Mathematical Verification for Transmission Performance of Centralized Lightwave WDM-RoF-PON with Quintuple Services Integrated in Each Wavelength Channel

摘要

Wavelength-division-multiplexing passive-optical-network (WDM-PON) has been recognized as a promising solution of the “last mile” access as well as multibroadband data services access for end users, and WDM-RoF-PON, which employs radio-over-fiber (RoF) technique in WDM-PON, is even a more attractive approach for future broadband fiber and wireless access for its strong availability of centralizedmultiservices transmission operation and its transparency for bandwidth and signalmodulation formats. As for multiservices development in WDM-RoF-PON, various system designs have been reported and verified via simulation or experiment till now, and the scheme with multiservices transmitted in each single wavelength channel is believed as the one that has the highest bandwidth efficiency; however, the correspondingmathematical verification is still hard to be found in state-of-theart literature. In this paper, system design and data transmission performance of a quintuple services integrated WDM-RoF-PON which jointly employs carriermultiplexing and orthogonalmodulation techniques, have been theoretically analyzed and verified in detail;moreover, the systemdesign has been duplicated and verified experimentally and the theory systemof suchWDM-RoF-PON scheme has thus been formed.
