Live Optical Fiber Detector When maintaining and installing wiring, it is often necessary to find and separate a specific optical fiber without interrupting the work. By putting 1310nm at one end or 1550nm signal with modulation tone (270Hz, 1 kHz, 2kHz), the signal is sent into the optical fiber and identified on the line with a recognizer to the effective direction. Hanchen Optical Fiber Identifier Optical fiber identifier with red light source is a kind of optical fiber maintenance necessary tools for lossless optical fiber identification work. The red light source can be used to test the light transmission of the optical fiber line. Any position of single-mode or multi-mode optical fiber can be detected. The relative power is displayed by digital. There is no need to interrupt the light source during on-line test. Identify 270Hz, 1kHz, 2kHz modulation signals. Operation mode: simple, quick and convenient. Battery power display function, can clear the state of power at any time. Four in one universal fixture, no need to replace during on-line test. Clamp to ensure no damage to the fiber. Applicable Optical Fiber Product Description Put the fiber into the adapter slot and tighten the snap down.When the light signal passes through the optical fiber, the LED indicator will light up. It shows the direction of the light source and also shows the relative power on the display screen.If there is no light signal passing through the fiber, the LED will be on and the Lo will be displayed6.Press the VFL key to turn on the red light source switch. Press the key again, the switch will be between on 1Hz flashing and off.After 10 minutes of timeout, there is no key response, and the optical fiber identifier will shut down automatically.Automatically disconnect the power supply and prolong the battery life of the optical fiber detector. Features of the optical fiber identifier Three signals can be identified The optical fiber identifier is used for identifying 3 commonly used signal frequencies, namely 2KHz, 1KHz, 270Hz; when the frequency is recognized, it will beep. Hidden red light source The bottom cover of the optical fiber identifier can be opened. The stable and powerful concentrated hidden red light source effectively cooperates with the optical fiber inspection. Ergonomic design When holding the optical fiber identifier, hold the trigger switch on the back with your index finger. Clamp the optical fiber to automatically start the test. Press down to clamp the optcal fiber. Function buttons The live optical fiber detector has two kinds of unit switching: db, dbm; the LED light on the screen can also be switched on and off. The third button is for the red light source.
