Abstract :
We demonstrate multicore EDFA with simultaneous 7-core pump by utilizing small-diameter fibre bundle fan-in/out. We confirm the characteristics with the gain > 15 dB, the noise figure <; 7 dB, and the crosstalk <; -40 dB in C-band. Seven 10 Gbit/s NRZ data are simultaneously amplified in each core with the power penalty within 0.5 dB.
