Product Overview

In traditional Raman optical time-domain demodulation, the resolution in terms of meter-scale spatial sensing has already reached its limit. The sampling rate, signal bandwidth, and narrow pulse accuracy cannot be further improved or surpassed. Bridging technology combines the technology of scattering optical pulse coding with NPU (Neural Processing Unit) hardware decoupling, and has developed a new generation of centimeter-scale distributed fiber optic temperature sensing system. This system has significant implications in the field of fiber optic sensing. The company has independently developed the BLY-FT100 model, which is a complete set of equipment that can be connected to a maximum of 50 km of optical cable. It supports up to 16 channels and achieves a positioning accuracy of ±0.05 meters (5 centimeters). The minimum temperature sensing unit is ±0.05 meters, and the temperature accuracy is ±0.05°C (measured). The measurement time is within 3 seconds. With a 50 km optical cable connected, the main unit of the equipment is equivalent to a real-time load of one million distributed temperature sensors with positioning capabilities. Each fiber optic sensor at 0.05 meters (5 centimeters) has its own position coordinates. It can obtain real-time temperature values of all sensors online and also obtain the position of each sensor. This system can be widely used in applications such as leak location and early warning in oil pipelines, heat location and early warning in power cables, safety location and early warning in coal mines, fire location and early warning in firefighting, and safety location and early warning in new energy, and so on.
