After simple comparision between TDMA (Time Division Multiple Address) and WDMA(Wavelength Division Multiple Address),the thesis points out that WDMA instead of TDMA can avoid many difficult technology problems.

• 本文在对EPON中两种典型上行方式TDMA(时分多址)和WDMA(波分多址)进行简单比较之后,得出了:要想克服EPON中采用传统的TDMA上行方式的诸多技术难点,就必须采用WDMA上行方式的结论。
