摘要: This essay designed a kind of new seven-core fiber with lower crosstalk and loss, made space division multiplexing transmission experiment based on this fiber. It is known that has the most serious influence in multicore process. Before experiment, affecting factors were analyzed through simulation, such as core space, bending radius, length. Combined simulation analysis, design scheme low was obtained. design, various core-to-core distance, length so on. Based conclusion multi-core optimal crosstalk. The wavelength technology, adopted to conduct optical 58.7km. adjacent suppressed 45dB/km, attenuation inner 0.24dB/km, outer cores' 0.32dB/km. Different bit error rate (BER) performances also studied under different conditions, reasonably designing system reduce rate, improve performance system, realize long distance large capacity
