Fiber signal recognition
The fiber identification instrument is an essential tool for
fiber maintenance. 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
continue without interruption. In the case of business, find
and separate a specific optical fiber, by injecting a
1310nm or 1550nm band modulation (270Hz, 1KHz, 2KHz)
signal into the optical fiber at one end, and use the
recognizer to identify it on the line, and it can also indi-
cate the signal direction. This product integrates VFL red
light function and LED lighting function. The VFL uses a
2.5mm universal interface with an output power of up to
1mW, which can detect fiber breaks or corners within
5KM. The VFL red light source supports pulse and contin-
uous wave operation. Equipped with LED lighting function,
convenient for construction in the dark.

Note: This product does not specify power accuracy
and should not be used to determine the actual signal
strength in the fiber.
2.If there is a signal in the optical fiber, the left and
right direction lights show the signal direction.
3.If there is no signal in the optical fiber, the LCD
display shows LO, and the direction indicator light
may flicker left and right. When the fiber is not
clamped, the direction light may also flicker left and
right
4.When the signal frequency is 2KHz, 1KHz, 270Hz,
the corresponding indicator light is on, accompanied
by a buzzing sound (when the signal is too weak, it
will not be correctly identified).
1.Put the fiber to be tested into the groove of the
fixture, push the button to lock the fixture, and
install the fixture cover .
