Cisco Optical Preamplifier

The Cisco® ONS 15454 Multiservice Transport Platform (MSTP) provides a comprehensive, intelligent dense wavelength-division multiplexing (DWDM) solution for expanding metropolitan (metro) and regional bandwidth.

The Cisco ONS 15454 MSTP offers optical amplifiers for extending the reach of a metro or regional network. The optical amplifier cards are part of the Cisco ONS 15454 MSTP intelligent DWDM architecture engineered to reduce DWDM complexity and speed the deployment of next-generation networking solutions.
The Cisco ONS 15454 optical amplifier cards are plug-in modules that take advantage of proven Cisco ONS 15454 carrier-class features. These cards deliver the reach and optical performance to support a single DWDM channel all the way to 40 channels today (designed for 80-wavelength operation) - to meet the requirements of service provider and enterprise networks. Table 1 outlines the optical amplifier plug-in card types available for the Cisco ONS 15454 MSTP with the applications they are designed to support.

This product amplifies the incoming composite DWDM signal to allow a sufficient optical power level to optical receivers on dropped wavelengths and to overcome the insertion losses of optical filters in the node. It employs a two-stage amplifier design to allow insertion of dispersion-management devices to compensate for pulse spreading at higher multiplexer speeds. Deployment locations include any site that requires additional signal level.
