How do optical attenuators work?

Optical attenuators usually work by absorbing the light, like sunglasses absorb extra light energy. Another type of attenuator utilizes a length of the high-loss optical fiber, that operates upon its input optical signal power level in such a way that its output signal power level is less than the input level.

Why do we need fiber optic attenuators?

Fiber optic attenuators are used in applications where the optical signal is too strong and needs to be reduced. For example, in a multi-wavelength fiber optic system, you need to equalize the optical channel strength so that all the channels have similar power levels.

What was the original name of Volunteers of America?

How do optical amplifiers work?

An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal. In doped fiber amplifiers and bulk lasers, stimulated emission in the amplifier’s gain medium causes amplification of incoming light.
