  • Maximum range: 0 to -40 dBm
  • Detection of modulated tones; 270 Hz, 1 kHz, 2 kHz
  • Single-hand operation
  • Light weight (7.5 oz.)
  • Interchangeable head for ribbon, jacketed and coated fiber allows virtually any fiber to be identified


The FI710, part of the FI700 Series of Optical Fiber Identifiers, is the safe, economical and non-destructive way to identify live optical fibers. These rugged units use local detection technology, which employs a macro-bend method, eliminating the need to open the fiber at the splice point for identification.

All models detect continuous wave, live optical transmission and low frequency modulated tones at 270, 1k, and 2k Hz. The presence of traffic, the direction of the transmission and modulated tones on the fiber are indicated by LEDs.
