Cisco ONS 15540 ESPx Cleaning Procedures for Fiber Optic Connections
This document describes the processes and procedures for cleaning the fiber optic connectors and component interfaces of the Cisco ONS 15540 ESPx. It is intended for use by service personnel, field service technicians, and hardware installers. It is assumed that the user has knowledge of basic inspection techniques and cleaning processes for fiber optic connectors and component interfaces.
Warning 
Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Warning Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not view directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye hazard.

Introduction
Cleaning the fiber optic components of the Cisco ONS 15540 ESPx is important for maintaining the system. Any contamination in the fiber connection can cause failure of the component or failure of the entire system.
Microscopic dust particles can cause a variety of problems for optical connectors. A particle that partially or completely blocks the fiber core generates strong back reflections, which can cause instability in the laser system. Dust particles trapped between two fiber faces can scratch the glass surfaces. Even if a particle is only situated on the cladding or the ferrule, it can cause an air gap or misalignment between the fiber cores that can significantly degrade the optical signal.
•A 1-micrometer dust particle on a single-mode core can block up to 1% of the light (a 0.05 dB loss).
•A 9-micrometer speck is too small to see without a microscope, but it could completely block the fiber core.
By comparison, a typical human hair is 50 to 75 micrometers in diameter, as much as 8 times larger. So, even though dust may not be visible, it is still present in the air and can deposit onto the connector.
In addition to dust, other types of contamination must also be cleaned off the fiber. Such materials include:
•Oils (frequently from human hands)
•Film residues (condensed from vapors in the air)
•Powdery coatings (left after water or other solvents evaporate away)
These contaminants can be more difficult to remove than dust particles.
Caution With 1- to 200-mW power in a fiber (0 to 23 dBm) now in use for communications systems, any contaminant can be burned into the fiber end face if it blocks the core while the laser is turned on. This burning may damage the optical surface such that it cannot be cleaned.
When cleaning fiber components, procedures must be followed precisely and carefully with the goal of eliminating any dust or contamination. A clean component connects properly; a dirty component may transfer contamination to the connector, or it may even damage the optical contacts.
Inspecting, cleaning, and re-inspecting are critical steps that must be done before making any fiber connection.
Inspection Equipment
It is important that every fiber connector be inspected with a microscope before a connection is made as many of the contaminants are too small to see with the naked eye. The fiber inspection scopes (not included in the Cisco ONS 15540 ESPx cleaning kit) described in this section are designed to magnify and display the critical portion of the ferrule where the connection is made.
Video and Optical Fiberscopes
Fiberscopes are customized microscopes used to inspect optical fiber components. Figure 1, Figure 2, and Figure 3 show examples of the various fiber scopes available. The scope you chose should provide at least 200x magnification. Specific adapters are needed to properly inspect the ferrule faces of some connector types (such as the MPO, E2000, or MU connectors). In instances where multiple connector types need inspection, it may be more efficient to have a dedicated scope for each type of adapter.
Note To ensure personal eye safety, we strongly recommend that a video fiberscope be used for inspections. Be certain that optical fiberscopes have the appropriate wavelength band filters to protect the user.
Figure 1 Video Fiberscope—Desktop
Figure 2 Optical Fiberscopes—Handheld
Bulkhead Fiberscope
The bulkhead fiberscope is a handheld fiberscope used to inspect connectors in bulkhead ports. The scope should provide at least 200x magnification displayed on a video monitor. Specific adapters are needed to properly inspect the ferrule faces of some connector types (such as the MPO, E2000, or MU connectors). See Figure 3.
Figure 3 Bulkhead Fiberscope—Handheld
Laser Safety Glasses
Laser safety glasses can protect a person's eyes from laser light while handling fiber. They are intended to provide a level of protection across specific wavelengths. Be sure that the glasses are matched to the laser's wavelength. Laser safety glasses must meet federal and state regulations.

Cartridge Cleaners
Cartridge cleaners contain a roll of woven material packaged in a cassette (see Figure 4). When a lever is pressed, a shutter opens to provide access to a fresh span of cleaning material. The following cartridges are included in the cleaning kit:
•Cartridge cleaner (OPTIPOP) MPO/MTP with/pins
Used to perform dry cleaning of MPO/MTP male connectors. It has two guide slots in the cleaning window. When the lever is pressed a shutter opens to provide a new section of the cleaning material.
•Cartridge cleaner (OPTIPOP) one slot
Used to perform dry cleaning of 2.5-mm (SC, FC, and so on) and 1.25-mm (MU, LC, and so on) ferrule connectors and female multi-fiber connectors such as MT-RJ. When the lever is pressed, a shutter opens to provide a new section of the cleaning material.
Note The ferrule is the part of the connector that keeps the fiber accurately aligned within the connector.
Figure 4 Cartridge Cleaner
Lint-Free Swabs
Swabs have a fabric tip at the end of a long stick. Lint-free swabs should be stored in a clean container to avoid contamination of the tip. Be sure to use a swab sized properly for the ferrule type (1.25 mm or 2.5 mm). See Figure 5.
Caution Never reuse a swab, it could transfer dirt or oils from one connector to another.

Inspecting the Cisco ONS 15540 ESPx Fiber Optic Connections
Inspecting the fiber optic connectors for dust particles or other contaminants before bringing the card or module online can help to prevent system failures. Always work carefully around lasers and fiber optic connections. Keep the following information in mind.
•Always turn off any laser sources before you inspect fiber connectors or optical components.
•Always inspect the connectors or adapters before you clean.
•Always inspect and clean the connectors before you make a connection.
•Always use the connector housing to plug or unplug a fiber.
•Always keep the protective cap on unplugged fiber connectors.
•Always store unused protective caps in a resealable box and locate them near the connectors for easy access.
•Always discard used lint-free swabs properly.
•Always wear appropriate safety glasses when required in your production area.
•Never look into a fiber while the system lasers are on.
•Never use unfiltered handheld magnifiers or focusing optics to inspect fiber connectors.
•Never connect a fiber to a fiberscope while the system lasers are on.
•Never touch the end face of the fiber connectors.
•Never twist or pull forcefully on the fiber cable.
•Never reuse any lint-free swab or OPTIPOP cartridge cleaner reel.

TAC Case Priority Definitions
To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.
Priority 1 (P1)—Your network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
