The main customer pain points in the practical application of fiber optic attenuators are concentrated in the following aspects:
1. Lifespan and reliability issues
Environmental sensitivity: The lifespan of attenuation in optical communication is significantly affected by the operating environment, such as temperature, humidity, and vibration, which can lead to performance degradation or damage.
Material aging: After long-term use, the internal materials of the attenuator (such as coatings and connectors) may age, leading to attenuation value drift or increased insertion loss.
2. Price and Cost Pressures
Wide Price Range: Build out attenuators are relatively inexpensive than attenuators variable like MEMS or inline attenuator, which require customers to weigh cost against performance.
Maintenance Costs: Frequent replacement or calibration of attenuators can increase hidden costs, especially in scenarios requiring high precision.
3. Complexity of Parameter Selection
Attenuation Range and Accuracy: Depending on system requirements, users need to select either fixed values (e.g., 1dB, 10dB) or attenuator varialbe from 0dB to 60dB. Improper parameter selection can lead to signal distortion or waste.
Wavelength and Fiber Type Matching: Attenuators in optical communication can use both single-mode and multi-mode fibers, and different wavelengths (e.g., 1310nm/1550nm), must be strictly matched; otherwise, transmission efficiency will be affected.
4. Performance and Functional Limitations
Insertion Loss: Low-quality attenuators may introduce additional loss, affecting the system’s signal-to-noise ratio.
Dynamic Adjustment Capability: Adjustable attenuators need to support fast response (such as dynamic power control in AI networks), but this has a high technical barrier.
5. Supply Chain and Compatibility
Domestic Production Challenges: High-end variable fiber attenuators rely on imports, and domestic alternatives require overcoming technological bottlenecks (such as MEMS technology).
Interface Compatibility: Different connectors (such as SC and LC connector) need to be compatible with existing equipment; otherwise, additional adapters are required.
Conclusion
These pain points require customers to consider cost, environmental adaptability, and technical parameters comprehensively when selecting products to optimize system performance.
