Abstract

A multicore fiber (MCF) with the standard cladding diameter is expected to be deployed in the early stage of a spatial division multiplexing-based transmission system. Inter-core crosstalk in an MCF is closely related to the bending conditions, so it is expected to vary with the deployment conditions. The bending radius dependence of the crosstalk can be modeled in accordance with the power coupling theory. In this paper, we experimentally investigate the crosstalk property variation among spooled, cabled, and installed MCFs and show that the crosstalk increases slightly in the cabled and installed conditions compared to in the spooled fiber. We numerically examine this crosstalk change by considering the power coupling theory and actual bending conditions in a high-density optical cable. Our findings reveal that the crosstalk change during the cabling and installation processes corresponds to a change in the bending state, and that the crosstalk after installation has a good correlation with the effective bending radius in the cable.
