LC fiber cable is indeed divided into single-mode and dual-mode. The following

　Signal lines and fiber optic lines are two completely different transmission m

1.Briefly describe the composition of optical fiber? Answer: Optical fiber consists of two basic parts: the core and cladding, which are made of transparent optical material.   2. What are the basic parameters that describe the transmission characteristics of optical fiber lines? Answer: Including l

16. In current commercial optical fibers, which wavelength of light has the smallest dispersion? Which wavelength of light has the smallest loss? Answer: Light with a wavelength of 1310nm has the smallest dispersion, and light with a wavelength of 1550nm has the smallest loss. 17.How are optical fib

23.What does the armor of optical cable mean? A: It refers to the protective element (usually steel wire or steel belt) used in optical cables for special purposes (such as submarine optical cables, etc.). The armor is attached to the inner sheath of the optical cable. 24.What materials are used for

34. In fiber optic communication systems, the following items are commonly found. Please indicate their names. AFC, FC adapter ST adapter SC adapter FC/APC, FC/PC connector SC connector ST connector LC patch cord MU patch cord Single-mode or multi-mode patch cord 35.What is the insertion loss (or in

43.What is the nonlinearity of optical fiber? Answer: It means that when the input optical power exceeds a certain value, the refractive index of the optical fiber will be nonlinearly related to the optical power, and Raman scattering and Brillouin scattering will occur, causing the frequency of the

3. Absorption loss of materials The material used to make optical fibers can absorb light energy. After the particles in the optical fiber absorb light energy, they vibrate and generate heat, which dissipates the energy, thus generating absorption loss. We know that matter is composed of atoms and m

Fiber loss In recent years, fiber optic communication has been widely used in many fields. To achieve fiber optic communication, an important issue is to reduce the fiber loss as much as possible. The so-called loss refers to the attenuation of the fiber per unit length, and the unit is dB/km. The l
