C H A P T E R 1 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.
Chapter 1 Overview General Reminders and Warnings General Reminders and Warnings Review these reminders and warnings before inspecting and cleaning your fiber-optic connections. Warning Because invisible radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures. Statement 125 Warning Class 1M laser radiation when open. Do not view directly with optical instruments. Statement 281 Warning Laser radiation.
Chapter 1 Overview Fiber-Optic Connectors in a Multishelf System • High-density backplane-mounted (HBMT) connectors: the optical connectors on the back of the S2 and OIMs. These connectors provide the optical path between an S2 card and its corresponding OIM. Figure 1-1 shows the fiber-optic connections in an FCC. Figure 1-2 shows the fiber-optic connections in an LCC.

Chapter 1 Overview About the Cisco CRS-1 Fiber-Optic Cleaning Kit About the Cisco CRS-1 Fiber-Optic Cleaning Kit All optical connections in a multishelf system are cleaned using the Cisco CRS-1 fiber-optic cleaning kit. This kit includes a tool that advances a lint-free cloth across the optical surface to remove any contaminants. The cleaning kit also includes an adapter for each connector type. The adapter ensures that the cleaning tool is inserted at the correct angle and depth for cleaning.

Chapter 1 Overview About the Cisco CRS-1 Fiber-Optic Cleaning Kit OIM HBMT Adapter 158208 Figure 1-6 Description of the Fujikura IBC Cleaning Tool Use the Fujikura IBC cleaning tool (see Figure 1-7) to clean the ferrules of your fiber optic connectors. Note Be sure to replace the protective cap after each use of the cleaning tool.
Chapter 1 Overview About the Cisco CRS-1 Fiber-Optic Cleaning Kit Figure 1-7 Fujikura IBC Cleaning Tool and Clear Protective Cap 138657 1 2 3 1 Thumb wheel 2 Cleaning head 3 Protective cap Use the thumb wheel of the cleaning tool to advance the cleaning surface (see Figure 1-8) after cleaning each ferrule so as to ensure a clean section for the next ferrule. The cleaning tool includes an alignment edge and key to help you properly align it with the optical interface surfaces during cleaning.
Chapter 1 Overview Using the Fujikura IBC Cleaning Tool Figure 1-8 Fujikura IBC Cleaning Tool Head and Alignment Edge 1 3 138658 2 1 Cleaning head 2 Alignment edge 3 Key Using the Fujikura IBC Cleaning Tool To operate the cleaning tool, complete the following steps for each ferrule: Step 1 Attach an ESD-preventive wrist strap to your wrist and connect its leash to an ESD connection socket or a bare metal surface on the chassis.
Chapter 1 Overview Using the Fujikura IBC Cleaning Tool Step 4 To clean the surface, advance the white thumb wheel until you hear two hard clicks. This action moves a continuous roll of lint-free cleaning cloth across the surface of the fibers, removing dust and other contaminants. The cleaning tool holds enough cloth to clean well over 100 ferrules. Note The thumb wheel makes a series of soft clicks followed by a “hard click” when turned.
2 C H A P T E R Cleaning the Optical Array Cable Connectors This chapter provides instructions for cleaning the ferrules in the optical array cable connectors. These connectors are at both ends of the fiber-optic cables that connect the S13 cards in the line card chassis (LCC) to the optical interface modules (OIMs) in the fabric card chassis (FCC).
Chapter 2 Cleaning the Optical Array Cable Connectors How to Clean the Optical Array Cable Connectors How to Clean the Optical Array Cable Connectors Each optical array cable connector contains six optical ferrules. To access all ferrules, you must clean three ferrules and then rotate the adapter 180 degrees to clean the remaining three ferrules. This section describes the process to clean all ferrules in an optical array cable.
