Notes:
1 250 µm coated fiber parameters are specified with OFI plunger in the “250/900/RIB” position.
2mm/ 3mm jacketed fiber parameters are specified with OFI plunger in the “2 mm/ 3 mm” position.
2 Unless noted otherwise, all specifications are typical. Actual results can vary by several dB depending on fiber type, coating mate-
rial, jacket color, jacket hardness, and other factors.
All specifications stated above are as measured at 25°C.
3 [CW] is a light signal that is not modulated.
[Traffic] is a light signal modulated by a random data sequence.
[Tone] is a light signal modulated into a nominal 50% duty cycle square wave.

OFI Optical Fiber Identifiers
Applications
• Live fiber identification - used during
installation, maintenance, rerouting, or
restoration to positively identify fibers
prior to cutting and splicing
• Tone detection
• The OFI 400 models may also be used
for measuring core power or relative
power
