And, because of the Agilent 83438A’s rela- tively high power density, the optical spectrum analyzer can sweep much faster than if a white light source, surface emitting LED, or even an EELED were used.

  • Page 27: Ambient Light Suppression

    Ambient light can add significant errors to optical power measurements. This is especially true when you are using or characterizing open beam devices. The following example shows how the combination of the Agilent 83438A and an Agilent 71450/1/2B optical spectrum analyzer can be used to eliminate this error.

  • Page 28: To Suppress Ambient Light

    As shown in the equipment setup drawing, two Agilent 83438As are used. One Agilent 83438A represents the broadband contribution of ambient light. Because a 12 dB coupler is used, the ambient light contributes approximately 10 dB more power to the optical spectrum analyzer than the desired source.

    If no signal is present on the MODULATION INPUT connector, the source is turned on. If you want to turn the output off, simply connect a BNC short to the rear- panel modulation input. You can order a BNC short from Agilent Technologies using the following part number: 1250-0774.

  • Page 31: Cleaning Connections For Accurate Measurements

    Connectors also vary in the polish, curve, and concentricity of the core within the cladding. Mating one style of cable to another requires an adapter. Agilent Technologies offers adapters for most instruments to allow testing with many different cables.

  • Page 34 Making Measurements Cleaning Connections for Accurate Measurements The soft core, while allowing precise centering, is also the chief liability of the connector. The soft material is easily damaged. Care must be taken to mini- mize excessive scratching and wear. While minor wear is not a problem if the glass face is not affected, scratches or grit can cause the glass fiber to move out of alignment.
  • Page 35 Use the following guidelines to achieve the best possible performance when making measurements on a fiber-optic system: • Never use metal or sharp objects to clean a connector and never scrape the connector. • Avoid matching gel and oils. Figure 2-4. Clean, problem-free fiber end and ferrule. Figure 2-5.
  • Page 36 Making Measurements Cleaning Connections for Accurate Measurements Figure 2-6. Damage from improper cleaning. While these often work well on first insertion, they are great dirt magnets. The oil or gel grabs and holds grit that is then ground into the end of the fiber. Also, some early gels were designed for use with the FC, non-contacting con- nectors, using small glass spheres.
  • Page 37 • Keep connectors covered when not in use. • Use fusion splices on the more permanent critical nodes. Choose the best con- nector possible. Replace connecting cables regularly. Frequently measure the return loss of the connector to check for degradation, and clean every connec- tor, every time.
  • Page 38 Cleaning Connectors The procedures in this section provide the proper steps for cleaning fiber- optic cables and Agilent Technologies universal adapters. The initial cleaning, using the alcohol as a solvent, gently removes any grit and oil. If a caked-on layer of material is still present, (this can happen if the beryllium-copper sides of the ferrule retainer get scraped and deposited on the end of the fiber during insertion of the cable), a second cleaning should be performed.
