Results: output amplified signal power of dual forward pumping with wavelength 980 nm for different pumping power and different EDFA length.
Output amplified signal power in dual forward pumping with wavelength 980 nm (W/nm)|
with the constant input signal power = 0.001 mw
|EDFA length 10 m||EDFA length 50 m||EDFA length 120 m|
|Pump power = 0.22 w||0.009||0.005||0.0025||S/g power decreases|
|Pump power = 0.62 w||0.0023||0.0145||0.01||S/g power decreases|
|Pump power = 1 w||0.03||0.024||0.0165||S/g power decreases|
|Remarks||S/g power increases||S/g power increases||S/g power increases|| |
