The price of high-speed Fiber Bragg Grating (FBG) demodulators varies widely depending on channel count, sampling frequency, and manufacturer, typically ranging from several thousand to tens of thousands of USD per unit.

Overview of High-Speed FBG Demodulators

High-speed FBG demodulators are advanced optoelectronic devices used to convert reflected wavelength signals from FBG sensors into precise measurements of strain, temperature, pressure, or displacement. They are widely applied in structural health monitoring, aerospace, civil engineering, energy, and industrial automation . Key features include:

• Multi-channel capability: Devices can support 4, 8, 16, or 32 channels, with some high-end models offering full-channel synchronous acquisition .
• High sampling rates: Refresh rates range from 10 Hz to 100 Hz for standard models, while advanced systems can reach up to 10 kHz for dynamic monitoring .
• High precision: Wavelength resolution can be as fine as 1 pm, ensuring reliable long-term monitoring .
• Software and integration: Many demodulators include browser/server-based software for remote management, IoT integration, and closed-loop control .

Factors Affecting Price

The cost of an FBG demodulator depends on several factors:

1. Channel count: More channels increase hardware complexity and cost.
2. Sampling frequency: Higher-speed demodulators require advanced electronics and lasers.
3. Wavelength range and resolution: Devices with broader spectral coverage or higher precision are more expensive.
4. Software and connectivity: Advanced software ecosystems, cloud integration, and secondary development interfaces add to the price.
5. Customization: Tailored solutions for industrial or laboratory applications can significantly increase cost .
