Abstract-Optical amplification in the C and L band region with wave division multiplexing can provide over 160 channels. The paper provides simulation studies of such a wideband erbium doped fiber amplifier which utilizes a tunable tap at the TLS source end. This isolates and provides two parallel channels for simultaneous amplification in both C and L band. Such a configuration has shown to provide a gain well over 20dB from 1525-1615nm bandwidth with an average noise figure of 10dB (approx.). Gain saturation effects beyond20dBm/channel signal level and, gain spectra at different pump powers and amplifier lengths have also been studied.
