摘要： An externally modulated laser-based transmitter is disclosed which utilizes an automatic bias control (ABC) circuit to maintain the bias voltage applied to the external modulator at a predetermined level required to provide the necessary separation between logic levels. The ABC circuit generates a dither signal and functions to digitally compare the phase of the dither signal to the phase of the optical signal produced by the external modulator. A phase comparator (e.g., D-type flip-flop) is used to monitor any drift in the optimum bias point of the modulator and generate an output correction signal by continuously adjusting the level of the DC bias voltage applied to the external modulator.

摘要： At least one dispersion compensating fiber (DCF) is utilized to compensate for chromatic dispersion of an externally modulated signal carried by at least one single mode, standard fiber optic cable. The self phase modulation (SPM) effect in the standard fiber is characterized by a pulse compression and associated pulse distortion when a 1550 nm wavelength signal is launched into the fiber. Because the SPM effect in the DCF fiber is characterized by a pulse broadening for the same signal, the DCF fiber is also utilized to compensate for the SPM effect in the standard fiber. To this end, the signal power launched into the DCF fiber is controlled such that precise compensation for the SPM effect in the standard fiber can be achieved. Control of the launching power is needed because the mode field diameter of the DCF fiber is smaller than that of the standard single mode fiber so that the DCF fiber experiences the SPM effect at a lower power than the single mode fiber.

摘要： A technique for reducing the power threshold at which stimulated brillouin scattering ("SBS") occurs within an optical fiber by directly modulating a conventional laser generating an optical signal propagated along that fiber. The modulation is accomplished by employing an alternating waveform to induce a dither upon the laser output. The specific frequency of the alternating waveform is chosen to be very much lower than the low frequency cut-off of any receiver coupled to the optical fiber, but sufficiently high enough to efficiently suppress the Brillouin gain. This dithering causes the laser to be frequency modulated, thereby broadening the effective linewidth of the laser output and increasing the SBS power threshold.
