Optical Fiber Identifier-(DT-Fl8307)


Optical Fiber Identifier can quicklyidentify the direction of transmitted fiber and display the relative core powerwithout any damages to the bendedfiber. When the traffic is present,the intermittently audible tone is activated.



  Easy-to-use with “ONE KEY” operation.

  Efficiently identifies the trafficdirection and frequency tone (270Hz, 1KHz, 2KHz) with audible warning.

  Displays the relative core power

  More accurate test with Sunshade

  Easy-to-replace adaptors

  Durable metal housing and qualityconstruction

  Lower power indication
