Cleaning Information The following Cleaning Information contains some general safety precautions, which must be observed during all phases of cleaning. Consult your specific optical device manuals or guides for full information on safety matters. Please try, whenever possible, to use physically contacting connectors, and dry connections. Clean the connectors, interfaces, and bushings carefully after use.
Safety Precautions Cleaning Information Safety Precautions Please follow the following safety rules: • Do not remove instrument covers when operating. • Ensure that the instrument is switched off throughout the cleaning procedures. • Use of controls or adjustments or performance of procedures other than those specified may result in hazardous radiation exposure. • Make sure that you disable all sources when you are cleaning any optical interfaces.
Cleaning Information What do I need for proper cleaning? Furthermore, the power density may burn dust into the fiber and cause additional damage (for example, 0 dBm optical power in a single mode fiber causes a power density of approximately 16 million W/m2). If this happens, measurements become inaccurate and non-repeatable. Cleaning is, therefore, an essential yet difficult task.
What do I need for proper cleaning? Cleaning Information We suggest these protective coverings should be kept on the equipment at all times, except when your optical device is in use. Be careful when replacing dust caps after use. Do not press the bottom of the cap onto the fiber too hard, as any dust in the cap can scratch or pollute your fiber surface. If you need further dust caps, please contact your nearest Agilent Technologies sales office.
Cleaning Information What do I need for proper cleaning? Soft tissues These are available from most stores and distributors of medical and hygiene products such as supermarkets or chemists' shops. We recommend that you do not use normal cotton tissues, but multilayered soft tissues made from non-recycled cellulose. Cellulose tissues are very absorbent and softer. Consequently, they will not scratch the surface of your device over time.
What do I need for proper cleaning? Cleaning Information When spraying compressed air, hold the can upright. If the can is held at a slant, propellant could escape and dirty your optical device. First spray into the air, as the initial stream of compressed air could contain some condensation or propellant. Such condensation leaves behind a filmy deposit. Please be friendly to your environment and use a CFC-free aerosol.
Cleaning Information What do I need for proper cleaning? Only use isopropyl alcohol in your ultrasonic bath, as other solvents may cause damage. Warm water and liquid soap Only use water if you are sure that there is no other way of cleaning your optical device without causing corrosion or damage. Do not use hot water, as this may cause mechanical stress, which can damage your optical device. Ensure that your liquid soap has no abrasive properties or perfume in it.
Preserving Connectors Cleaning Information Preserving Connectors Listed below are some hints on how best to keep your connectors in the best possible condition. Making Connections Before you make any connection you must ensure that all cables and connectors are clean. If they are dirty, use the appropriate cleaning procedure. When inserting the ferrule of a patchcord into a connector or an adapter, make sure that the fiber end does not touch the outside of the mating connector or adapter.
Cleaning Information Which Cleaning Procedure should I use ? Which Cleaning Procedure should I use ? Light dirt If you just want to clean away light dirt, observe the following procedure for all devices: • Use compressed air to blow away large particles. • Clean the device with a dry cotton swab. • Use compressed air to blow away any remaining filament left by the swab. Heavy dirt If the above procedure is not enough to clean your instrument, follow one of the procedures below.
How to clean connector adapters Cleaning Information To assess the projection of the emitted light beam you can use an infrared sensor card. Hold the card approximately 5 cm from the output of the connector. The invisible emitted light is projected onto the card and becomes visible as a small circular spot. Preferred Procedure Use the following procedure on most occasions. 1 Clean the connector by rubbing a new, dry cotton swab over the surface using a small circular movement.
Cleaning Information Preferred Procedure How to clean connector interfaces Use the following procedure on most occasions. 1 Clean the adapter by rubbing a new, dry cotton swab over the surface using a small circular movement. 2 Blow away any remaining lint with compressed air. Procedure for Stubborn Dirt Use this procedure when there is greasy dirt on the adapter: 1 Moisten a new cotton swab with isopropyl alcohol.
How to clean bare fiber adapters Cleaning Information 3 Moisten a new cotton swab with isopropyl alcohol. 4 Clean the interface by rubbing the cotton swab over the surface using a small circular movement. 5 Using a new, dry pipe cleaner, and a new, dry cotton swab remove the alcohol, any dissolved sediment and dust. 6 Blow away any remaining lint with compressed air. How to clean bare fiber adapters Bare fiber adapters are difficult to clean. Protect from dust unless they are in use.
Cleaning Information How to clean lenses How to clean lenses Some lenses have special coatings that are sensitive to solvents, grease, liquid and mechanical abrasion. Take extra care when cleaning lenses with these coatings. Lens assemblies consisting of several lenses are not normally sealed. Therefore, use as little alcohol as possible, as it can get between the lenses and in doing so can change the properties of projection. Preferred Procedure Use the following procedure on most occasions.
How to clean instruments with an optical glass plate Cleaning Information If there are fluids or fat in the connector, please refer the instrument to the skilled personnel of Agilent’s service team. CA U TI O N Only use clean, dry compressed air. Make sure that the air is free of dust, water, and oil. If the air that you use is not clean and dry, this can lead to filmy deposits or scratches on the surface of your connector interface. This will degrade the performance of your transmission system.
Cleaning Information WARNING How to clean instruments with a recessed lens interface Never look into an optical output, because this can seriously damage your eyesight. To assess the projection of the emitted light beam you can use an infrared sensor card. Hold the card approximately 5 cm from the interface. The invisible emitted light is projected onto the card and becomes visible as a small circular spot. Preferred Procedure Use the following procedure on most occasions.
How to clean optical devices which are sensitive to mechanical stress and pressure Preferred Procedure Cleaning Information Use the following procedure on most occasions. 1 Blow away any dust or dirt with compressed air. If this is not sufficient, then 2 Clean the interface by rubbing a new, dry cotton swab over the surface using a small circular movement. 3 Blow away any remaining lint with compressed air.
Cleaning Information How to clean metal filters or attenuator gratings procedure is time-consuming, but you avoid scratching or destroying the surface. 1 Put the film on the surface and wait at least 30 minutes to make sure that the film has had enough time to dry. 2 Remove the film and any dirt with special adhesive tapes. Alternative Procedure For these types of optical devices you can often use an ultrasonic bath with isopropyl alcohol.
Additional Cleaning Information Cleaning Information Additional Cleaning Information The following cleaning procedures may be used with other optical equipment: • How to clean bare fiber ends • How to clean large area lenses and mirrors How to clean bare fiber ends Bare fiber ends are often used for splices or, together with other optical components, to create a parallel beam. The end of a fiber can often be scratched. You make a new cleave. To do this: 1 Strip off the cladding.
Cleaning Information Additional Cleaning Information Only use water if you are sure that there is no other way of cleaning your optical device without causing corrosion or damage. Do not use hot water, as this may cause mechanical stress, which can damage your optical device. Ensure that your liquid soap has no abrasive properties or perfume in it. You should also avoid normal washing up liquid, as it can cover your device in an iridescent film after it has been air dried.
