  • an approximate analytic solution of the steady state brillouin scattering in single mode optical Fiber without neglecting the Attenuation Coefficient
    Optics Communications, 2009
    Co-Authors: Zhonghua Ou, Jianfeng Li, Lixun Zhang
    Abstract:

    The analysis of steady state Brillouin scattering in a long single mode optical Fiber is presented. Meanwhile, an approximate analytical functions of distributed Brillouin scattering and pump wave along the Fiber with the Fiber Attenuation Coefficient are obtained for the first time. A comparison is made among the analytical solutions with the Attenuation Coefficient, the analytical solutions without the Attenuation Coefficient and the exact numerical solutions. The results show that the analytical solutions with Fiber Attenuation Coefficient are more close to the numerical solutions, which can be used to describe the power distribution of the pump wave and the Stokes wave along the long distance single mode optical Fiber accurately.

  • Impact of Fiber parameters on EDFA and/or Raman amplified high-spectral-efficiency coherent WDM transmissions
    CUNY Academic Works, 2018
    Co-Authors: Leng Lufeng
    Abstract:

    The impact of Fiber properties is investigated for coherent systems employing polarization-division multiplexed high-level quadrature amplitude modulation, wavelength-division multiplexing, and erbium-doped Fiber amplifier and/or distributed Raman amplification. This is done by comparing the performances of Fiber links of various Attenuation Coefficients and effective areas via experimentally verified analytical methods. Results show that the excess noise, which originates at amplifiers compensating for the losses of filters and switches located between Fiber spans, can weaken or even diminish the performance enhancement brought about by lowering the Fiber Attenuation Coefficient, especially if distributed Raman amplification is employed. This leads to the difference in the link performance assessment between our analytical results and some previously published figures of merit (FOM). On the other hand, increasing the Fiber effective area results in the same amount of performance improvement regardless of the amplification scheme or the excess noise, which agrees with the FOMs. Since the larger effective area causes poorer pumping efficiency for systems employing distributed Raman amplification, a tradeoff between high performance and low power consumption needs to be determined for such systems
