C-LIGHT Fixed Attenuator is a passive optical component with a predetermined attenuation value, designed to reduce optical signal intensity to a stable target level. By providing fixed optical loss without dynamic adjustment, it is suitable for signal level matching, system calibration, receiver protection, and fiber-optic testing. C-LIGHT provides SC/UPC, LC/UPC, FC/UPC, and ST/UPC configurations with MM/SM options for different fiber optic applications.
The Fixed Attenuator provides a predetermined attenuation value, such as 3dB or 10dB, for applications requiring stable and repeatable optical power reduction.
The attenuator operates as a passive component without requiring external power or electronic control, providing a simple solution for fixed optical loss.
The fixed attenuation design provides consistent optical signal reduction for systems where the required attenuation does not need to change during operation.
C-LIGHT provides SC/UPC, LC/UPC, FC/UPC, and ST/UPC configurations for compatibility with different fiber optic interfaces.
MM/SM options support different fiber transmission systems and allow the attenuator to be selected according to the optical network configuration.
The straightforward passive structure offers a practical and economical solution for optical links that require a fixed attenuation level without dynamic adjustment.
The SC/UPC configuration provides fixed optical attenuation for compatible single-mode and multimode fiber optic systems.
The compact LC/UPC configuration is suitable for optical equipment and fiber links using LC interfaces where stable attenuation is required.
The FC/UPC configuration provides a stable attenuation interface for fiber communication systems, optical testing equipment, and compatible network components.
The ST/UPC configuration supports fixed attenuation applications using ST fiber optic interfaces in compatible communication and testing systems.
A Fixed Attenuator introduces a predetermined amount of optical loss into the fiber link to reduce the intensity of the transmitted optical signal. Its internal attenuation structure is designed to provide a stable reduction in optical power. Unlike an adjustable or variable attenuator, the attenuation value is selected before deployment and remains fixed during normal operation.
The attenuation value determines how much optical power is reduced. Common values include 3dB, 5dB, 10dB, and other application-specific levels.
Insertion loss is an important parameter when evaluating the total optical loss introduced by the attenuator and its effect on the overall fiber link.
The attenuator should be matched with the appropriate single-mode or multimode fiber system to ensure suitable optical performance.
SC/UPC, LC/UPC, FC/UPC, and ST/UPC configurations provide different interface choices for integration with existing optical equipment.
The Fixed Attenuator reduces excessive optical power and helps maintain the signal level within the acceptable operating range of optical receivers.
Fixed attenuation can be introduced when the optical power of a transmitter needs to be matched with the input requirements of downstream equipment.
Known attenuation values can be used during optical system calibration and performance verification to create repeatable optical loss conditions.
Fixed attenuators provide controlled optical loss for testing fiber links, transceivers, receivers, and other optical communication components.
When optical input power is higher than the recommended receiver range, a suitable fixed attenuation value can help reduce the incoming optical power.
The attenuator can be integrated into telecom, data communication, and other fiber-optic systems where stable optical power reduction is required.
A Fixed Attenuator provides one predetermined attenuation value, while an Adjustable Attenuator allows the attenuation level to be changed according to system requirements.
The fixed design is suitable for optical links where the required attenuation remains constant during normal system operation.
Adjustable attenuators are more suitable when different optical loss conditions need to be simulated, while fixed attenuators provide repeatable predefined loss.
Fixed attenuation provides a straightforward passive solution when no dynamic optical power adjustment is required.
Fixed Attenuator and MVOA serve different optical power control requirements. A Fixed Attenuator provides a predetermined and stable attenuation value, while MVOA uses mechanical adjustment to vary the attenuation level. Fixed Attenuator is therefore better suited to stable optical links and predefined loss requirements, whereas MVOA is more suitable for applications that require flexible attenuation adjustment during testing, calibration, or system operation.
SC/UPC, LC/UPC, FC/UPC, and ST/UPC configurations provide flexible options for different optical network interfaces.
The available MM/SM configurations support both multimode and single-mode fiber applications.
The predetermined attenuation design provides consistent optical signal reduction for applications that do not require dynamic adjustment.
Fixed attenuation values provide repeatable optical conditions for network testing, equipment calibration, and optical component evaluation.
