Due to the all-time growing demand for higher network capacity, during recent years a lot effort was made not only to build new high performance optical transmission systems, but also to improve the operation of already existing systems. Optical amplifiers are such type of network elements the operation of which can severely impact the performance of a whole system. Many factors can impact the performance...
The purpose of this paper is to evaluate system performance dependence on channel spacing and data rate per channel if a single discrete Raman pre-amplifier is used for loss compensation. For comparison to make sense both systems are designed to have the same data rate, i.e. 320 Gbps, modulation, i.e. binary differential phase shift keying and equal spectral efficiency with 1.6 THz total occupied...
The aim of this paper is to estimate the impact of changing channel spacing in a wavelength division multiplexed (WDM) transmission system on the performance of the in-line erbium doped fiber amplifier (EDFA). The performance of the EDFA was investigated in a 16 channel 9.953 Gbit/s WDM transmission system with non-return-to-zero encoding technique, intensity on-off keying modulation format (NRZ-OOK)...
The aim of this paper is to demonstrate the ability of a fiber optical parametric amplifier to increase the number of carriers two times in a 32 channel wavelength-division-multiplexed active optical network. The parametric amplifier is placed at the receiver section. The 32 carriers are obtained by using 16 initial carriers, which while processing through the high non-linearity fiber, initiated the...
The main goal of this paper is to investigate the ability of a single-pump fiber optical parametric amplifier with linearly polarized pumping radiation to provide binary polarization shift keying to intensity on-off keying modulation format conversion in a single channel optical transmission system. The amplifier produced up to 14.8 dB of on-off gain, and it was demonstrated that such level of amplification...
