Abstract A novel architecture with full-duplex direct communications(FDDC) between any two ONUs for optical access network is proposed in this paper. By designing combination switch(CS) ingeniously, the architecture is finished to realize FDDC between any two ONUs in wavelength division multiplexing passive optical networks(WDM-PONs). By utilizing interconnected optical fibers between ONUs, the network has achieved three-level protections(feeder optical fiber protection, distributed optical fiber protection and interconnected optical fiber protection). By constructing expansion module(EM), the network can be flexibly expanded and optimized, and the CapEx and OpEx of network can be greatly reduced. Finally, by the simulation and analysis, the effectiveness of the proposed architecture is demonstrated.

In this paper a hybrid optical code division multiple access (OCDMA) over wavelength division multiplexing (WDM) network is proposed to support large number of subscribers. The system combines two different techniques, namely OCDMA and WDM for supporting many subscribers simultaneously. We used modified double weight (MDW) codes as a signature address in designing the system because this code can accommodate more number of simultaneous active users under considerable standard bit error rate (e.g. ≤ 10-9). The induced MDW code for hybrid system can eliminate multiuser interference fully and increase the bit-error-rate performance compared to other codes at the same time. We ascertained by simulation results that the proposed scheme provides very good performance and enhance the network capability. Therefore, this system can be considered as a promising solution for the next generation optical access network.

Local Access

The penetration of optical-fibre technology into the local-access network may well occur by the economic provision of well-established services, such as basic telephony, over a shared-access optical architecture. The provision of new broadband services needs to be done without disruption to these basic (telephony) services. Wavelength-division multiplexing techniques allow the possibility of broadband upgrade on a shared-access network architecture without disturbing existing services. The nature of shared-access structures, although providing opportunities for the early economic provision of basic low-bit-rate services, gives rise to major implications for the requirements of the WDM technology used for upgrading to broadband operation. In this paper example network structures are examined in terms of possible upgrade strategies and the associated technological implications.
