Erbium-doped fibre amplifier with 54dB gain and 3.1dB noise figure
It is shown that for practical pump powers (33 dB) and low noise figure (3 dB) cannot simultaneously be achieved with a conventional codirectionally pumped EDFA. However, using a codirectionally, pumped composite EDFA incorporating an isolator overcomes the problem and we demonstrate an amplifier wi...
