Overview

The Cisco CRS-1 fiber-optic cleaning kit is used to clean all multiferrule (MT) optics in a Cisco CRS-1 Carrier Routing System Multishelf System using the Cisco CRS-1 fiber-optic cleaning kit. This kit cleans all optics on the S2 module, S13 module, optical interface module (OIM), and optical array cables.

The cleaning tool included in the kit advances a continuous roll of lint-free cleaning cloth across the face of the optic. The adapters included in the kit ensure that the cleaning tool is inserted at the proper angle and depth. Follow all instructions carefully to ensure that each optical connector is clean and free of all contaminants. This chapter provides an overview of the fiber-optic connections in the Cisco CRS-1 multishelf system; be sure to review it carefully before you begin cleaning your fiber-optic connectors.

Inspection and Cleaning

Fiber-optic connectors must be properly cleaned to eliminate any dust or contamination. Even microscopic dust particles can cause failure of a component or the whole system. In addition to dust, other contaminants, such as oils (frequently from human hands), film residues (condensed from vapors in the air), and powdery coatings (left after water or other solvents evaporate), must be cleaned from the end face. These contaminants can be more difficult to remove than dust particles and can also cause damage to equipment if not removed.

All these contaminants are cleaned using the Cisco CRS-1 fiber-optic cleaning kit, as described in this guide.

Caution Use extreme care when removing or installing connectors so that you do not damage the connector housing or scratch the end face of the fiber. Always install protective covers on unused or disconnected components to prevent contamination. Always clean fiber connectors before installing them.

CRS-1 specifications

Cisco Systems' Carrier Routing System (CRS-1) is a cutting-edge, high-capacity router designed to meet the demands of service providers and large enterprises. Introduced in the early 2000s, the CRS-1 represents a significant leap forward in routing technology, offering unparalleled performance, scalability, and reliability.

One of the primary features of the CRS-1 is its exceptional scalability. The system is built on a modular architecture that allows for easy upgrades and expansions. This enables service providers to start with a configuration that suits their immediate needs while having the flexibility to expand as traffic demands grow. The CRS-1 supports a wide range of line cards, enabling data, voice, and video to be managed on a single platform, which simplifies network management and reduces operating costs.

The CRS-1 leverages advanced technologies that enable it to deliver impressive performance. With the ability to handle up to 92 terabits per second of throughput, the router is capable of supporting a vast number of connections, making it well-suited for large-scale service providers and data centers. This level of performance is powered by Cisco’s proprietary silicon technology, which optimizes the packet forwarding process and enhances overall efficiency.

Another key characteristic of the CRS-1 is its strong focus on reliability and redundancy. The system is designed with high availability in mind, ensuring that it can continue to operate seamlessly even in the event of hardware failures. Redundant components, such as power supplies and route processors, allow the CRS-1 to maintain its performance and uptime, a critical requirement for mission-critical network operations.

Additionally, the CRS-1 supports a wide variety of protocols and technologies, including Internet Protocol (IP), Multiprotocol Label Switching (MPLS), and various service provider features. This versatility makes it a compelling choice for organizations looking to implement advanced networking capabilities, such as Quality of Service (QoS) and traffic engineering.

In summary, the Cisco Systems CRS-1 stands out as a formidable solution for modern routing needs. Its modular design, exceptional scalability, robust performance, reliability, and support for multiple protocols and services make it an ideal choice for service providers and enterprises seeking to future-proof their networks. As the demand for bandwidth continues to surge, the CRS-1 remains a pivotal component in the evolution of networking infrastructure.
