Comparison of EDFA and Raman Amplifiers Effects on RZ and NRZ Encoding Techniques in DWDM Optical Network with Bit Rate of 80 Gb/s

چکیده
The demand for optical networks with a high bit rate at a long transmission distance is growing at yearly basis [1,2]. The signal transmission in optical networks experiences propagation attenuations along a long span of optical fiber links, which in units of dB/km is defined by (10 / ) log( / ) α = − o in L P P , where in P is the input power to the fiber and o P denotes the output power at the fiber end [3]. To compensate this loss of signal power, Erbiumdoped fiber amplifier (EDFA) and Raman amplifiers are usually used along the transmission link [3].
