The offshore operation technology of the oil and gas industry is the key to ensure the smooth development of offshore oil and gas resources.

Optical fiber and cable and oil field sensing technology play a vital role. With its high-speed and large-capacity data transmission capacity, optical fiber and cable provides a stable and reliable communication guarantee for offshore operations. Through optical fiber and cable, the operation platform can obtain the monitoring data of submarine oil and gas Wells in real time to ensure the safety and efficiency of the operation process.

Oilfield sensing technology realizes real-time monitoring and early warning of oil and gas Wells through various sensors arranged on the sea floor. These sensors can sense the key parameters such as pressure, temperature and flow of the wellhead, and provide decision support for operators to work to prevent potential safety risks.

With the continuous development of science and technology, the offshore operation technology is also constantly innovating and improving. In the future, optical fiber and cable and oilfield sensing technology will continue to provide strong support for the deep-sea development of the oil and gas industry, and promote the sustainable utilization of offshore oil and gas resources.

The loss is mainly caused by the scattering and escape of light generated by the fiber during bending.

When the light is transmitted in a curved fiber, part of the light will escape from the fiber due to the changing propagation speed and direction of the light in the medium, thus causing the loss of the optical signal.

In addition, the propagation of light in the optical fiber is through full reflection, and at the bend, the degree of incidence angle of light may exceed the critical angle of full reflection, resulting in scattering phenomenon, which will also cause the loss of optical signal.

The size of the macrobending loss is affected by many factors, including the bending radius, the type and material of the fiber, and the outer coating of the fiber. A smaller bending radius will increase the scattering and escape of light, resulting in increased macrobending loss.

The special outer coating can reduce the scattering and escape of light, thus reducing the macrobending loss.

Optical fiber hydrophone system is a complex sensing system, which mainly uses optical fiber sensing technology to realize the conversion, transmission and processing of underwater sound signals. As the core part of the system, the implementation process are crucial to the performance of the whole system.

 The components of optical fiber hydrophone mainly include wet end and dry end. The wet end, as the sensing end, consists of the optical fiber hydrophone sensor probe and the transmission optical cable used to transmit the optical signal. The sensor probe is the core component of fiber-optic hydrophones, which can receive underwater sound signals and convert them into optical signals.

The dry end mainly includes the light source of optical fiber hydrophone, optical passive device, photoelectric conversion module and signal demodulation processing module. The light source is responsible for providing stable optical signals. The optical passive device is used to control the transmission and modulation of the optical signal. The photoelectric conversion module converts the received optical signal into an electrical signal, and the signal demodulation processing module demodulates and processes the electrical signals to extract useful sound information.

 With the continuous development of science and technology, the use of electric power electrical equipment safety has been constantly concerned. Optical fiber temperature measurement in the power system and oil and gas pipeline application range gradually into people's vision, but for the operation principle we know little, the following to introduce the principle of fluorescent fiber temperature measurement, distributed fiber temperature measurement principle, fiber grating temperature measurement principle. Optical fiber temperature measurement can not only be used in the field of electric power, petroleum and petrochemical, but also in the field of scientific research and experiment.

Based on the fluorescence lifetime of the temperature measurement of the optical fiber, generally speaking, the outer electrons of the fluorescent material molecules are in a relatively stable state, when the excited light is illuminated, the electron absorption energy transition will appear. After the excitation light disappears, it is allowed to return to the ground state, but the energy keeps radiating, creating fluorescence. For its specific temperature measurement, the temperature of the material surface is related to the decay of the fluorescence afterglow itself, and the so-called afterglow decay is actually the fluorescence lifetime. There is a direct relationship between the length of the fluorescence lifetime and the temperature. After the temperature of the fluorescent substance is determined, the actual afterglow retention time is the lifetime, which itself is monotonous with the current signal. Therefore, through the characteristic curve, the corresponding material can be selected as the probe, and through the relationship between the detected current value and the time stent, the surface temperature can be clearly defined, and then the temperature of the monitoring point can be determined. In the project implementation, compared with the normal operating temperature detection, the temperature after the failure increases abnormally, so the detection significance is greater.

