“…The key detrimental effects that limit the achievable transmission distance in most optical systems are amplitude and timing jitter. Our results show that in our test system, the timing jitter is larger at 40 Gb/s than at 10 Gb/s due to nonlinear optical pulse-to-pulse interactions [5]. This result is significant, since error-free detection is limited to about 5.5 ps of timing jitter in a 10-Gb/s system and to about 1.5 ps at 40 Gb/s [6].…”

“…8, we show the timing jitter measured by the scope using crosses and the results of the RF tone measurement using diamonds. Since the bandwidth of our electrical equipment is limited to about 40 Gb/s, we can only apply the RF tone method to 10 Gb/s transmission [5]. The solid line represents the simulation result of the absolute timing jitter from the scope method , while the dashed line shows the simulation result of (central time method).…”

We present a comparison between experiment and simulation of a 40-Gb/s periodically stationary dispersion-managed soliton (DMS) system in a recirculating loop. We find that we can propagate an error-free signal over 6400 km at 40 Gb/s and over 12 000 km if we lower the data rate to 10 Gb/s, keeping all other parameters constant. A careful analysis of the limiting factors shows the strong influence of nonlinear optical pulse-to-pulse interactions, causing a large increase in timing jitter. At a transmission distance of 6400 km, a large fraction of the jitter is due to pulse-to-pulse interactions. Moreover, we find that the system performance is very sensitive to parameter variations. We conclude that periodically stationary DMS systems suffer from numerous problems when increasing the data rate, suggesting that it may be impractical for wavelength-division multiplex transmission at 40 Gb/s.

“…This allows the RF spectra/AC waveforms of 640 Gb/s signals to be captured accurately. Thirdly, the timing jitter results obtained using the PC-RFSA method represent the true timing jitter in the system, while the jitter measured using an optical sampling oscilloscope (OSO) is affected by the influence of amplitude fluctuations [25]. The limited temporal resolution of the OSO (> 600 fs) not only restricts the operating bitrates but also produces jitter measurement errors for data rates of  640 Gb/s.…”

We report the first demonstration of simultaneous multi-impairment monitoring at ultrahigh bitrates using a THz bandwidth photonic-chip-based radio-frequency (RF) spectrum analyzer. Our approach employs a 7 cm long, highly nonlinear (gamma approximately 9900 /W/km), dispersion engineered chalcogenide planar waveguide to capture the RF spectrum of an ultrafast 640 Gb/s signal, based on cross-phase modulation, from which we numerically retrieve the autocorrelation waveform. The relationship between the retrieved autocorrelation trace and signal impairments is exploited to simultaneously monitor dispersion, in-band optical signal to noise ratio (OSNR) and timing jitter from a single measurement. This novel approach also offers very high OSNR measurement dynamic range (> 30 dB) and is scalable to terabit data rates.

The timing jitter in higher order dispersion managed soliton over 4,000 km link length has been investigated. The performance of the system under varied conditions of pulse shape, chirp factor, data rate amplifier spacing has been explored. The higher order soliton of gaussian shape in comparison to super-gaussian have shown reduction in timing jitter. Its results have been fitted in trend lines to form an empirical relationship with distance. The plots at varied chirp factor of gaussian and super gaussian shaped soliton for the system have been provided which show identical behaviour. However, fluctuations in timing jitter can be reduced by a proper chirp factor for the both. The timing jitter for gaussian shape soliton at data rates 20 and 10 Gbps has been plotted which indicates its early growth in the former data rate case. Further, varied amplifier spacing for the same 4,000 km link length in the system indicated that reasonably smaller amplifier spacing can reduce dispersion management induced timing jitter.
