The system can monitor the operation of multiple optical fiber time transfer equipment at the same time. And it can collect data and report them to the network management center for storage, processing, and analysis. Furthermore, this paper studies and analyzes a variety of networking methods of optical fiber time transfer system to provide a guarantee for a safe and reliable timing service system. This paper takes an optical fiber time transfer equipment as an example to realize the data reporting of the equipment between stations to the data monitoring center, combined with the Ethernet communication mode and the Modbus protocol. And the system is characterized by adding the SM4 encryption algorithm, which has the function of security encryption and ensures the security of data transmission. The system will greatly save labor costs and improve the operation and maintenance efficiency of the project at optical fiber time transfer in the future.","PeriodicalId":350271,"journal":{"name":"2022 20th International Conference on Optical Communications and Networks (ICOCN)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116765909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the inconsistency of the sensor sampling frequency and time-delay characteristics, the measured value sequences of the sensor to be calibrated and the reference sensor often have time misalignment, which will have a great impact on the calibration results of the sensitivity coefficient of the FBG sensor. In this paper, classical cross-correlation, wavelet cross-correlation and dynamic time warping algorithm are used to perform data matching. By using a cantilever beam to simulate a bridge structure, the data matching of dynamic strain data of FBG sensor and resistance strain gauge is carried out. The experimental results show that the dynamic time warping algorithm effectively solves the problem of time dislocation of sensor data, and the data matching effect is the best.","PeriodicalId":350271,"journal":{"name":"2022 20th International Conference on Optical Communications and Networks (ICOCN)","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125022634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 1573nm cw distributed feedback (DFB) laser was employed for a strong CO2 absorption line in the near-infrared band. We characterized the effects of plano-convex lens and incident high reflective mirror on fundamental mode matching of the cavity and calibrated the CRDS with several CO2 standard gases. The experimental results showed that the sensor had a good inverse proportional relationship between the ring down time and the concentrations of CO2 standard gases in the range of Oppm to 500ppm, and an optimum detection limit of 6.6ppm could be achieved for carbon dioxide with a 2s integration time.
