Multicore fibers for high-capacity submarine transmission systems

Applications of multicore fibers (MCFs) in undersea transmission systems are investigated, and various potential architectures of branching units for MCF-based undersea transmission systems are presented. Some MCF-based submarine network architectures based on the amount of data traffic are also proposed. It is shown how different architectures of branching units affect the number of network components. The effects of intercore crosstalk on the network components are also investigated.
