Newly developed OTDR measurement technique validated that the in-span XT BS in MCFs can be well predicted by Eq. (3); therefore, bidirectional MCF transmissions with propagation direction interleaving between neighboring cores are very effective for XT suppression as presented in –[1 3,7,8]. The suppression of FIFO XT is also important for designing XT BS in bidirectional MCF transmission systems, and the effect of FO XFI T can be well estimated using Eq. (17).

N2 - We experimentally demonstrate the in-span nonlinear accumulation of Rayleigh backscattered crosstalk in multicore fibers by novel distributed evaluation technique using multi-channel OTDR, which validates the previously-reported theoretical prediction. We also present the impact of fan-in/fan-out crosstalk on the backscattered crosstalk with experimentally-validated prediction formula.
