Product Overview
The Cisco ONS 15454 MSTP offers optical amplifiers operating in the L-band region of the optical spectrum, shown in Figure 1, 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 the 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 32 channels today (designed for 64-wavelength operation) - to meet the requirements of service provider and enterprise networks. Table 1 outlines the L-band optical amplifier plug-in card types available for the Cisco ONS 15454 MSTP with the applications they are designed to support.
Table 1. L-Band Optical Amplifier Cards with Applications
The Cisco ONS 15454 L-band 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 L-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 node- and network-based automatic power-level management. Extensive optical safety algorithms provide user safety when operating the network.
Flexibility provided by the OPT-AMP-L card and the possibility to configure it through software to operate as a preamplifier or as a booster amplifier greatly simplifies the operation of the Cisco ONS 15454 MSTP and reduces the number of spare units to be kept by the users. Midstage access loss (MAL) provided by the L-band optical amplifier can be used, when the card is used as a booster amplifier, to perform chromatic dispersion precompensation at the transmit location, improving overall system performances - especially with high (that is, 10 Gbps) and very high (that is, 40 Gbps) bit rates and services.
The optical 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 is mapped to shelf-slot icons indicating the shelf slot where the card can be physically installed. The cards are supported by the integrated Cisco ONS 15454 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 L-band optical amplifiers depends 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. Figure 2 shows a sample signal-flow diagram for an L-band Cisco ONS 15454 MSTP Reconfigurable Add/Drop Multiplexing (ROADM) node type, outlining the use for each amplifier type. Figure 3 shows a sample signal-flow diagram for an L-band Cisco ONS 15454 MSTP Terminal Site (TS) node type.
