There are three types of fixtures, namely 2mm, 3mm,
250/900. According to the type of fiber to be tested,
select the corresponding fixture.

Push the button down to the maximum, place the
clamp on the top of the display, and push in the
clamp from the right side.
The fiber identifier is an essential tool for fiber mainte-
nance. It is used for non-destructive fiber identification.
It can be detected at any position of single-mode and
multi-mode fiber. During maintenance, installation,
wiring and recovery, it is often necessary to find and
separate a specific optical fiber without interruption by
injecting 1310nm or 1550nm signal with modulation tone
(270Hz, 1KHz, 2KHz) into the optical fiber at one end,
and use the identifier on the line to recognize it and it
also can indicate the direction of the signal.
2
If there is a signal in the optical fiber, the left and right
direction lights will show the signal direction, and the signal
strength light shows its strength.
3
If there is no signal in the optical fiber, the signal strength
indicator will display LO, and the direction indicator light may
flicker left and right. When the fiber is not clamped, the
direction light may also flash left and right.
4
When the signal frequency is 2KHz, 1KHz, 270Hz, the
corresponding indicator light is on, accompanied by a buzzer
(when the signal is too weak, it will not be correctly identified).
