For this purpose, 16 channels Wavelength Division Multiplexed (WDM) system with channel spacing of 5.3 nm is taken into account. -30 dBm powers at the input signals (1530 nm-1610 nm) are applied to three port filter and then input signals are separated into C and L bands. Each band signals are separately amplified in double pass configuration. Finally, all signals are combined into a coupler and the overall configuration has wide bandwidth, high gain and low noise. © 2013 The Chamber of Turkish Electrical Engineers-Bursa.falseConference Paper10.1109/eleco.2013.671391610.1109/eleco.2013.67139162-s2.0-84894185188
