Development trend of special optical fiber

At present, with the increasing investment in the informatization construction of 3G and the integration of three networks in China, as well as the introduction of policies to revitalize the central and western regions, develop rural areas, and expand domestic demand, China's demand for optical fiber and optical cable and optoelectronic devices has maintained a strong growth momentum. With the improvement and expansion of information infrastructure in the future, it is expected that the demand for optical fiber and optical fiber devices will continue to grow. Special optical fiber has the following development trends:

(1) Special optical fiber with high added value and high technology content;

(2) Optical fiber communication devices: adjustable dispersion compensator, dynamic PMD compensator, high-power amplifier, optical parametric amplifier OPA, slow light and all-optical buffer, wavelength converter, etc;

(3) Energy fiber components: all optical fiber laser, single frequency, narrow linewidth and other high-power active fiber components and passive fiber components;

(4) Medical optical fiber devices: minimally invasive surgical devices, endoscopic medical devices, etc;

(5) Optical fiber sensing devices: devices for various special environmental applications, such as pressure, temperature, displacement and other parameters sensing and detection devices, fiber optic gyroscope, etc.
