High-speed optical time-division multiple-access (OTDMA) networks using optical signal processing

In this paper, we design high-speed optical fiber networks based on the tim e-division multiple-access (TDMA) technique. To achieve an ultrahigh throug hput, optical signal processing should be used in the network. We present a feasible scheme to implement optical TDMA networks, with the emphasis on o ptical clock distribution, synchronization, and optical time demultiplexing . Since the proposed network uses two wavelengths to carry optical TDMA and clock signals respectively, at each TDMA receiver slot synchronization is feasibly achieved by using simple optical delay lines to process the separa ted optical clock and TDMA signals. This in turn allows us to build a large -scale distribution network which is attractive for future HDTV broadcastin g applications. Using the proposed scheme also allows to implement a high-c apacity broadcast and select optical TDMA network for real-time data commun ications.
