The correct answer is: A. A loss mechanism related to the material composition and fabrication of fiber
Material absorption is a loss mechanism that occurs when light interacts with the material of an optical fiber. The light is absorbed by the material and converted into heat. This loss mechanism is related to the material composition and fabrication of the fiber.
The following are brief explanations of each option:
- B. A transmission loss for optical fibers
Transmission loss is a general term that refers to any loss of light that occurs as it travels through an optical fiber. Material absorption is one of the many factors that can contribute to transmission loss.
- C. Results in attenuation of transmitted light
Attenuation is a decrease in the power of a light beam as it travels through an optical fiber. Material absorption is one of the many factors that can contribute to attenuation.
- D. Causes of transfer of optical power
Transfer of optical power is the process of transporting light from one point to another using an optical fiber. Material absorption is not a factor that contributes to the transfer of optical power.
