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)
This report describes the architecture, functionality and the field demonstration results of a newly developed DSRC based V2I work zone traffic information system with V2V assistance. The developed system can automatically acquire important work zone travel information, e.g., the travel time (TT) and the starting location of congestion (SLoC), and relay(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)
The future deployment of dedicated short range communication (DSRC) technology requires that DSRC-based applications are integrated with existing traffic management techniques so that non-DSRC-equipped vehicles at the early stage of DSRC deployment can also reap the potential benefits of DSRC technology. We have successfully developed and field demonstrated(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.
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)
