Light Source Introduction


Fiber light source is used to inject light into a fiber optic cable for the purpose of testing its' sensitivity and attenuation. It is designed to cover a variety of wavelength ranges to suit all optical testing needs and usually the optical light sources are used with the fiber optic to test the fiber system loss. Usually the fiber optical light source is used with the fiber optic power meters, they act as the economic and efficient solutions for the fiber optic network works.
