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.

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

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).

The TFI-40 Fiber Identifier is an essential tool designed for non-destructive fiber identification in both single-mode and multi-mode fibers. It is primarily used during fiber maintenance, installation, wiring, and recovery processes where continuous operation is crucial. The device helps identify and separate specific optical fibers by detecting a 1310nm or 1550nm band modulation signal (270Hz, 1KHz, 2KHz) injected at one end of the fiber. Beyond identification, it also indicates the signal direction, streamlining troubleshooting and setup.

A key feature of the TFI-40 is its integration of a Visual Fault Locator (VFL) red light function and an LED lighting function. The VFL utilizes a 2.5mm universal interface, offering an output power of up to 1mW. This allows for the detection of fiber breaks or sharp bends within a range of up to 5KM. The VFL supports both pulse and continuous wave operation, providing flexibility for various fault-finding scenarios. The integrated LED lighting function is particularly useful for construction and maintenance work in dark environments, enhancing user convenience.

Usage Features:

The TFI-40 is designed for ease of use with several intuitive features:

• LCD Display: Clearly shows power values and detected frequencies.
• Direction Indicator: Visually indicates the direction of the optical fiber light source under test.
• Power Button: Simple on/off control for the device.
• Backlight Function: Allows users to switch the backlight on or off for improved visibility in varying light conditions.
• VFL Key: Dedicated button to turn the VFL function on or off.
• Fiber Signal Recognition: To use, the fiber is placed into the fixture's groove, the button is pushed to lock it, and the fixture cover is installed. If a signal is present, left and right direction lights will indicate the signal direction. If no signal is detected, the LCD will display "LO," and the direction indicator light may flicker. When the fiber is not properly clamped, the direction light may also flicker.
• Frequency Indication: When a signal frequency of 2KHz, 1KHz, or 270Hz is detected, the corresponding indicator light illuminates, accompanied by an audible buzzing sound. Note that if the signal is too weak, it may not be correctly identified.
• VFL Red Light Test: After powering on and opening the dust cover, insert the fiber interface into the laser connector. Pressing the VFL button once activates continuous wave output; pressing it again activates pulse output; a third press turns the VFL function off.
• LED Lighting: With the device powered on and the dust cover open, a short press of the "--" button turns the flashlight on, providing illumination for dark environments. Another short press turns it off.
• Three-in-One Universal Fixture Design: Accommodates a variety of optical fibers, ensuring compatibility and secure clamping.
