The size of a fiber optic cable isn't just a technical detail; it's a critical factor that defines its performance and suitability for specific applications. From the core to the buffer, every layer contributes to the cable's function, ensuring data is transmitted efficiently, securely, and over. Measure distance: 0-30Km (customizable for longer distances) Number of channels: 1-16 (more channels can be customized) Sampling interval : 1 meter positioning accuracy : ± 1℃ Temperature resolution : 0. 1℃ Single channel measurement time : 2s-15s seconds (depending on the length of the temperature. The DiTeSt Ordinary Temperature Sensing cable is a unique sensor for the evaluation of distributed temperature over several kilometers. For MM fibers, typically a core of 50 µm or 62. 5 µm diameter is chosen, which enables significantly more light to travel in the core than in SM fibers. However, we must recalibrate our device to produce reliab and accurate measurements with a different sensor.
