Abstract
A novel architecture of hybrid WDM/OCDMA-PON employing two wavelength bands for two different groups of ONUs is proposed. OCDMA is overlayed on WDM channel in a single network and the total capacity of WDM/OCDMA-PON becomes 2m times larger than the traditional WDM-PON. Meanwhile, a C + L band ultra-broadband light source is used for upstream transmission, which can be seen as a cost-effective manner in FTTH. In simulation system, 1.25 Gb/s downstream and upstream data based on the architecture are transmitted with good performance. And the crosstalk penalties from adjacent code channels (at the same wavelength) are found to be little in upstream and downstream transmissions.
