100-Gb/s transmission over a 2520-km integrated MCF system using cladding-pumped amplifiers

A 10.5-Tb/s optical transmission (15 × 100 Gb/s QPSK channels per core) over 2520 km of multicore fiber is achieved using an integrated multicore transmission link consisting of directly spliced multicore components, such as fan-in/fan-out fiber couplers, a 60-km trench-assisted seven-core hexagonal fiber and cladding-pumped erbium-ytterbium-doped fiber amplifiers.
