Transmission Speed

In recent years, the information technology sector has developed rapidly and there has been a rapid increase in the amount of information transmitted. The demand for larger telecommunication network capacities is growing, therefore it is necessary to increase the number of channels and transmission speed in wavelength division multiplexed transmission systems. Various optical amplifiers can be used to compensate for the attenuation of the accumulated signal (over a wide wavelength range). The Doctoral Thesis did research on the use of EDFA, Raman, FOPA and combined optical amplifiers in wavelength division multiplexing systems. In the work, special emphasis is placed on erbium and ytterbium alloy fibers with the study of computer modeling of optical amplifiers in cladding pumping technology.

Fiber Optical Parametric Amplifier

A photonic crystal fiber (PCF) with a zero-dispersion wavelength (ZDW) in the telecommunication region is designed and an ultra-broadband fiber optical parametric amplifier (FOPA) based on such PCF is simulated. Results show that the PCF-based FOPA exhibits much higher gain with a very broad bandwidth (covering O- to U-band) in comparison with the highly nonlinear fiber (HNLF)-based FOPA. Also, the required fiber length and the input pump power are reduced for the PCF-based FOPA. The obtained results show the great potential of the PCF-based OPA for the telecommunication applications, e.g. amplification of wavelength-division multiplexing (WDM) signals.

AbstractIn this paper we have study the performance of different optical amplifiers (Erbium doped amplifier (EDFA), RAMAN amplifier, and semiconductor optical amplifier (SOA)) for 80 channels wavelength division multiplexing (WDM) system with the data rate at 10 Gbps data rate for the transmission distance of 280 km After getting the results of these amplifiers the performance of these has to be compared The Q-factor values achieved better in EDFA as compared to SOA and RAMAN. While the BER getting good in SOA as compared with other amplifiers but in EDFA after 200 km it goes saturated, the Power achieved at the power estimator is getting better in EDFA optical amplifier while in other amplifier it achieved negative. At the end it is also study the Power with frequency in THz and the Eye Diagram of such amplifiers results.

Currently it is not possible to create a fully optical communication system without a software tool which simulates an optical communication line in real conditions prior to its construction. The aim of this article is to establish a comparison between the EDFA (erbium doped fibre amplifier) and SOA (semiconductor optical amplifier) optical amplifiers in the WDM (wavelength division multiplexing) system. The system contains a four-channel WDM with speed of 10 Gbps and optical fibre with length of 80 km. Simulations are conducted in the programme environment “OptSim.” The quality of the optical communication system is evaluated by the BER (bit error rate) and Q-factor for individual wavelengths, namely, of 1558 nm and 1562 nm, which are within the C-band.

Hybrid Optical Amplifier

We have proposed a very advanced super dense wavelength division multiplexing (SD-WDM) system using RAMANErbium doped silica fiber optical amplifier (EDSFA) hybrid optical amplifier (HOA) in this paper. Performance is evaluated in term of flattened gain and noise figure for C-band. Effect of proposed hybrid optical amplifier also compared with EDFARAMAN, EDFA-SOA and SOA-SOA HOA for the same characteristics. Best rating gain of 37.5 dB with noise figure of 5.4 dB ever recorded from RAMAN-EDSFA HOA. It is also observed that out come from SOA-SOA HOA is not acceptable in term of noise figure of 9.1 dB for 400 x 10 GB/s SD-WDM system. Keywords: SD-WDM, RAMAN-EDSFA, EDFA-RAMAN, EDFA-SOA, SOA-SOA, noise figure, gain
