Cards Specifications

This chapter contains specific information about cards for dense wavelength division multiplexing (DWDM) applications in the Cisco ONS 15454.

Note The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.

The following topics are covered in this chapter:

•2.1 Card Overview, page 2-1

•2.2 Card Specifications, page 2-12

2.1Card Overview

Redundant TCC2 and TCC2P cards are required to operate the Cisco ONS 15454. If you are using an ETSI (SDH) shelf assembly, the MIC-A/P and MIC-C/T/P front mount electrical connections (FMECs) are also required. The optional AIC-I card provides external alarms and controls (environmental alarms).

Each DWDM card is marked with a symbol that corresponds to a slot (or slots) on the ONS 15454 shelf assembly. These cards can only be installed into slots displaying the same symbols.

ONS 15454 DWDM cards are grouped into the following categories:

•Optical service channel OSC) cards provide bidirectional channels that connect all the ONS 15454 DWDM nodes and transport general-purpose information without affecting the client traffic.

ONS 15454 OSC cards include the Optical Service Channel Module (OSCM) and the Optical Service Channel and Combiner/Separator Module (OSC-CSM).

•Optical erbium-doped fiber amplifier (EDFA) cards are used in amplified DWDM nodes, including hub nodes, amplified OADM nodes, and line amplified nodes. Optical amplifier cards include the Optical Preamplifier (OPT-PRE) and Optical Booster (OPT-BST).

•Dispersion compensation units (DCUs) are installed in the ONS 15454 dispersion compensation shelf when optical preamplifier cards are installed in the DWDM node. Each DCU module can compensate a maximum of 65 km of single-mode fiber (SMF-28) span. DCUs can be cascaded to extend the compensation to 130 km.

15454 specifications

Cisco Systems' 15454 is a leading optical networking platform designed to address a range of connectivity needs for service providers, enterprises, and data centers. As part of the Cisco ONS (Optical Networking System) portfolio, the 15454 provides advanced capabilities that cater to the evolving demands of high-performance network requirements.

At its core, the Cisco 15454 is built for scalability and versatility. It supports a variety of transmission methods, including SONET (Synchronous Optical Networking), SDH (Synchronous Digital Hierarchy), and WDM (Wavelength Division Multiplexing). This flexibility makes the platform ideal for deploying both legacy services and next-generation applications.

One of the standout features of the 15454 is its ability to support high-capacity wavelengths, allowing for greater bandwidth utilization across fiber networks. With advanced Dense Wavelength Division Multiplexing (DWDM) technology, the platform ensures efficient use of the available fiber and extends the distance over which data can be transmitted. This results in reduced operational costs while maximizing throughput.

The Cisco 15454 also comes equipped with an array of interfaces supported by its modular design. The platform can accommodate Ethernet, SONET/SDH, and IP services, which means it can seamlessly handle a wide range of protocols. The modular architecture allows network operators to tailor the system to their specific requirements, offering a variety of line cards and interfaces to choose from.

Another critical characteristic of the 15454 is its built-in protection mechanisms. The system offers diverse and automatic protection schemes such as optical Layer 1 protection, ensuring high availability and network resilience. This capability is essential for mission-critical applications where uptime is paramount.

Moreover, the platform is complemented by Cisco's sophisticated management solutions, which streamline the operational management of the network. With tools that provide in-depth monitoring and troubleshooting capabilities, network administrators can maintain optimal performance and quickly respond to any issues that may arise.

In summary, the Cisco Systems 15454 is a robust and adaptable optical networking solution. Its main features, including advanced DWDM capabilities, modular architecture, protocol versatility, and enhanced protection mechanisms, make it a preferred choice for organizations looking to scale their network infrastructure while ensuring high service reliability and performance. Whether for expanding bandwidth or modernizing legacy networks, the Cisco 15454 stands out as a powerful tool in the ever-evolving landscape of telecommunications.
