Product Description

Used Cisco ONS 15216 100-GHz OADM1
Cerent 15200 Series

The Cisco ONS 15216 is part of the Cisco ONS 15200 Metropolitan Dense Wavelength Division Multiplexing (DWDM) solution, 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, and ring 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 15540. 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 is comprised of the following elements:

• Terminal filter solution (multiplexing and demultiplexing)

• Base red filter

• Upgrade blue filter

• Two-path OADM

• Two-path OADM

• Two-path OADM

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 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 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.
