We present here the main results for reach extension in passive optical network (PON) technologies. Both passive and active architectures integrating several multiplexing techniques are studied, and they provide promising results for the future generation of optical access networks. Extender boxes based on optical amplification and optical-electrical-optical (OEO) repeaters are evaluated over a standardized...
We propose to increase the reach and reduce the number of central offices by traffic aggregation of four G-PONs, achieving 10 Gbit/s downstream traffic. Upstream burst mode traffic at 1.25 Gbit/s is converted into continuous mode.
This paper considers the main technical challenges for optical access network deployment. Technological evolution of broadband optical networks is discussed with the need for adapting both metropolitan and access networks to the customer services demand evolution.
