cisco ONS 15216 Erbium Doped Fiber Amplifier 2 (EDFA-2) is a C-Band amplifier, which allows all of the 32 channels to be amplified. This is a unidirectional device and is packaged in a 1-RU 19- or 23-inch rack-mounted shelf. The amplifier's high gain and performance allows for the design of systems which have channels that span hundreds of kilometers. Using the Automatic Gain Control, designs and systems can gracefully grow from 1 to 32 channels without complete equipment upgrades. This amplifiers has active monitoring capabilities via it's Ethernet or RS-232 interfaces. It also incorporates an output tap for unobtrusive monitoring of the launched DWDM signal and contact closure outputs for alarm reporting.

Cisco ONS 15216 OPM

The Cisco ONS 15216 Optical Performance Monitor (OPM) is a device that provides proactive monitoring and alarming capabilities of the DWDM line by monitoring each of the wavelengths within the DWDM system. On a per-wavelength basis, the OPM can monitor and alarm the center wavelength, channel power, and optical signal-to-noise ratio (OSNR). This active monitoring function is done in a 2-RU 19- or 23- inch rack-mounted shelf. It can monitor up to two DWDM lines per device. This is important for detecting degradation of optical signals and for ease of troubleshooting in complex DWDM systems.

Cisco ONS 15216 DCU

The Cisco ONS 15216 dispersion compensation units (DCUs) are devices that provide compensation of chromatic dispersion for SMF-28 fiber. These units apply to the entire C-band allowing one or many wavelengths to be compensated. These devices are mounted in a 1-RU 19- or 23- inch rack mounted shelf. This shelf offers two slots that can be populated with 350, 750, or 1150 ps/nm passive DCU modules. These devices are critical in extending the distance between 3R regeneration points for 10-Gbps networks.

Cisco ONS 15216 Solution Benefits

Supercharged wavelength services—Allows service providers to aggregate subwavelength services onto DWDM networks to maximize service density and revenue per wavelength. Subwavelength services can be combined with wavelength services on the same network.

Unprecedented transport flexibility—Supports a range of applications from point-to-point DWDM to more advanced OADM rings scaling to several-hundred-kilometer ring circumferences. Supports up to 32 OADM sites, using a combination of Cisco ONS 15252, ONS 15201 metro DWDM platforms, and ONS 15454 and ONS 15327 optical transport platforms.

Radical economics—Value reduces network costs by eliminating transponders using the ITU interfaces available for the Cisco ONS 15454 or other ITU-enabled, multiservice platforms. Also provides highly cost-effective solutions for transponder-based services using the Cisco ONS 15252 and ONS 15201, particularly for amplified networks where the Cisco ONS 15216 EDFA is used.

Small footprint—The one-channel and two-channel OADMs are only a single RU, and the mux/demux terminal filters and four-channel OADMs are only two RUs, saving costly equipment space.

Easy channel upgrades—Upgrades from base red filters to blue filters can be accomplished without disturbing existing channels on the red filter. Additional OADM sites can easily be added by switching over traffic to the protection path.

Network management integration—The active components in the filter solution—the OADMs—are managed through the Cisco Transport Manager element management system. Cisco Transport Manager provides integrated management of the complete optical network, including all other Cisco optical products.
