  • Page 59: Why Is It Important To Clean Optical Devices

    Cleaning Instructions Why is it important to clean optical devices? In transmission links optical fiber cores are about 9 mm (0.00035") in diameter. Dust and other particles, however, can range from tenths to hundredths of microns in diameter. Their comparative size means that they can cover a part of the end of a fiber core, and as a result will reduce the performance of your system.

  • Page 60: What Do I Need For Proper Cleaning

    • Compressed air Dust and shutter caps All of Keysight Technologies’ lightwave instruments are delivered with either laser shutter caps or dust caps on the light-wave adapter. Any cables come with covers to protect the cable ends from damage or contamination.
  • Page 61 Cleaning Instructions evaporated. You should therefore first remove the alcohol and the dust with a soft tissue, and then use compressed air to blow away any remaining filaments. If possible avoid using denatured alcohol containing additives. Instead, apply alcohol used for medical purposes. Never try to drink this alcohol, as it may seriously damage your health.
  • Page 62 Cleaning Instructions Use only clean, fresh soft tissues and never apply them twice. Any dust and dirt from the air which collects on your tissue, or which has gathered after initial cleaning, may scratch and pollute your optical device. Pipe cleaner Pipe cleaners can be purchased from tobacconists, and come in various shapes and sizes.The most suitable one to select for cleaning purposes has soft bristles, which will not produces scratches.

  • Page 63: Additional Cleaning Equipment

  • Page 64 Cleaning Instructions Warm water and liquid soap Only use water if you are sure that there is no other way of cleaning your optical device without 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.

  • Page 65: Preserving Connectors

    Keep the caps on the equipment always when it is not in use. All of Keysight Technologies’ lightwave instruments and accessories are shipped with either laser shutter caps or dust caps. If you need additional or replacement dust caps, contact your nearest Keysight Technologies Sales/Service Office.

  • Page 66: Cleaning Instrument Housings

    Cleaning Instructions Cleaning Instrument Housings Use a dry and very soft cotton tissue to clean the instrument housing and the keypad. Do not open the instruments as there is a danger of electric shock, or electrostatic discharge. Opening the instrument can cause damage to sensitive components, and in addition your warranty will be voided.

  • Page 68: How To Clean Connectors

    Cleaning Instructions How to clean connectors Cleaning connectors is difficult as the core diameter of a single-mode fiber is only about 9 mm. This generally means you cannot see streaks or scratches on the surface. To be certain of the condition of the surface of your connector and to check it after cleaning, you need a microscope.

  • Page 69: Procedure For Stubborn Dirt

    Cleaning Instructions Procedure for Stubborn Dirt Use this procedure particularly when there is greasy dirt on the connector: Moisten a new cotton-swab with isopropyl alcohol. Clean the connector by rubbing the cotton-swab over the surface using a small circular movement. Take a new, dry soft-tissue and remove the alcohol, dissolved sediment and dust, by rubbing gently over the surface using a small circular movement.

  • Page 70: How To Clean Connector Interfaces

    Cleaning Instructions How to clean connector interfaces Be careful when using pipe-cleaners, as the core and the bristles of the CAUTION pipe-cleaner are hard and can damage the interface. Do not use pipe-cleaners on optical head adapters, as the hard core of normal pipe cleaners can damage the bottom of an adapter.

  • Page 71: How To Clean Bare Fiber Adapters

    Cleaning Instructions How to clean bare fiber adapters Bare fiber adapters are difficult to clean. Protect from dust unless they are in use. Never use any kind of solvent when cleaning a bare fiber adapter as CAUTION solvents can damage the foam inside some adapters. They can deposit dissolved dirt in the groove, which can then dirty the surface of an inserted fiber.

  • Page 72: How To Clean Lenses

    Cleaning Instructions 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.

  • Page 73: How To Clean Instruments With A Fixed Connector Interface

    Cleaning Instructions How to clean instruments with a fixed connector interface You should only clean instruments with a fixed connector interface when it is absolutely necessary. This is because it is difficult to remove any used alcohol or filaments from the input of the optical block. It is important, therefore, to keep dust caps on the equipment at all times, except when your optical device is in use.

  • Page 74: How To Clean Instruments With An Optical Glass Plate

    Cleaning Instructions How to clean instruments with an optical glass plate Some instruments, for example, the optical heads from Keysight Technologies have an optical glass plate to protect the sensor. Clean this glass plate in the same way as optical lenses (see How to clean lenses page 72).

  • Page 75: How To Clean Instruments With A Physical Contact Interface

    Cleaning Instructions How to clean instruments with a physical contact interface Remove any connector interfaces from the optical output of the instrument before you start the cleaning procedure. Cleaning interfaces is difficult as the core diameter of a single-mode fiber is only about 9 mm.

  • Page 76: How To Clean Instruments With A Recessed Lens Interface

    Cleaning Instructions How to clean instruments with a recessed lens interface For instruments with a deeply recessed lens interface (for example the WARNING Keysight 81633A and 81634A Power Sensors) do NOT follow this procedure. Alcohol and compressed air could damage your lens even further.

  • Page 77: How To Clean Optical Devices Which Are Sensitive To Mechanical Stress And Pressure

    Cleaning Instructions How to clean optical devices which are sensitive to mechanical stress and pressure Some optical devices, such as the Keysight 81000BR Reference Reflector, which has a gold plated surface, are very sensitive to mechanical stress or pressure. Do not use cotton- swabs, soft- tissues or other mechanical cleaning tools, as these can scratch or destroy the surface.

  • Page 78: How To Clean Metal Filters Or Attenuator Gratings

    Cleaning Instructions How to clean metal filters or attenuator gratings This kind of device is extremely fragile. A misalignment of the grating leads to inaccurate measurements. Never touch the surface of the metal filter or attenuator grating. Be very careful when using or cleaning these devices. Do not use cotton- swabs or soft- tissues, as there is the danger that you cannot remove the lint and that the device will be destroyed by becoming mechanically distorted.
