The OFI 400 model is the next generation of Noyes Optical Fiber Identifiers. It has all the features of the OFI 200 model plus an easy-to-read LCD display with Backlight, multiple [TONE] signal detection (270 Hz, 330 Hz, 1000 Hz, or 2000 Hz), power saving feature, and [Set Reference] feature.

  • Page 13: Section 2: Functional Description

    Section 2: Functional Description OFI 200 Model Features The OFI 200 is powered by a standard 9 volt alkaline battery that typically provides over 10,000 operations. Power is controlled by the clamping trigger located on backside of the instrument. The OFI 200 operates only when the trigger is engaged. This ensures extended battery life and minimizes ambient light influence.

  • Page 25: Identifying Tone On Fibers

    Identifying Tone on Fibers During installations, maintenance, rerouting, or restorations it is often necessary to isolate a specific fiber from a bundle without disrupting service. By simply clamping the OFI 200 or OFI 400 onto a fiber before making any cuts, the identifier will indicate if there is [TRAFFIC], [TONE], or [NO SIGNAL] and display the detected [TRAFFIC] signal direction.
  • Page 26 5 When a [TONE] signal is detected, the OFI 400 will produce the continuous “beep” signal and show the [TONE] frequency value on the display. Important: The displayed level measurements (dBm) on the OFI 400 are strictly dependent upon the amount of signal striking the photodiodes in the detector head. Light reaching the detector head is dependent on fiber coating color, coating thickness and link under test -88.8...
