Исследование апертурных характеристик оптических волокон малой длины

In work the experimental research of aperture characteristics of short segments of singleand multimode telecommunication optical fibers on wavelengths of 655-690 nanometers is made. Base mode propagation in a fiber Corning SMF-28e and possibility of mode multiplexing in short communication line is showed. Distribution of optical radiation on a cover of short optical fibers is established.
