This is another example of a double-clad fiber amplifier. Different from the above example, we consider all cladding modes and use the built-in mode solution method. According to the refractive index distribution, the numerical aperture of the core, and the conditions of the cladding pumping mode, the mode characteristics are calculated. For simplicity, set the […]
1 Introduction G. 657 optical fiber is also called bending loss-insensitive optical fiber. The fiber optic cable that is thinner than ordinary telephone line used for FTTH entry is G. 657 fiber. Without G. With 657 fiber, there is no large-scale application of FTTH. G. 657 optical fiber is divided into multiple sub-categories, currently commonly […]
Fiber patch cords can be divided into simplex and duplex according to the working mode of the interface. What is simplex and duplex? Both simplex and duplex are two modes of communication channels in telecommunications and computer networks. Simplex and duplex jumpers can also be called single and double (single core, dual core). What is […]
Optical module is composed of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic device includes two parts: transmitting and receiving. The transmitting end converts the electrical signal into an optical signal, and after transmitting it through the optical fiber, the receiving end converts the optical signal into an electrical signal. structure The transmitting part […]
Briefly, the program calculates the distribution of fiber modes by solving the overall model. The script program needs to define the refractive index distribution value. Through several lines of program code, read the refractive index value in turn, and interpolate to draw the refractive index function n_f(r) graph. The following is the related graphics of […]
