Abstract

The feasibilit y for the applying of multimode fiber (MMF) in the future long haul, high bit rate, and large capacity PON is analyzed, and the strengths and weakness of MMF are summarized. Then, initiating from the waveguide theory in the weakly guiding fiber and neglecting the intra modal dispersion as well as nonlinearity, a simple model for multimode fiber is built, based on which analysis, research and comparison through simulation experiments on some performance improving techniques of MMF are made: offset launching, mode size changing, ring launching and feedback equalization. The simulation results demonstrated that the combination of field shaping (mainly ring launching) and feedback equalization can obviously improve the transmission properties of MMF, because of which, the 10 Gb/ s data can travel in the MMF for more than 1 km.

Abstract

Based on the multi-beam interference principle,a transmitting intensity expression of a Gaussian beam incidenting obliquely on an angle-tuned narrowband filter is derived.According to the result,the influence of the incidence angle on the transmission of a Gaussion beam is investigated theoretically.The calculation and experiment results show that the size of the transmitting beam spot is brodened obviously in oblique incidence.When the incident angle of the thin-film filter is relatively small,the position of the peak of the transmitting beam is shifted and the beam is not in Gaussian distribution.When the incident angle of the filter is relatively large,the transmitting beam consists of a series of space-separated beams.
