摘要：

The limitations of crosstalk and core-to-core distance in step-index multi-core fibers (SI-MCFs) are clarified for long-haul transmission, and the low-crosstalk MCF structures of trench-assisted MCFs (TA-MCFs) are investigated for realizing large effective area (Aeff) and high core density, simultaneously, with a limited cladding diameter. It is shown that the crosstalk between neighboring cores in TA-MCFs can be greatly suppressed even if the Aeff and the cutoff wavelength are fixed compared with SI-MCFs. In addition, the possibility of MCFs with heterogeneous core arrangement is considered for transmission fibers and low-crosstalk heterogeneous MCFs with bending radius insensitive characteristics are investigated.
