This chapter introduced analysis of gain and noise figure of
Erbium Doped Fiber Amplifier (EDFA) based on double pass with Wave Selective
Coupler (WSC). The use of fiber optic components in communication systems is
increasing as it has several features including wide bandwidth, high capacity,
and fast transmission. Multiple laser source (MLS) was used to generate the
signal light into the fiber. Optical Circulator (OC1) was used to redirect the
reflected optical signal from (OC2) to the output. Pump laser was used to the
ions excitation in erbium doped fiber for power amplification. Double pass EDFA
with wave selective coupler (WSC) in L band was the initial set up. The benefit
of choosing this method is to reduce the self-saturation effect of ASE. Also show
the effect on input and output signal power in L-band Erbium Doped Fiber
Amplifiers with pump power using forward pumping. Also analyzed were the
high-yield behavior and characterization details of the new double-pass EDFA
with WSC. We also show the effects of pump power on gain and noise figure with
input and output signal power in L- band at 1590 nm. Main contribution in this
study is to eliminate the residual pump power out of the signal and attain
optimal result in L- band were used.
