TFI-40 Fiber Identifier

Upgraded high accuracy fiber identifier TFI-40 integrates VFL and LED lighting function. It is one of the necessary tools for fiber maintenance. Fiber identifier can detect any position of the single mode and multi mode fiber.

With the fiber identifier to identify the fiber on the line, you can identify the fiber power and 3 kinds of signal frequencies, and there will be a buzzer sound when identifying the frequency.Display the signal direction via left and right direction light and to make prompt judgment.VFL adopt 2.5mm universal connector and output power is up to 10mW,It can detect fiber break or bending problems within 10km, and it supports pulse and continuous wavelength operation. And it equipped with LED light, convenient for you to work in the dark.

Products characters and functions:

  • Suitable for 0.25/0.9/2.0/3.0mm fibers.
  • Test sensitivity: -40dBm to 10 dBm.
  • Configure VFL function, 2.5mm universal.
  • Test distance up to 10km, high stability.
  • Be equipped with LED light, more convenient to check the fibers in the dark.
  • LED backlight display, suitable for various environments without auxiliary lighting.
  • Strong light source, strong penetrating power.
  • Easy to carry, no need to replace the chucks.
