Design And PerformanceAnalysis Of Transmission Module Of The Fiber Energy Transmission System

Electrical energy transmission has been developed for a long time, the technology is relativelymature, but there are many defects. With the advance of science and technology, the requirements ofenvironment for energy transmission become higher and higher, traditional energy transmission hasbeen unable to meet the demand of high efficiency and security. With the development oftechnology,the optical fiber transmission system will replace the energy transmission as a newmode of transmission，and the optical fiber will play an important role.Firstly, the optical fiber transmission system was introduced, the system transfer the energy bylight with4modules. This paper focuses on the transmission module. By the combination ofphotonic crystal fiber and traditional fibers, the triangular lattice photonic band gap fiber isproposed. On this basis, in order to reduce the material absorption, silicon dioxide (SiO2) is used asthe substrate material of optical fiber. Secondly, RSoft software combined with Plane Wave Method(PWM) is used for the simulation study. With different duty ratios of the cladding simulated, it isconcluded that when air filling factor is0.85, the lattice constant is1.6um, the fiber can transmit850nm wavelength. Then, by using the finite element method (FEM) combined with COMSOLsoftware, the same photonic crystal fiber package layers with different core sizes and the same coresize with different photonic crystal fiber package layers were simulated. The simulation resultsshow that if the fiber transmits energy with surface modes, the leakage loss will increase, thepresence of surface modes is only related to the core size, and it has nothing to do with the claddinglayers. On this basis, the final design of the core radius is26um, photonic crystal fiber claddinglayer is15layers, the loss is0.0105dB/km. Finally, the device of every module is selected and listedthe application of system.
