Enabling technology for UDWDM access networks


  • Jan Lamperski Poznan University of Technology




In the presented paper we show an original concept of technology for access networks with ultra dense channel multiplexing using a multifrequency translator with an acousto-optic frequency shifter as a key module. As an example of functional capabilities of this module, original experimental results of a multifrequency optical source based on an erbium-doped fiber ring configuration are presented. Optical frequency comb generation with a very stable 1,5 GHz and 2.5 GHz frequency separation was obtained. We also proposed original configurations which allow the realization of network devices for gigahertz spacing channel multiplexing such as optical multiplexers, demultiplexers and optical add/drop multiplexers.
