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 with 51 dB (54 dB) gain and 3.1 dB NF for only 45 mW (93 mW) of pump power.
