As one of the cores of medium and long-distance optical communication, the optical module plays a role in photoelectric conversion. It is composed of optical devices, functional circuit boards, and optical interfaces.

The fiber optic sensor network has three basic components, one of which is called a single-point sensor. An optical fiber only plays the role of transmission here, and the other is called a multi-point sensor, where one optical fiber connects many sensors together so that many sensors can share the light source to realize network monitoring. Then there is the smart fiber optic sensor. The multi-point optical fiber sensor is a grating from the outside, and periodic intervals are found through ultraviolet irradiation. When an optical fiber is incident, if the wavelength of the optical fiber is exactly twice the interval, the light wave will be strongly reflected, and if the optical fiber is subjected to temperature changes or strains, the reflected wavelength will change. This kind of sensor There can be many on one fiber, and it can be used for a variety of sensing applications by connecting them.

Fiber amplifier in a fiber optic data link, the amplification process that occurs over a very long transmission fiber.

The semiconductor laser amplifier is small in size, wide in frequency band, and high in gain, but the biggest weakness is that the coupling loss with the optical fiber is too large, and it is easily affected by the ambient temperature, so its stability is poor. Semiconductor optical amplifiers are easy to integrate and are suitable for use in combination with optical integration and optoelectronic integrated circuits.

The SLED light source is an ultra-wideband light source designed for special applications such as sensing, fiber optic gyroscopes, and laboratories.
