Different Types of Fiber Optic Attenuators
Fixed Optical Attenuator
Optical Variable Attenuator
Designed to generate an unchanging level of signal attenuation.
Has the stability, wavelength insensitivity, and mode insensitivity that’s helpful during signal testing and measurement.

Gap-Loss Principle
Absorptive Principle
The attenuator is placed in the fiber path together with an in-line configuration to lessen the optical signal produced.
The optical fiber’s capability to reduce optical power by converting the energy it absorbs into heat.
Light reflection Fiber
Light
Fiber cladding
Reflective Principle Attenuators reduce the optical signal by scattering and reflecting the light that passes through it.
