Latest company news about  optical fiber attenuator

An optical fiber attenuator is an optical device that reduces the energy of an optical signal. It is used to attenuate the input optical power, preventing distortion in the optical receiver caused by excessively high input optical power.

As a passive optical device, optical fiber attenuators are used in optical communication systems to adjust optical power performance, calibrate optical fiber instruments, and attenuate optical fiber signals. The products are manufactured using attenuating optical fibers doped with metal ions, enabling the optical power to be adjusted to the required level.
