Multi-core Fiber for High-Capacity Long-Haul Spatially-Multiplexed Transmission

摘要

Data traffic is growing exponentially due to the emergence of various network services. Although the transmission capacity of optical fibers has dramatically increased thanks to advanced communication technologies such as wavelength-division multiplexing and multi-level modulation, the capacity is rapidly approaching its fundamental limit as the amplification bandwidth has been used up and drastic improvements of the signal-to-noise ratio cannot be expected any further. To overcome this problem, space-division multiplexing has come to attract lots of attention, and we have conducted research and development on multi-core fiber (MCF), achieving positive results. This paper reviews the major achievements of our MCF research and development.
