An overview on technologies for access nodes in ultra-fast OTDM photonic networks
In this paper, photonic technologies for the realization of high-capacity optical time-division multiplexed (OTDM) local and metropolitan area networks (LANs and MANs) are addressed including all-optical techniques such as ultra short pulse generation, all-optical clock recovery, optical multiplexing/demultiplexing, and optical packet compression/decompression. Furthermore, the new trends in high-speed electronics, data processing and optical interconnects are analyzed enabling the avoidance of the electronic processing bottleneck. By the use of both, high-speed electronics for implementing functions of higher complexity with higher level of parallelism and all-optical techniques for the realization of simple ultra fast (> 40 Gbit/s) medium access functions, a hybrid medium access node capable of handling high data rates can be designed.
