摘要： The invention provide an optical fiber transmitter by both suppressing stimulated Brillouin scattering (SBS) effect and composite second-order (CSO) distortions at an optimized condition. The optical fiber transmitter includes a frequency modulator generating a first tone microwave with frequency f1 coupled to a laser source, and a phase modulator generating a second tone microwave with frequency f2 coupled to an external phase modulator, so as to broaden the modulated light spectrum. The first tone microwave with frequency f1 is set to be greater than 2 to 3 times of the highest frequency content in the modulating signals. The second tone microwave with frequency f2 is designed to be close to a harmonic frequency of f1 and no less than three times of f1. The first tone microwave with frequency f1 and a second frequency f2 are inputted to two power amplifiers, respectively, and then are respectively inputted to a laser source and an external phase modulator. These two power amplifiers are controlled by an microprocessor to automatically adjust a desired phase modulation index at 1.4 for the optical fiber transmitter with a repeaterless design or at an desired index depending on the desired transmission distance in a repeater design. The external phase modulator is coupled to a pare of fiber amplifiers for the repeaterless design or several pairs of fiber amplifers coupled in series for the repeater design. The last pair of the fiber amplifiers are coupled to optical receivers.

摘要： An optical fiber transmitter, which consists of a modulated optical source, a pre-distortion circuit, a chirped-fiber grating, an optical circulator or a coupler, is designed to transport subcarrier multiplexed (SCM) signals over a long transmission distance. Here the SCM signals include: analog amplitude-modulated vestigial-sideband (AM-VSB) cable television signals, digital quadrature-amplitude-modulated (QAM) signals, or orthogonal-frequency-division-multiplexed (OFDM) signals, or quadrature-phase-shift-keyed (QPSK) signals, etc. on radio-frequency (RF) or microwave carriers, and/or digital wireless signals on RF, microwave or millimeter wave carriers. The modulated light source can be a directly modulated laser diode, or an external LiNbO3 modulator with a continuous wave (CW) laser diode as the source, or an external electro-absorption modulator with an integrated CW laser diode. The chirped fiber grating has a chromatic dispersion characteristic which is opposite to that of the output transmission path, so that the majority of nonlinear distortions and carrier suppression caused by the optical fiber dispersion in a long-distance system can be significantly reduced. The pre-distortion circuit is used to correct the residual nonlinear distortions and eliminate the residual carrier suppression effect, which cannot be completely eliminated by the chirped fiber grating. The pre-distortion circuit is also used to suppress the residual nonlinear distortions and carrier suppression effects caused by the chirped fiber grating itself.
