FA-OA-FPFFPM, High Return Loss FC/PC Female To FC/PC Male Fiber Optic Attenuator 1 to 30dB

Optical attenuator is a very important fiber optic passive device. It can attenuate the energy of optical signal according to the user's requirements. It is often used to absorb or reflect the optical power margin, evaluate the loss of the system and various tests. At present, fiber optical attenuators have been widely used in the field of optical communication, bringing convenience to users.

Optical attenuator is an optical device that can attenuate the power of an optical signal according to a set requirement by inserting it into the optical path. It can be used to adjust the power of optical signal transmitted by optical communication system or test system, so that the system can work well as expected. It is also commonly used to detect the sensitivity and dynamic range of optical receivers.

Optical fiber attenuator can be divided into fixed attenuator, hierarchical variable attenuator, continuous variable attenuator, continuous and hierarchical combined attenuator and so on. Its main performance parameters are attenuation and accuracy.

Metal films are usually evaporated or sputtered on glass substrates or attenuated by doped glass with high absorption. The required attenuation can be obtained by controlling the coating thickness or the doping amount and thickness of the glass. The optical attenuator can also be made from the coupling loss of two optical fibers docking.
