MAY45 Fiber Optic Identifier for 250um bare fiber/0.9mm/2.0mm/3.0mmw with 10mW Visual Fault Locator and OPM


SKU: 11015 Category:

MAY45 Optical Fiber Identifier can quickly identify the direction of transmitted fiber and display the relative power without any damages to the bending fiber. When the traffic is present, the intermittently audible tone is activated.
MAY45 Optical Fiber Identifier can also recognize the modulation of 270Hz,1kHz and 2kHz. When they are used to detect the frequency, the continuously audible tone is activated.
The housing of MAY45 Optical Fiber Identifier is made of ABS plastics.
It has Visual Fault Locator for broken fiber location and Optical Power Meter for accurate optical power testing, integrated with MAY45 Optical Fiber Identifier.


  • VFL included
  • OPM included
  • Lower power indication
  • Displays the optical power
  • Suitable for both SM and MM fibers
  • Online testing without interruption of service
  • Easy-to-use with “ONE KEY” operation
  • No need to replace adapters when testing 250um bare fiber, 900um, 2MM and 3MM cables
  • Efficiently identifies the traffic direction and frequency tone (270Hz, 1KHz, 2KHz) with audible warning
