This advanced 650nm red laser diode made fiber optic detector gets much similar structure as a red laser pointer. However, it gets both continuous wavelength and pulse beam emission modes. In front part of fiber visual fault locator, it is designed with simple pressing on/off button. Users always need to make very slight press of the button, which cannot only make fiber testing pen power off or on, and change of laser beam emitting mode so as to fulfill different type fiber testing efficiently.
In real fiber testing work, fiber optic detector is not used as a presentation tool as a red laser pointer. On contrary, it just gets different application in advanced fiber bending test, fiber break, fiber connector testing works etc. According to exact work distance, this fiber visual fault locator should be selected with different output power so as to get quite satisfied fiber identification accurately.
This fiber optic detector is mainly workable for onsite fiber construction and fiber maintenance works. Owing to extremely deep laser beam penetration ability as deep as 3mm fiber optic layer, red laser beam emission from fiber testing red laser pen can easily reach tested fiber optic fault places. In the tail part of fiber optic visual fault locator, it can be easily inserted with 2 pieces of AAA batteries or AA batteries. Only after batteries are inserted with correct direction, this fiber testing red laser pen begins to work immediately.
In order to make fiber optic detector workable for multiple type fiber optics, it is just selecting standard ST, SC, FC universal fiber connector, which just gets wonderful fiber bending or break identification for various single mode or multi mode fibers wonderfully. The 2.5mm universal adapter has just made this fiber testing 650nm red laser pen workable for all fiber maintenance and fiber construction for all fiber engineers.
