Detailed Introduction
Fibot-DD-02 belongs to the category of fiber Bragg grating interrogators, and is mainly used to read changes in the reflected optical signal of FBG sensors and convert wavelength changes into usable monitoring data. Its operating wavelength range is 1510–1590 nm, with a span of 80 nm, and a single channel can connect more sensors in series; resolution 1 pm, repeatability ≤2 pm, dynamic range 40 dB, scan frequency 1 Hz, built-in absolute wavelength reference, suitable for industrial and engineering scenarios that require demodulation accuracy and long-term stability. The device provides three specifications: 4-channel, 8-channel, and 16-channel, and comes with host computer software, making it convenient to expand channels according to project scale. For specific price, delivery time, packaging, and certification information, please contact us to confirm; we will assist with model selection and quotation based on the number of channels, number of sensors, and on-site conditions.

Applications
- Industrial high-precision inspection: in production lines or equipment monitoring, read FBG sensor wavelength changes to determine the status of the object being measured
- Engineering sensing monitoring: in engineering scenarios such as bridges, tunnels, and slopes, paired with FBG sensors for long-term signal acquisition
- Multi-channel FBG monitoring: when there are many monitoring points, choose an 8-channel or 16-channel model to reduce the coverage pressure on a single device
- Broad-spectrum signal demodulation: for projects that need to cover multiple FBG wavelengths within the 1510–1590 nm range
- Scientific research and experimental platforms: when 1 pm resolution and ≤2 pm repeatability data are needed for experimental records and comparative analysis
Procurement & Delivery
Before purchasing, we recommend confirming three things first: how many channels are needed, how many FBG sensors are expected to be connected in series per channel, and whether the sensor wavelengths fall within the 1510–1590 nm range. After confirming this information, we can help determine whether a 4-channel, 8-channel, or 16-channel model is more suitable. For price, delivery time, packaging method, and minimum order quantity, please contact us to confirm; we will provide corresponding explanations based on the project quantity and delivery location.
Service & Support
We provide support for selection communication, channel configuration confirmation, and host computer software usage. If you already have an FBG sensor list or the number of monitoring points, you are welcome to provide it to us, and we will help confirm the channel configuration and expansion method of the Fibot-DD-02. Regarding installation conditions, software integration, and subsequent maintenance, please also contact us to confirm the specific arrangements.
FAQ
What channel specifications does this demodulator have?
It is available in three specifications: 4-channel, 8-channel, and 16-channel. You can choose the appropriate number of channels based on the number of monitoring points and the number of sensors connected in series per channel. Welcome to contact us for assistance with model selection.
What are the resolution and repeatability respectively?
The resolution is 1 pm, and the repeatability is ≤2 pm. These two indicators are suitable for monitoring projects that need to distinguish small wavelength changes.
Is software included?
It comes with host computer software, making it convenient to read and record demodulation data. Regarding software integration and specific functions, please contact us for confirmation.
How are the price and delivery time confirmed?
The price and delivery time need to be confirmed based on information such as the number of channels, the number of sensors, and the project location. Welcome to contact us, and we will assist with quotation and delivery arrangements based on your project requirements.
