what could be the attenuation for optical fiber used in fiber Bragg grating sensor with a operating wavelength of around 1550nm

Optical fiber attenuation refers to the loss of light intensity as it travels through the fiber. This loss can be due to various factors such as absorption, scattering, and bending of the fiber.
Optical fiber attenuation is measured in decibels per kilometer (dB/km). This measurement is obtained by comparing the input power to the output power of the fiber and taking the logarithm of the ratio.
1550nm FBG sensors operate at a specific wavelength of 1550nm and rely on the amount of light transmitted through the fiber to accurately measure changes in the environment. Any attenuation in the fiber can affect the accuracy and sensitivity of the sensor.
There are several factors that can affect optical fiber attenuation, including the quality of the fiber, the wavelength of light, bending or stress on the fiber, and environmental conditions such as temperature and humidity.
To minimize optical fiber attenuation for 1550nm FBG sensors, high-quality fiber with low attenuation should be used. Proper installation and handling of the fiber, such as avoiding sharp bends, can also help reduce attenuation. Additionally, using appropriate protective coatings and environmental controls can help maintain stable attenuation levels.
