AbstractHybrid Optical Amplifier (HOA) has made a significant change in Wavelength Division Multiplexed (WDM) optical networks. We have proposed diverse hybrid optical amplifier configurations for the better performance of WDM optical networks. These configurations are SOA-EDFA, EDFA-EDFA and EDFA-Raman amplifier for 24 channels WDM optical networks at 10 Gbps with channel spacing of 0.8 nm. The performance of the systems is evaluated on the behalf of different parameters such as, quality factor, eye diagram, bit error rate and output power. The efforts are made to optimize these parameters. From the results, it is assessed that EDFA-Raman configuration gives superior results as compared to EDFA-EDFA configuration and SOA-EDFA hybrid optical amplifier configuration for long distance. Further it is also observed that EDFA-Raman hybrid optical amplifier configuration is suitable for high data rates up to 20 Gbps.

Triple Play Services

In the near future, broadband access networks will be required with data rates of over 1Gbit/s per customer. Currently, time-division multiple access passive optical networks (TDMA-PONs) are deployed. However, TDMA-PONs cannot keep up with the requirements for the broadcasting of a great number of HDTV channels and the unicasting of several triple-play services (voice, data and video). In contrast, wavelength-division-multiplexed PONs (WDM PONs) will be able to provide these required high data rates per user causing higher costs than with TDM-PONs. The introduced paradigm shift, at least one wavelength per service and user, leads to the introduction of new aspects in the design of future WDM PON access networks. In techno-economic evaluations, new network architectures with the highest potential concerning economic considerations have been identified. Access to these newly identified network architectures will prompt market introduction as well as market penetration helping Fiber-tothe- Home (FTTH) to become reality.

AbstractLarge capacity optical networks require flattened gain spectrum and large gain bandwidth of the optical networks. In order to achieve this large number of hybrid optical amplifiers are designed. Here we proposed a competent flat gain hybrid optical amplifier with an optimum combination of Erbium Doped Fiber Amplifier (EDFA) and Raman amplifier. Attempts are made to design a hybrid optical amplifier for 100 channels, 10 Gbps Super Dense Wavelength Division Multiplexed (SDWDM) systems at different channel spacing of 0.1, 0.2, 0.4 and 0.8 nm. Work capacity of the network was compared on the basis of various parameters viz., gain and noise figure that determined the performance of the system. The gain spectrum of the hybrid optical amplifier depends upon the parameters viz., pump wavelength, pump power and laser input power of the amplifier. Various efforts were conceded out to optimize these parameters. It was found that for wavelength range 1,570.5–1,580.75 nm, a flat gain of 5.36 dB is achieved for input power of −15 dB with noise figure variation of 0.57 dB without using any gain flattering scheme. Being simple and cost effective, this hybrid optical amplifier could be recommended for gain flatness characteristics and acceptable noise figure for super dense wavelength division multiplexed system.

AbstractIn this paper, a competent flat gain hybrid optical amplifier is proposed with an optimum arrangement of erbium doped fiber amplifier (EDFA) and Raman amplifier. Attempts are made to design a hybrid optical amplifier for100 channels, 10 Gbps super dense wavelength division multiplexed (SDWDM) systems at channel spacing of 0.1 nm. Work capacity of the system was compared on the basis of various parameters, viz., noise figure and gain that determined the performance of the system. The gain spectrum of the hybrid optical amplifier depends upon the parameters viz., laser input power, pump power and pump wavelength of the amplifier. It was found that for wavelength range 1,560.38–1,579.59 nm, a flat gain of 4.34 dB is achieved for input power of −10 dB with noise figure variation of 0.818 dB without using any gain flattering scheme. Being simple and cost effective, this hybrid optical amplifier could be recommended for gain flatness characteristics and acceptable noise figure for dense wavelength multiplexed systems.

Abstract In this investigation comparison of various Passive optical networks (PON) standards has been done. Bidirectional fiber to home architecture is projected which simultaneously transmits the video and audio signals. The system uses travelling wave semiconductor optical amplifier with injection current of 0.45 A for both upstream and downstream channels. This architecture is investigated for a distance of 40 km and it accommodates 96 users. Further the effect of varied distance and power on Q-factor of system is investigated.
