摘要： Apparatus for implementing the application of duo-binary signal encoding in high-power, high-speed transmission systems which may be employed to mitigate the problem of stimulated Brillouin scattering. A dual-drive Mach-Zehnder interferometer modulator is used, with data being applied to both modulation inputs. The voltage difference between the two modulation inputs is between −V&pgr; and +V&pgr;. In one embodiment, the data signal is applied to one input, and the same signal, delayed by one bit, is applied to the second input, and the modulator is biased so as to have minimum throughput when both inputs are identical. In the second embodiment, the data signal is applied to one input and the complementary data-bar signal, delayed one bit, is applied to the second input, with the modulator biased to minimum throughput when both inputs are identical. This novel implementation has been verified experimentally showing a power penalty of less than 1 dB relative to a conventional binary signal. No inherent penalty is expected. Likewise it is demonstrated that significant increases of the SBS will increase the bit rate of duo-binary encoded signals. For example, the SBS threshold at 10 Gb/s is 12.7 dB higher for duo-binary encoding than for conventional binary modulation.

A dual-drive Mach-Zehnder interferometer modulator is used, with data being applied to both modulation inputs.

摘要： Techniques to adjust sampling times of an input signal. The techniques may utilize multi-level modification of the phase of a sampling clock. For example, the level of modification of the phase of the sampling clock may depend on the phase angle of the sampling clock in which transitions of the input signal occur.
