Fixed optical attenuator and variable optical attenuator are the two types of fiber optic attenuator. The core difference between fixed and variable attenuator lies in whether the attenuation loss value is adjustable. Detailed comparison is as follows:
1. Attenuation Characteristics
Fixed optical attenuator: Provides a preset fixed attenuation value (e.g., 1dB attenuator, 5dB attenuator, or 15dB attenuator), which cannot be adjusted.
Variable optical attenuator: Supports manual or mechanical adjustment of the attenuation loss (e.g., 0-60dB or 0-40dB Range), suitable for dynamic power control.
2. Application Scenarios
Fixed optical attenuator: Used for stable attenuation requirements, such as fiber optic testing and power balancing.
Variable optical attenuator: Suitable for scenarios requiring frequent adjustments, such as optical device calibration and system debugging.
3. Optical Attenuator Price and Complexity
Fixed optical attenuator: the optical attenuator price is lower then voa attenuator, and structure is simple.
Variable optical attenuator: the variable optical attenuator price is higher, but it offers greater flexibility.
