| Abstract: | The system architecture of WDMA EPON and its optoelectronic devices were introduced. A novel optical transmitter module with low cost and precise wavelength for upstream path in WDMA-EPON system was presented. Based on the hybrid integration of standard FP LD with narrow band filter of DWDM,a kind of laser diode with precise wavelength was used without wavelength locker. This DWDM laser was used in the ONU transmitter module of WDMA-EPON system. The output power>0.4?mW,extinction ratio>10?dB,and the bit rate of upstream transmission from 52?Mbit/s up to 622?Mbit/s continuously were gotten and eye diagrams met the mask requirements of IEEE 802.3 and ITU-T G.957. |
