Key Features

  • High-intensity LED indication of active signal transmission.
  • Interchangeable adapter heads for jacketed, coated or ribbon fiber.
  • Low battery indication.
  • Operates using one hand.


  • Operates from 850-1700 nm.
  • Compatible with most AT&T and Corning optical fiber.
  • Uses non-destructive, macro-bending technology.
  • Detection sensitivity of -40 dBm.
  • Bi-directional traffic indication.


  • Live fiber identification.
  • Core power measurement and display on a 2-digit LED display (FI-11).
  • 270 Hz, 1000 Hz, and 2000 Hz modulated tones detection.
  • Relative zero power reading (FI-11).
  • Power loss through a splice or a connector measurement (FI-11).


The FI-10 and FI-11 Optical Fiber Identifier are rugged, handheld, easy-to-use installation and maintenance instruments that identify optical fibers by detecting the optical signals being transmitted through a singlemode fiber. By utilizing local detection technology (non-destructive macro-bend detection), they eliminate the need to open the fiber at the splice point for identification. This, in turn, eliminates the probability of interrupting service.

Signals detected include continuous wave (CW), live optical transmission, and low- frequency modulated tones at 270, 1000, and 2000 Hz. When traffic is present on the fiber tested, the direction of transmission is indicated by LEDs illuminating on the probe.

When modulated tones are present on the fiber under test, the unit will detect and illuminate the corresponding LED for 270, 1000 or 2000 Hz. The relative core power in the fiber is measured and displayed on a two-digit, seven-segment LED display. This allows for the measurement of power loss through a splice or connector.
