Wdm Pon

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 centralized multiservices transmission operation and its transparency for bandwidth and signal modulation 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 corresponding mathematical verification is still hard to be found in state-of-the-art literature. In this paper, system design and data transmission performance of a quintuple services integrated WDM-RoF-PON which jointly employs carrier multiplexing and orthogonal modulation techniques, have been theoretically analyzed and verified in detail; moreover, the system design has been duplicated and verified experimentally and the theory system of such WDM-RoF-PON scheme has thus been formed.

Abstract Radio over Fiber (RoF) is one of the solutions to the “last mile” because of its bandwidth advantage offered by fiber and the mobility and flexibility of wireless systems. In this paper, the transmission performance of DSB, SSB and OCS with three modulation formats is established, and a new single-sideband modulation single-mode optical fiber transmission model is proposed, and simulated analysis is done to the system. In this paper, 40 GHz millimeter-wave signal was generated by external modulation, and the received signal is received by coherent demodulation. In this paper, Matlab and VPI are used for combine programming simulation, DCF method was used to compensate the chromatic dispersion. Through the analysis of dispersion performance, Q value and bit error rate, we can see that the modified SSB modulation has the best transmission performance for 120 km links.
