High Capacity Ultralong-Haul Power Efficient Transmission Using 12-Core Fiber

We use multicore fiber to demonstrate power efficient, high capacity ultralong-haul spatial division multiplexing (SDM) transmission. Feasibility of 105.1 Tb/s transmission over 14,350 km in a 12-core fiber is shown using a power efficient modulation format and an optimized optical system design. Pump power equivalent to a single 800 mW laser is used to provide amplification for all 12 SDM paths.
