FDA 10Km Red Light Pen Style Visual Fault Locator Fiber Optic Cable Tester Pen Laster Tester 1mw

FDA 10Km Red Light Pen Style Visual Fault Locator Fiber Optic Cable Tester Pen Laster Tester 1mw
Product Detailed
High quality! Best price! Fast Shipment!


The product can be used to inspect fiber failure when they connect with optical interface and be inserted into single mode or multi mode optical fiber. It is indispensable tool in fiber project constructing, fiber net-work maintaining, optical component manufacture and research.


High power laser and visible 650nm/635nm red light Anti-collision shell Pen style design to make it easy to carry Continuous light or 2Hz frequency of light output applicable for SM and MM fiber (Single-mode, multi-mode fiber) Universal alkaline battery Continuous working time more than 40 hours Insert the fiber into VFL through Fiber Connector. It can be used as reference of the multi-core cable End to end fiber identification Identify the breaks and micro-bend of the pigtail/fiber OTDR dead zone fault locator: check the fiber fault point which OTDR can't find (breakpoint, the beginning and the end of the fiber properties, and also the high loss section due to the microbending, for example: fiber optic patch cords, pigtails, the optical fiber core wire in junction box or bare fibe, etc Identify the certain distance of fiber according to the power. Such as 10mw pen style VFL can check the distance up to 10kms


This LED indicator shows the following working mode:

1. Screw off the tail, then put two 1.5V batteries into the tail,.(Caution: anode of batteries point to bottom of the locator, cathode of batteries contact cathode of the locator).2. Connect the body with the tail, and open dust cap, then press the switch. You will see the red laser emitting from the optical interface, at the same time, LED will be lighted up (Please don't stare at the beam, for fear of damaging your eyes).3. Press the switch again, light-emitting changes to pulse mode, and LED synchronize with light-emitting (pulse frequency will be controlled at 0.5-2.0 Hz ).4. Press the switch again, the optical source will shut, and there is no more light. Meanwhile, LED put out (Switching cycle mode is: continuous-pulse-shut).5. You should insert the fiber which you want to inspect into optical interface, then press the switch to choose working mode of the light source (continuous or pulse).6. When you finish the inspection, please screw on the dust cap. If you don't use the indicator for a long time, you must take out the batteries, in case that batteries rot and destroy light source.

Maintenance and attentions:1. Laser is harmful, so especially, you must protect your eyes. When the LD working, please don't let your eyes exposure to laser. 2. Generally, the higher is temperature, the shorter is life of the LD. Avoiding high temperature when you use it.3. The head of fiber must cleared up while the LD operates.4. If don't use this light source, please screw on the dust cap in case that the dust fall into.5. Take out the batteries when you don't use it.
