  • Page 39: Cleaning Instructions

    If you are unsure of the correct cleaning procedure for your optical device, we recommend that you first try cleaning a dummy or test device. Agilent Technologies assume no liability for the customer’s failure to comply with these requirements. Cleaning Instructions for this Module The Cleaning Instructions apply to a number of different types of Optical Equipment.

  • Page 40: Why Is It Important To Clean Optical Devices

    Cleaning Instructions Cleaning Information Why is it important to clean optical devices ? In transmission links optical fiber cores are about 9 µm (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 41: What Do I Need For Proper Cleaning

    • Pipe cleaner • Compressed air Dust and shutter All of Agilent Technologies’ lightwave instruments are delivered with caps either laser shutter caps or dust caps on the lightwave adapter. Any cables come with covers to protect the cable ends from damage or contamination.
  • Page 42 Cleaning Instructions Cleaning Information Do not use any other solvents, as some may damage plastic materials and cladding. Acetone, for example, will dissolve the epoxy used with fiber optic connectors. To avoid damage, only use isopropyl alcohol. Cotton swabs We recommend that you use swabs such as Q-tips or other cotton swabs normally available from local distributors of medical and hygiene products (for example, a supermarket or a chemist's shop).
  • Page 43 Cleaning Information Cleaning Instructions Only use pipe cleaners on connector interfaces or on feed through adapters. Do not use them on optical head adapters, as the center of a pipe cleaner is hard metal and can damage the bottom of the adapter. Your pipe cleaner should be new when you use it.
  • Page 44 Cleaning Instructions Cleaning Information Ultrasonic bath Ultrasonic baths are also available from photography or laboratory suppliers or specialist mail order companies. An ultrasonic bath will gently remove fat and other stubborn dirt from your optical devices. This helps increase the life span of the optical devices. Only use isopropyl alcohol in your ultrasonic bath, as other solvents may damage.

  • Page 45: Preserving Connectors

    Keep the caps on the equipment always when it is not in use. All of Agilent 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 Agilent Technologies Sales/Service Office.

  • Page 47: How To Clean Connectors

    Cleaning Information Cleaning Instructions How to clean connectors Cleaning connectors is difficult as the core diameter of a single-mode fiber is only about 9 µm. 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 48: How To Clean Connector Interfaces

    Cleaning Instructions Cleaning Information How to clean connector interfaces Be careful when using pipe-cleaners, as the core and the bristles of CAU T ION the 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 49: How To Clean Bare Fiber Adapters

    Cleaning Information 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 CAU T ION solvents can damage the foam inside some adapters.

  • Page 50: How To Clean Instruments With A Fixed Connector Interface

    Cleaning Instructions Cleaning Information 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 51: Additional Cleaning Information

    Cleaning Information Cleaning Instructions Additional Cleaning Information The following cleaning procedure may be used with other optical equipment: 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.
