Product Description

DA-FI-01 Optical Fiber Identifier


Dawnergy’s DA-FI-01 Optical Fiber Identifier is an essential installation and maintenance instrument.

By inserting the fiber into its adapter head, DA-FI-01 Optical Fiber Identifier can identify SM optical fibers without any damage by detecting the optical signals being transmitted through them to avoid the opening of the fiber at the splice point for identification and thus avoids the interruption of the service.


In the presence of traffic, the intermittently audible tone is activated. The DA-FI-01 Optical Fiber Identifier also allows relative core power display and identification of the 270Hz, 1 kHz and 2 kHz frequencies. When they are used to detect the frequency, the continuously audible tone is activated. There are four types of adapter heads available: 0.25mm, 0.9mm, 2.0mm, and 3.0mm.



  • Efficiently identifies the traffic direction and frequency tone (270Hz, 1KHz, 2KHz) without any damage of the fibers
  • Displays the core power of the fibers (-40~+0dBm)
  • Easy-to-replace adaptors (0.25mm, 0.9mm, 2.0mm, 3.0mm to match various optical cables)
  • Mechanical damp design of adapter heads to ensure the fiber without damage



  • Maintenance in Telecom
  • Maintenance CATV
  • Test Lab of optical fibers
  • Other Fiber Optic Measurements
