Fiber optic module can be divided into fiber optical receiver module, fiber optical transmission module, fiber optical transceiver module and fiber optical transponder module.

Accurate and real-time detection of methane gas becomes critical for natural gas pipelines leakage monitoring, household safety and coal mining safety production monitoring.

Optical fiber temperature measurement technology is a new technology that has only been developed in recent years, and has gradually revealed some excellent characteristics. But just like other new technologies, optical fiber temperature measurement technology is not a panacea. It is not used to replace traditional methods, but to supplement and improve traditional temperature measurement methods. By giving full play to its strengths, new temperature measurement solutions and technical applications can be created.

An optical fiber sensor is a sensor that converts the state of the measured object into a measurable light signal. The working principle of the optical fiber sensor is to send the incident light beam from the light source into the modulator through the optical fiber. The interaction between the modulator and the external measured parameters determines the optical properties of the light, such as the intensity, wavelength, frequency, phase, polarization state, etc. It changes and becomes a modulated optical signal, which is then sent to the optoelectronic device through the optical fiber and passed through the demodulator to obtain the measured parameters. During the whole process, the light beam is introduced through the optical fiber, passes through the modulator, and then emitted. The role of the optical fiber is first to transmit the light beam, and secondly to act as an optical modulator.
