Equalization-enhanced phase noise induced timing jitter.
نویسندگان
چکیده
In electronic digital signal processing based optical communication systems, digital equalization for chromatic dispersion interacts with local oscillator phase noise to produce equalization-enhanced phase noise (EEPN). In addition to both phase and intensity noises, EEPN also induces timing jitter to the equalized signal. For a 100 Gbit/s quadrature-phase-shift keying signal with laser linewidth of 300 kHz, the timing jitter is up to 20% of the symbol interval for a transmission distance of 1500 km.

Phase Statistics of Soliton
The characteristic function of soliton phase jitter is found analytically when the soliton is perturbed by amplifier noise. In additional to that from amplitude jitter, the nonlinear phase noise due to frequency and timing jitter is also analyzed. Because the nonlinear phase noise is not Gaussian distributed, the overall phase jitter is also non-Gaussian. For a fixed mean nonlinear phase shift,...
متن کاملAn adaptive phase equalizer for reducing timing jitter due to acoustic effect
The main source of errors for solitons when propagating in optical fibers is the timing jitter. Acoustic effect, unlike other sources of timing jitter such as the Gordon-Haus effect and the polarization effect that are stochastic in nature, is deterministic and is a source of inter-symbol interference ( S I ) . We introduce an adaptive phase equalizer to compensate for the acoustically induced ...

متن کاملPhase Noise and Jitter Characterization in Oscillator Applications
Recent advancements in communication systems design place strict demand on system timing accuracy. As frequencies approaches 1GHz, and beyond designers are required to pay special attention to timing variations. Jitter has become a familiar parameter to designers as system speeds accelerate. Jitter is usually characterized in the time domain via metrics such as deterministic jitter, random jitt...
متن کاملAnalysis of DLL Jitter Due to Substrate Noise
Substrate noise is the major source of performance limitation in mixed-signal integrated circuits. This paper studies substrate noise effects on the performance of delay-locked loops (DLLs). Due to their robust noise performance, the delay-lockedloops are widely used as clock generators of microprocessors. Although exploiting advanced circuit techniques reduces the timing jitter induced by the ...
