MAY46 Fiber Optic Identifier for 250um bare fiber/0.9mm/2.0mm/3.0mmw with 10mW Visual Fault Locator and OPM


SKU: 11016 Category:

MAY46 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.
MAY46 Optical Fiber Identifier, using macro-bending technology on line for non-destructive testing, can measure the signal direction and power, and avoid mis-operation result in interrupted lines.
It has Visual Fault Locator for broken fiber location and Optical Power Meter for accurate optical power testing, integrated with MAY46 Optical Fiber Identifier.


  • VFL included
  • OPM included
  • Lower power indication
  • Displays the relative power
  • No need to replace adapter
  • Indicate signal presence or absence
  • Indicate singal direction and power in fiber
  • Efficiently identifies the traffic direction and frequency tone (270Hz, 1KHz, 2KHz) with audible warning.
