| Abstract: | The functional structure of the typical Power Splitting Passive Optical Network (PSPON) is introduced in this paper. The current state-of-the-arts for various types of PON are presented, together with a detailed introduction of the working theory, frame structure and key technologies in PON. The characteristics of APON and EPON are analyzed and compared on the basis of standardization, bandwidth loss, transmission, and data processing etc. Through the comparison of traditional PSPON and WDM-PON, it is demonstrated that WDM-PON is superior to PSPON. The prospect for the future network development is also given. |
