1. What are the components of an optical fiber? Answer: An optical fiber consists of two basic parts: a core made of transparent optical material and a cladding and coating layer.

2. What are the basic parameters of the transmission characteristics of an optical fiber line?
Answer: They include loss, dispersion, bandwidth, cutoff wavelength, and mode field diameter, etc.

3. What are the causes of fiber attenuation?
Answer: Fiber attenuation refers to the reduction of optical power between two cross-sections of a fiber. It is wavelength-dependent. The main causes of attenuation are scattering, absorption, and optical loss caused by connectors and joints.

4. How is the fiber attenuation coefficient defined?
Answer: It is defined as the attenuation (dB/km) of a uniform fiber over a unit length in a steady state.

5. What is insertion loss?
Answer: It refers to the attenuation caused by inserting optical components (such as connectors or couplers) in the optical transmission line.

6. What is the bandwidth of an optical fiber related to?
Answer: The bandwidth of an optical fiber refers to the modulation frequency at which the amplitude of the optical power is reduced by 50% or 3 dB compared to the amplitude at zero frequency in the transmission function of the fiber. The bandwidth of the fiber is approximately inversely proportional to its length, and the product of the bandwidth length is a constant.

7. What types of fiber dispersion are there? What is it related to?
Answer: Fiber dispersion refers to the broadening of the group delay within a fiber, including mode dispersion, material dispersion, and structural dispersion. It depends on the characteristics of the light source and the fiber.

8. How is the dispersion characteristic of signal propagation in an optical fiber described?
Answer: It can be described by three physical quantities: pulse broadening, the bandwidth of the fiber, and the dispersion coefficient.

9. What is the cutoff wavelength?
Answer: It is the shortest wavelength that can be transmitted in the fiber. For single-mode fibers, the cutoff wavelength must be shorter than the wavelength of the transmitted light.

10. What impact does fiber dispersion have on the performance of an optical fiber communication system?
Answer: Fiber dispersion causes the optical pulse to broaden during transmission in the fiber. It affects the bit error rate, the length of the transmission distance, and the system rate. The phenomenon of optical pulse broadening caused by the different group velocities of different wavelengths in the light spectrum components of the light source.
