| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Multi-core fibers (MCFs), a type of space-division multiplexing (SDM) technology, have been investigated to overcome the theoretical transmission capacity limitation in standard single-mode fibers. Two types of weakly coupled MCFs have been proposed: a step-index (SI) profile MCF (SI-MCF) with a stepped refractive index profile and a trench-assisted MCF (TA-MCF) with a trench structure to suppress crosstalk (XT) between cores. Although SI-MCFs have a simple refractive index profile compared to TA-MCFs and can be expected to have superior manufacturability for mass production, the transmission distance is limited by the relatively large core-to-core XT. To suppress the degradation of the transmission performance due to core-to-core XT to achieve MCF long-haul transmission, bidirectional transmission technologies have been proposed. In this paper, we experimentally demonstrated transoceanic-class MCF transmission using standard cladding SI-type 4-core fibers with bidirectional transmission technology. 4-SDM/16-WDM channels modulated with 24-Gbaud dual-polarization QPSK are successfully transmitted over 7,000 km with no impact of core-to-core XT. | |
