Cold Connection Tool 50mW Red Light Pen TM191 Factory Direct Optical Fiber Light Pen Red Light Source Fiber Tool ,Test Precision

TM191 pen-type red light source is a 650nm semiconductor special as the light-emitting device (uncommon LED), driven by a constant current source, emits stable red light, and enters the single-mode (or multi-mode) fiber with the optical interface connection port, through observation The red light overflow point finds the light leakage or bending point, and the point realizes the optical fiber fault detection function.

It is an indispensable tool for optical fiber engineering construction, optical fiber network maintenance, optical device production and research.
