An introduction to optical waveguides

Back scattering method is the most universal method applied to control fiber optic transmission line characteristics. This method is recommended by ICU-T and national standards of Russia. It is widely used during determination of regularity and attenuation of optical fibers, irregularity localization and its loss, evaluation of length of installed fiber optic lines, measurements of attenuation both individual sections and whole optical line, control of delivery length etc. Thus an error estimation of considered method during measurements of splice loss is necessary. Theoretical and experimental analysis of back scattering method error during splice loss measurements is represented.

In article results of experimental researches of resistance to optical cable bends on an output from closure port are submitted. The test data optical cable with increased inflexibility in extreme conditions are resulted. Recommendations on increase of resistance to small radiuses bends for of optical cables on an output from closure at the lowered temperature are considered.

This work presents some results of pulse and spectral responses, performed for laser-excited pilot sample of earlier on designed and fabricated chiral silica few-mode optical fiber (FMF) with induced twisting 66 revolutions per meter (rpm), typical (for telecommunication optical fibers) cladding diameter 125 μm, weakly increased core diameter up to 11 μm and numerical aperture NA=0.22, corresponding to improved height of quasi-step refractive index profile. Described FMF 11/125 provides propagation of 4 and 6 guided modes over “C” and “O”-bands, respectively. We present results of tests, focused on researches of few-mode effects, occurring under laser-excited optical signal propagation over pilot sample optical fiber, and their influence on pulse and spectral responses, including some measurements, performed for fiber Bragg grating, recorded in tested FMF 11/125.

In this paper, the signal propagation is described by a generalized nonlinear Schrodinger equation take into account linear and nonlinear mode coupling. A modified solution based on split-step Fourier method is considered. The method for simulation of mode coupling coefficients based on statistical characteristics is proposed. Results of bit error rate estimations for space division multiplexing signal propagation in few mode fiber communication line for weak and strong coupling regime are represented.
