چکیده
We examine the correlations between the parameters of ultranarrow off-centred filtering and pulse width on the performance of a wavelength paired Nx40Gbit/s DWDM transmission, consisting of carrier suppressed return-to-zero signal with 0.64 bit/s/Hz (without polarizationdivision multiplexing) spectral efficiency.

The optimization of multiplexing (MUX) and demultiplexing (DMUX) 3-dB filter bandwidths for the optical differential quadrature phase shift key (DQPSK) combined with the return-to-zero (RZ) and carrier-suppressed returnto-zero (CS-RZ) is performed. The study of different optical signals in the 40 Gb/s dense wavelength division multiplexing (DWDM) system, with high spectral efficiency, is shown ...
متن کاملA Full-Duplex, Dual-Polarization 10Gbps Radio over Fiber system with wavelength reuse for upstream signal
This study presents a full-duplex Radio-over-Fiber (RoF) system providing the users' wireless access with a bit rate of 10 Gbps over 40 GHz radio carrier. This system can be used in a centralized radio access network (C-RAN) architecture because we provide a fully analog front haul link between central station and base station. We can consider it as infrastructure between remote radio heads (RR...
متن کاملUltra-Long-Haul WDM Transmission with High Spectral Efficiency
We review our recent work on ultra-long-haul wavelength division multiplexed (WDM) transmission with high spectral efficiency (SE) employing tight pre-filtering and multi-symbol detection. We start the discussion with a theoretical evaluation of the SE limit of pre-filtered modulation in optical fiber communication systems. We show that pre-filtering induced symbol correlation generates a modul...

A comprehensive study of the various modulation techniques has been discussed which helps to increase data rate, to overcome dispersion effects and various non-linear effects in the fibre. Modulation formats such as OOK (On Off Keying), BPSK (Binary Phase Shift Keying), DPSK (Differential Phase Shift Keying), DP-QPSK (Dual Polarized Quadrature Phase Shift Keying) and duobinary are studied. The ...
متن کاملCorrelations between Spectral Parameters of Earthquakes and Damage Intensity in Different RC Frames
In recent decades many researchers have studied on the damage assessment of structures after a seismic event. To assess the damage of structures under an earthquake, it is so important to study the correlations between earthquake parameters and damages of the structures. A lot of seismic parameters have been defined by researchers to characterize an earthquake. Spectral parameters of an earthqu...
