FA-OA-FPFFPF Metal Fixed Type Optical Fiber Attenuator FC Female to FC Female 1-20dB

Fiber optical attenuator is a kind of precision fiber optic device which can provide a certain attenuation according to the needs of engineering. It is used in all kinds of optical fiber transmission lines to reduce the light intensity by a predetermined amount. As a kind of optical passive device, it is used to debug the optical power performance, calibrate the optical fiber instrument, and attenuate the optical fiber signal in the optical communication system. Fiber attenuator is made of attenuation fiber mixed with metal ion, which can adjust the optical power to the required level.

Service conditions of optical fiber attenuator: an optical device used when the input optical power of the optical fiber receiver exceeds a certain range or when measuring the sensitivity of the optical fiber receiver.

Working principle of optical attenuator: it changes the proportion of reflected light and transmitted light by adjusting the rotation angle of the fiber attenuator to change the light attenuation.

Type of fiber optical attenuator: fixed type, step-by-step type, continuously change type and so on.

Relevant reference indexes of the fiber optic attenuator: insertion loss, working wavelength, attenuation accuracy, attenuation variation range, step quantity, etc. to measure the working condition and performance of the optical attenuator.

Composition material: optical fiber attenuator is made of glass sheet with evaporated metal film.
