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.
