The FI720, 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. In addition, the FI720 models measure the fiber's relative power and
displays the reading on a two-digit, seven-segment LED. This allows for
measurement of power loss through a splice or connector.
