Opis:: Accommodation of many channels in dense wavelength division multiplexing networks raises the average power density of the optical networks. This results in severe nonlinear effects in the optical networks. An optimized design of non-zero dispersion shifted fiber with an enormous effective area can overcome this nonlinear effect and also offer a minimum bending loss and splice loss for a dense wavelength division multiplexing system. In this paper, the alpha-peak profile is utilized for calculating electrical field distribution and designing the refractive index profile of the non-zero dispersion shifted fiber. This fiber has a high effective area of about 120 μm2. Conjointly, the accomplished fiber has a very low bending loss of 1.40×10–14 dB/km and reduced splice loss of 4.46×10–3 dB. Due to this high effective area, the dense wavelength division multiplexing network performance is upgraded by diminishing nonlinear effects. In addition, the newly designed fiber has also a very low dispersion slope (0.057 ps/nm2km). Thus, the proposed fiber is optimized to handle high bandwidth and multiple high bit-rate wavelength channels without nonlinear impairments in the 1.55 μm window long-haul dense wavelength division multiplexing systems.

Tytuł:: 1.28 Tbps DWDM optical network design using a dispersion compensating distributed Raman amplifier over S-band

Opis:: A 100 km long dense wavelength division multiplexed optical network design with a capacity of 1.28 Tbps is proposed in this paper. The novelty of this work is the use of a dispersion compensating fibre as a Raman amplifier in the S-band for a high-capacity dense wavelength division multiplexing network. The transmission is accomplished auspiciously in the wavelength range from 196 THz to 202. 35THz. The coupling of a Raman amplifier made the realisation of the S-band possible in the network, as the erbium-doped fibre amplifier is competent for amplification in C- and L-bands only. Further, a pump coupler is used for multiple pumping to enlarge the gain spectrum for a high-capacity optical network. The performance analysis of the network is carried out systematically in terms of bit error rate (BER), eye diagram, Q-factor, and optical signal to noise ratio (OSNR). The results demonstrate that the proposed set-up shows adequately low BER, sufficient Q-factor values, wide eye-opening, and commendable OSNR for all receiving channels.
