Optical Fiber Communication widely implements Dense Wave Division Multiplexing (DWDM) technique in order to accommodate large number of channels within a limited bandwidth. But, this technology suffers a serious degradation in signal quality due to inter-channel interference. Optical Kerr Effect, in addition to this, worsens the situation. This paper deals with minimization of Four Wave Mixing (FWM)...
In present research, Aeff parameter measurements for ytterbium (Yb3+) and erbium (Er3+) doped optical fibers were performed experimentally by the usage of transverse shift measurement method. All the measurements were done at two different wavelengths (1310nm and 1550nm accordingly) at various power levels with an aim to evaluate how effective area depends on those parameters. With the increase of...
WDM transmission system capacity growth creates a need to increase EDFA output power. One of the most attractive solutions in this area is the usage of ytterbium doped fiber (EYDF), which ensures low non-linearity, without affecting the amplification efficiency. In this research master-oscillator power amplifier (MOPA) was modelled using different ytterbium co-doped fiber lengths: 10, 15, 20 and 25m...
In this research we investigated the performance of in-line Erbium Doped Fiber Amplifier (EDFA) in 40 Gbit/s 8 channels wavelength division multiplexing (WDM) transmission system with NRZ-OOK modulation format and 100 GHz channel spacing. Different EDFA configurations: co-propagation (980nm) and counter propagation (1480nm) were used in order to find an optimal settings with minimal noise factor indicators...
