Figure: Pu Niu high performance DAS products and their application

In this exhibition, Pu Niu Technology emphasizes the dual advantages of the advanced nature and reliability of its HiFi-DAS products. By connecting the product to a 90 km bare fiber disk, the company simulated the long-distance monitoring operation environment, and demonstrated the precision detection of vibration signals and the high-fidelity sound restoration effect of DAS products. According to the company’s field personnel, in the real scenario application, the product is generally deployed in the customer’s computer room, connected to the existing optical cable infrastructure, can be continuously monitored along the optical cable, the transmission link is basically maintenancefree, since the project has been put into operation, the product has a high reliability of nearly 50,000 hours.

In the sensitivity detection experiment of underwater acoustic listening in a base sea area, Pu Niu Technology HiFi-DAS has achieved the first place, and there are other 3 domestic and foreign advanced DAS equipment participating in the experiment. In task 1, only the company’s DAS products receive all single frequency and sweep frequency signals; In Task 2, the company’s equipment continued to receive a signal at 107 km in the direction of the vertical fiber, while other manufacturers’ equipment could not detect a signal at 30 km. Pu Niu Technology said that the achievement was mainly due to the company’s profound scientific research accumulation and the technical strength of multi-disciplinary integration such as optical structure, high-frequency signal processing and large model algorithm.

1746SC-INO4I Liang Qilin, general manager of Pu Niu Technology, said: “The accelerated application of artificial intelligence makes optical fiber sensing applications not only ‘audible’, but also ‘accurate’. Since its inception, Pu Niu Technology has adhered to the parallel research of advanced instruments and advanced algorithms, and has accumulated many scientific research achievements from specific technical points to the entire technology chain, so as to successfully develop high-performance DAS products. In the tide of national defense information construction, the company will continue to uphold the concept of scientific and technological innovation, and is committed to providing customers with more high-performance and highly reliable equipment.”

With the wonderful performance in CNTE, Pu Niu Technology has once again proved the leading position of domestic instruments in the field. Looking to the future, we have reason to expect that many domestic high-end equipment manufacturers will continue to deepen technology research and development, take innovation as the engine, drive the development of the industry, and contribute more to national security and information construction.
