Hello, I would like to inquire about FBG temperature sensing fiber gratings. The tail end is FC/APC, and the existing demodulator interface is FC/APC. The effective wavelength band is designed for 1525–1565 nm. The fiber will be placed in a small groove with a maximum groove length of 63mm. The groove width and depth are tentatively set at 1 mm each. This 63 mm must accommodate the entire FBG measurement point array and necessary internal transition structures, not the center-to-center distance between the first and last measurement points. The highest temperature for measurement is around 160 degrees Celsius, with no requirement for the lowest temperature; room temperature or 0 degrees Celsius is acceptable. The total sensing length is 63 cm. What is the maximum number of measurement points? What is the minimum distance between measurement points?

Hello, we are currently working on a project where we need to route fiber optics from the inside of a transformer oil tank (80~100℃) to the outside. We learned from patent information that your company has specialized fiber optic feedthroughs for oil-immersed transformers, and we would like to inquire about a few key issues: Can your company's fiber optic feedthrough products be immersed in 80~100℃ transformer oil for a long period? Do you have any relevant oil resistance test data or application cases? I need a 6-core fiber optic channel. The fiber type is 105/125μm multimode fiber, and the connector is SMA905. Can your company provide a 6-core integrated flange? Or do we need 6 single-core flanges?

Research and testing are currently underway for flow electrode capacitive deionization (FCDI) devices in water treatment applications. To validate the preliminary fluid simulation model, we need to perform in-situ measurements of flow rate differences in various regions within the device chamber and the pressure difference between the inlet and outlet. After research, I plan to use multi-point capillary fiber Bragg gratings (CapillaryFBG) to pass through the flowing brine chamber for stress/strain detection. Since our operating conditions involve micro-pressure differences and low flow rates, I would like to consult your company's technical experts on whether the current customized FBG products and supporting demodulators can meet the following measurement requirements?
