Both ends can be connected to the same type of optical fiber connector to realize the optical fiber connection. It is widely used in optical fiber communication, like CATV, LAN, WAN, FTTX etc.
Through attemuator, the optical power can be adjusted to the required intensity. The FO attenuator is usually applied to evaluate system loss and other tests. Both fixed attanuator and variable attemuators available.
The Fiber Bragg Grating (FBG) is an optical component that creates periodic changes in the refractive index within the fiber core through ultraviolet light exposure.
