We analyze fiber transmission penalties due to erbium-doped fiber amplifier (EDFA) power transients that result from fiber nonlinearity and ASE noise in a chain of 10-20 EDFAs with as many as 32 wavelength-division multiplexing (WDM) channels. We find due to worst case power transients: (i) system performance is severely degraded (up to few 10s of dB) both(More)
—A symmetrized split-step Fourier (SSSF) simulation model with global simulation accuracy control is extended to vector optical fiber multi-span propagation cases, which are applicable to the waveform level simulation of polarization multiplexed coherent optical communication systems. Using local error bound obtained from a scalar simulation package, the(More)
After an introduction to the nonlinear fiber transmission and an optimal channel equalization scheme, recently proposed analytical step-size selection and scaling rules was verified to achieve comparable global simulation accuracy for split-step Fourier (SSF) simulations of optical pulse propagation through fiber with low simulation accuracy. Its(More)
Simulation step-size optimization based on an analytical step-size selection rule is applied to the waveform level simulation of polarization multiplexed optical signal propagation through dispersion compensated optical fiber links over a large range of simulation accuracy level, chromatic dispersion, and differential group delay. Extensive numerical(More)
features of traffic on highways (2–5). To date, many DSRC message communication protocols have been proposed and tested for their reliability, congestion control, and other characteristics (5–7). Some of the current DSRC technology applications being developed include traffic data acquisition and dissemination systems, intersection collision warning(More)
By comparing with the exact optical communication system performance obtained using a quasi-analytical BER calculation method, we systematically analyze the accuracy of the Gaussian approximation (GA) method and the threshold-based margin measurement method for performance evaluation of on-off keying (OOK) optical amplifier systems. We reveal the inherent(More)
We propose a technique to electronically postcompensate fiber nonlinearity in ≥40 Gbit/s long-haul WDM transmission systems. We have analyzed this technique for return-to-zero and carrier-suppressed return-to-zero modulation formats using two different dispersion maps. Our analysis shows that the proposed technique can increase the overall system(More)
We demonstrate elimination of RF power degradation over 94 km of single-mode fiber in subcarrier transmission from 0.25 to 14 GHz by modulating a 35-ps soliton train. Our results show that solitons are good candidates for subcarrier transmission to avoid degrading dispersion effects.
A local error method based on an analytical scheme previously developed for the scalar optical fiber channel is applied to the second-order symmetrized split-step Fourier simulation of polarization multiplexed signal propagation through dispersion compensated optical fiber links. It is found that the global simulation accuracy for the vector propagation can(More)
