The 11th China optical fiber sensing academic conference and industrialization forum officially opened on April 26, 2019, at the optical fiber sensing technology research center of Wuhan University of technology. Nearly 500 scientific and technological workers from universities, research institutes, and related enterprises attended the event. The conference mainly focused on applying optical fiber sensing technology in electric power, petroleum, chemical industry, construction, transportation, medical and environmental protection. It carried out nearly 100 academic reports and technical exchanges. It fully shows the remarkable achievements and progress in optical fiber sensing in China in recent years.

   Beijing conquers Optoelectronic Technology Co., Ltd., as an excellent integrated optoelectronic module supplier in the field of optical fiber sensing, was invited to attend the meeting and sponsored it. With more than ten years of technology accumulation and innovation in the industry, conquer optoelectronics has launched high-performance products in the light source: optical amplification, electro-optical modulation, photoelectric detection, and other technical fields, and has been unanimously praised by customers. At this meeting, conquer optoelectronics mainly exhibited the sweep laser module, broadband light source, erbium-doped fiber amplifier, electro-optical modulation module, photoelectric detection module, and fiber delay module, attracting many representatives.

Among them, the most concerned top 3 products are: 1. Photoelectric detection module; 2. Optical fiber delay module; 3. Erbium-doped fiber amplifier.

1.     photoelectric detection module

   A photoelectric detection module is an indispensable unit in the optical fiber sensing system. The photodetectors independently developed and produced by conquering photoelectric mainly include pin photodetectors: pin photodetectors with amplification, high sensitivity Avalanche Photodetectors, balance photodetectors, multichannel photodetectors, and other products, etc. The detection bandwidth is from DC to GHz, which can fully meet the needs of different optical fiber sensing systems.

2.     high-precision optical fiber delay device

In the past few years, the high-precision optical fiber delay device mainly depends on imports, which increases the system cost. In recent years, through independent research and development, conquer optoelectronics has developed optical delay products of 300ps, 600ps, and 1000ps. The delay accuracy can reach the FS level, which has high integration and low cost. It adopts electric control, internal integration of high-precision motor, and position sensor, providing accurate delay control. It not only facilitates system integration but also saves system costs.

3.    Erbium-doped fiber amplifier

      The backscattered light signal is feeble in the distributed optical fiber sensing system, so it is necessary to amplify the light pulse before the sensor. The erbium-doped fiber amplifier is the most effective technical means to solve this problem. Whether in the field of communication or optical fiber sensing, optical fiber amplifier technology has been mature, and there are many products. The optical fiber amplifier module independently developed by conquering optoelectronics has the characteristics of low power consumption, small size, and customization, which has attracted the attention of medical researchers in the field. At present, the product has served nearly 100 universities and scientific research institutes.
