Multi-Core Optical Fibers
Tetsuya Hayashi, Sumitomo Electric Industries, Yokohama, Japan
9.1 Introduction
Recent single-core transmission systems have achieved capacities up to about 100 Tb/s per fiber by employing time-, wavelength-, polarization-division multiplexing, and multilevel modulations [1–3]. However, the transmission capacity of the single-core fiber is rapidly approaching its fundamental limit, and the current trends of traffic growth—increasing by a factor of 10 in 5 years—and system capacity growth will result in capacity crunch in the near future [4,5]. In such a situation, spatial division multiplexing (SDM) is an attractive technology for further enlargement of the fiber capacity or spatial capacity—the capacity per ...
