Kingfisher KI 9800 Series Optical Light Source

Compact, Consistent, and Reliable Light Source Provides Superior Measurement Confidence


What's special about these pocket sized fiber optic light sources?

  • Available in 2 wavelength models that are designed to be simple to use, these devices help to create a highly productive and stable environment for testing single mode or multimode fiber optic systems.
  • Superior re-connection repeatability (<0.1 dB) for consistent source stability when testing multiple fibers or retesting the same fiber.
  • Compact design is small enough to fit easily into a shirt pocket, while remaining rugged enough to survive a 2 meter drop onto a hard surface.

  • Optional connectors, including LC style, are available separately for use on a wider range of networks and fiber optic cables.
  • Incredibly tough construction provides moisture resistance with rubber corners and captive dust cap that can survive harsh punishment.
  • Connectors are metal-free to avoid contaminating the connectors in high power systems.
  • Up to 35 hours of use from only 2 AAA alkaline batteries, with a low battery indicator for providing reliable service in the field or in the lab.
  • 1310nm - 1550 nm laser source provides the ideal solution for single-mode testing when combined with a compatible power meter
  • 850 nm - 1300 nm LED source provides the ideal solution for multimode testing when combined with a KI 9600 series power meter; the combination features a standards-compliant beam geometry and modal distribution across the fiber core, resulting in better test consistency when different sources are used to test the same sample.
  • IEC, EMC, ICES, and FCC compliant
  • NATAILAC-MRA accredited for world recognized traceable calibration
  • 3 year manufacturer’s warranty


  • SC connector adaptor OPT046 blue or OPT046G green
  • Quick guide
  • 50 & 62.5 µm fiber mandrel wraps OPT701 for LED source
  • Soft carry pouch
