We report a reduced complexity single polarization all-pass modulation scheme that uses overlap and discard to implement continuous transmission. We find that transmitter NSRs of −25 dB and −21 dB can be achieved with 1/3 and 1/6 the complexity, respectively, of reported solutions. We compare this modulation scheme with a conventional Mach-Zehnder modulator solution by measures of throughput, spec...Show More
We consider methods for containment of the effects of optical nonlinearities in coherent optical transmission. These are distinguished according to their practicality and effectiveness.Show More
For excellent cost and performance, modern high capacity transport systems use digital coherent processing to overcome many physical barriers. Coherent methods are explained and measured performances are shown for commercial coherent systems at 100 Gb/s and beyond.Show More
In summary, we have demonstrated the importance of including modulator chirp and filtering in assessing the implications of group delay ripple (GDR) in dispersion compensating fiber Bragg gratings. Otherwise misleading results can be obtained.Show More
The change in the chromatic dispersion of optical fiber with temperature is an important design parameter for 40-Gb/s systems. We derive an equation for the change in dispersion with a temperature that is more general than what has previously been published. We present experimental results for the change in fiber dispersion with temperature for six commercially available fiber types of interest fo...Show More
It has been shown that to accurately assess the implications of the group delay ripple (GDR) of a dispersion compensating fiber Bragg grating on system performance it is necessary to consider the chirp of the modulated optical signal. The variation in the receiver sensitivity for the five modulators considered in this paper is less significant for a peak-to-peak GDR less than 10 ps, although curre...Show More
