1, without the need for cell phones and other wireless calls, FF303 fiber sequence finder (signal generator / fiber identification instrument) can be accurately aligned with the specified load signal fiber through the music sound and dynamic image of the field instrument; 2, the motor automatically advances, the bending degree is always kept to a minimum, when no power is detected, the fiber is released; *, the motor automatically advances, the bending degree is always kept to a minimum, when no power is detected, the fiber is released.

2, the motor automatically advances, the bending degree is always kept to a minimum, no damage to the fiber, when no power is detected, the fiber is released; *

3, for most single-mode fiber (most sheath types) and all wavelengths of the signal, can ensure that the loss does not exceed 0.5dB.

4, bend the fiber to cause power changes in the area to locate and real-time online and uninterrupted detection and evaluation of power. 

5, information flow detection and direction identification, using audio identification technology (270Hz, 1kHz and 2kHz) to locate special dark fiber.

6. fast test speed, with the entire process completed in less than 6 seconds.

7, ultra-long distance applications, as long as the optical signal power in the fiber is greater than -35dBm, even ultra-long distance can be measured.

8, for different types (thickness) of optical fiber testing, no need to replace the head fixture, its powerful intelligence will be based on the material and thickness to do adaptive optimization adjustment.

9, will perform ambient light offset before fiber bending, thus reducing the sensitivity to ambient light. Press cap can also be installed to the front end to block strong ambient light interference.

10, with online test line optical power function and through the instrument display window display .
