The KFI-40 Fiber Identifier is a versatile and essential tool for fiber optic network maintenance, designed for non-destructive fiber identification. It integrates multiple functionalities, including fiber identification, a Visual Fault Locator (VFL), and LED lighting, making it suitable for a wide range of field applications.

Function Description:

The primary function of the KFI-40 is to identify optical fibers without interrupting service. This is crucial during maintenance, installation, wiring, and recovery processes where continuous operation is required. To achieve this, a modulated signal (270Hz, 1KHz, or 2KHz) at 1310nm or 1550nm is injected into one end of the optical fiber. The KFI-40 then detects this signal on the line, indicating the presence of a signal and its direction.

The device features an LCD display that shows the power value and frequency of the detected signal. If a signal is present, left and right direction lights illuminate to indicate the signal flow. If no signal is detected, the LCD displays "LO," and the direction indicator lights may flicker. The device also provides an audible buzzing sound when a signal frequency (2KHz, 1KHz, 270Hz) is correctly identified, although this sound may not occur if the signal is too weak. It's important to note that the KFI-40 does not specify power accuracy and should not be used to determine the actual signal strength in the fiber.

In addition to fiber identification, the KFI-40 incorporates a Visual Fault Locator (VFL) function. This VFL uses a 2.5mm universal interface and provides an output power of up to 1mW. It can detect fiber breaks or sharp bends within a range of 3-5km. The VFL supports both continuous wave (CW) and pulsed output modes. To use the VFL, the user turns on the power, opens the dust cover, inserts the fiber into the laser connector, and presses the VFL button. A short press toggles between CW, pulsed output, and off.

The device also includes an integrated LED lighting function, which is useful for working in dark environments. To activate the flashlight, the user turns on the power, opens the dust cover, and presses the "--" button. A short press of the "--" button turns the flashlight off.

• Backlight Display: The LED backlight display enhances visibility in various lighting conditions, eliminating the need for auxiliary lighting.
• One-Touch Operation: The device supports online testing with a simple one-touch operation mode, making it convenient for field use without interrupting business.
• Direction Indicator: Clear left and right direction lights indicate the optical fiber light source direction.
• VFL Key: A dedicated VFL key allows users to easily turn the VFL function on or off.
• Backlight Key: A dedicated backlight key allows users to switch the backlight function on or off.
• Lock Button: A lock button secures the fiber in place during testing.
• Plunger Detachable: The plunger is detachable and can be used on both the front and back of the device, with corresponding surfaces chosen based on the fiber thickness.
• Dust Cover: The built-in dust cover protects the VFL interface and LED lighting.

Maintenance Features and Important Considerations:

• Cleanliness: Equipment should be kept free of dirt and other contaminants to ensure optimal performance.
• Storage: Avoid storing the product in high-temperature environments, strong light, strong magnetic fields, or other harsh conditions such as near fire sources.
• Proper Fiber Handling: Users must carefully place the optical fiber in the provided optical fiber slot. Incorrectly pressing the optical fiber into the head assembly or misalignment with the fiber groove may cause deformation of the optical assembly.
• Eye Safety: Never directly look at the optical output of fiber optic network equipment, test equipment, jumpers, or test jumpers to prevent serious eye injury.
• Physical Protection: Avoid strong physical impacts, including knocking, throwing, trampling, or squeezing the device.
• No Disassembly: Non-professionals are strictly prohibited from disassembling this product.
• Altitude: The device is designed for operating environments at altitudes below 2000m above sea level.
• Battery: The device is powered by two AA batteries.
• Package Contents: The standard package includes the host unit, a packing carton, a certificate, and an instruction manual.

The KFI-40 Fiber Identifier is a robust and user-friendly device that streamlines fiber optic network maintenance by providing reliable identification, fault location, and convenient illumination in a single, portable unit.
