VIAVI FI-10/-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 single-mode 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.


  • 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.

  • 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).
