    摘要: The invention relates to an optical signal transmission system with phase modulation and the implementation method. The system adds a phase modulator in the optical signal-emitting module. The optical pulses after intensity modulation and a high-speed data stream are input to the phase modulator synchronously, where the optical pulses are modulated in phase according to the high-speed data stream into high-speed optical signals with chattering. According to the invention, the phase modulator added in the optical signal-emitting module modulates optical signals in phase, which has been modulated in intensity. Appropriate chattering modulation can depress effectively the non-linear effect in the transmission of optical pulses through the interaction between chromatic dispersion and non-linear effects. Thus, the power input of individual channels is increased effectively, and the passive relay regeneration distance is extended.

    摘要: The invention discloses a method for implementing power equalization of a DWDM system, comprises: Measure and calculate, respectively, a gain spectrum characteristic curve of an optical power booster amplifier unit and a loss spectrum characteristic curve of a loss device with related wavelengths in the DWDM system; Subtracting the loss spectrum characteristic curve from the gain spectrum characteristic curve to obtain a difference curve, taking the complement curve of the difference curve as a loss characteristic target curve of a GFF; Setting in the optical power booster amplifier unit a GFF having loss characteristic curve coinciding with the loss characteristic target curve. The invention synthetically considers gain spectrum of an optical power booster amplifier unit and loss spectrum of a loss device with relating wavelengths to define a loss characteristic curve which a GFF should have. In this way, optical power flatness of every channel is effectively guaranteed. Therefore, transmission link flatness of whole system is guaranteed, and channel optical power equalization property of a system is further improved.
