Comparative Analysis of Power Penalty versus Crosstalk in Optical Active Network Components like Erbium Doped Fiber Amplifier, Raman Amplifier and Semiconductor Optical Amplifier

Abstract

Optical amplifiers boost the power of optical system without optoelectronics (O-E-O) conversion. The optical amplification process is accompanied by Amplified Spontaneous Emission (ASE) noise that accumulates along the transmission line and degrades the optical signal to noise ratio (OSNR). Intensity modulation in one channel causes crosstalk in the other channel via the change of the complex refractive index in the amplifier. In this paper, authors tried to calculate and compare the power penalty of different optical amplifiers with help of knowledge of Bit Error Rate. In this work, authors have computed the Power Penalty at reference Bit Error Rate scale of  . For our mathematical analysis of experimental results considered the Gain (G) equals to 40, 25 and 15 dB for Erbium Doped Fiber Amplifier (EDFA), Raman Amplifier (RA) and Semiconductor Optical Amplifier (SOA), respectively at 1550 nm wavelength.
