DATA SHEET

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.

PRODUCT OVERVIEW

The Cisco ONS 15454 MSTP offers enhanced optical booster amplifiers for extending the reach of a metro or regional network. The enhanced 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 enhanced optical amplifier cards (Figure 1) 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 64 channels today-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.

Component

Deployment Application

Enhanced optical booster amplifier (OPT-BST-E)

This product amplifies the outgoing composite DWDM signal to overcome the attenuation of the fiber network. It integrates an optical service channel splitter/combiner to allow the optical supervisory channel (OSC) to be sent to and received from the optical service channel module (OSCM) card.

Optical booster amplifier (OPT-BST)

This product amplifies the outgoing composite DWDM signal to overcome the attenuation of the fiber network. It integrates an optical service channel splitter/combiner to allow the OSC to be sent to and received from the OSCM card. Deployment locations include any site that requires additional signal level.

Optical preamplifier (OPT-PRE)

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.

 
The Cisco ONS 15454 optical amplifiers take advantage of the latest in amplifier technology, variable optical attenuators, photo diodes, and extensive software to facilitate a high degree of automation for simplified operations. They feature low-noise-gain blocks for C-band optical-amplification requirements. For flexibility of application support, the amplifiers support two modes of operation, constant gain and constant power. They also provide fast-transient suppression to respond quickly to network changes without adding impairments and degradation. Each card integrates software-controllable variable optical attenuators (VOAs) along with extensive optical monitoring with photo diodes, to provide nodal- and network-based automatic power-level management. Extensive optical safety algorithms provide user safety when operating the network.
The enhanced booster amplifier cards incorporate faceplate-mounted LEDs to provide a quick visual check of the operational status at the card. Printed on each of the faceplates is an icon, an orange circle, which corresponds to shelf-slot icons located on the shelf assembly, indicating the shelf slot where the cards can be inserted. The cards are supported by the integrated Cisco Transport Controller craft manager, which provides the user access for operations, administration, maintenance, and provisioning (OAM&P) for the system.
Selection and deployment of the optical amplifiers depend 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 4 show sample signal-flow diagrams for a selection of Cisco ONS 15454 MSTP node types, outlining the use for each amplifier type.