Endoscope, an examination device that can directly enter the natural human cavity, provides doctors with sufficient diagnostic information to treat the disease. There are many kinds of endoscopy, including gastrointestinal endoscopy, thoracic laparoscopy, tracheoscopy, hysteroscopy, ureteroscopy, etc. Different kinds of endoscopes, applied in different departments. Gastroenterology department, cardiothoracic surgery department, urology department, gynecology department, respiratory department and other departments, all need to use medical endoscopy for diagnosis or treatment.

However, the traditional endoscope structure is complex and difficult to thoroughly clean and disinfect. The application of the same endoscope between different patients can easily lead to cross-infection, which can cause serious damage to the health of the infected person and even death.

After years of exploration by endoscope enterprises, the disposable endoscope is on the "stage". Its appearance effectively solves the problem of cross-infection, and there is no loss of endoscope for disposable use, which can ensure that each unpackaging endoscope is in the best state, and improve the surgical efficiency to a certain extent. In addition, disposable endoscopy can also enable hospitals to effectively control the cost related to endoscopy, and promote the promotion of endoscopic surgery in primary hospitals.

The clinical application of medical endoscopy technology mainly focuses on diagnosis and treatment. Through different mirror bodies, it provides good operating field and space for clinicians in various parts of the human body, which is convenient for clinicians to conduct minimally invasive diagnosis and minimally invasive treatment. Endoscopy technology brings operational space for minimally invasive treatment. Minimally invasive treatment will already become one of the important branches of future medical development.

Compared with traditional open surgery, minimally invasive surgery has the characteristics of less trauma, less bleeding and faster postoperative recovery. With the improvement of scientific and technological level, minimally invasive treatment techniques and related instruments have become more mature and reliable, and some minimally invasive surgery has become the first-line treatment plan in clinical medicine.

Usually a traditional endoscope host is about millions of yuan, soft mirror tens of thousands of yuan, plus maintenance costs, disinfection costs, human expenditure, the cost is not cheap, grass-roots institutions basically "can not afford to buy" also "can not afford to use".

The serious lack of endoscopic resources at the grassroots level is the vision of disposable endoscope entering the grassroots level to solve the lack of medical resources of the public. As an emerging force, disposable plastic endoscope can realize immediate examination, obtain information about patients' diseases and complications, and improve the level of primary medical services and the ability of patient management. Due to its convenience and low cost advantages, it is suitable for various primary medical institutions and doctors, which is helpful to achieve rapid diagnosis and treatment, screening and referral and diversion.

Distributed acoustic sensing (DAS) technology realizes the real-time monitoring of the optical cable or pipeline by using the backward Rayleigh scattering signal in the optical fiber. The technology is based on a phase-sensitive optical time domain reflector (Φ -OTDR) to reconstruct and detect events such as sound or vibration by detecting the backscattering signal generated when coherent pulse light propagating through the optical fiber.

 In the optical cable monitoring, the DAS system can accurately restore the sound information around the optical cable, such as vehicles, man-made damage, etc., and filter through the intelligent analysis function, interference signals, to ensure the accurate identification of events.

For pipeline monitoring, DAS technology can simultaneously measure various parameters, such as acoustics, temperature, pressure, strain and hole noise, and quickly and accurately detect and classify leakage events, third-party interference and other threats, providing a strong guarantee for the safe operation of the pipeline.

Bill Gates predicts that within five years, AI agents will become increasingly popular, and users will have their own dedicated AI agents.

An AI agent is a system based on large-scale language models that has the ability to perceive, understand, and execute tasks autonomously. The ability of autonomous perception heavily relies on the development and application of computer vision. As every user is expected to have their own specialized AI agent in the future, this expanding market will create new opportunities for downstream industries, including the demand for optical fiber components in machine vision.
