A 40Gb/s CWDM-TDM PON with a cyclic CWDM multiplexer/demultiplexer
01 January 2009
We demonstrate a 40-Gb/s hybrid CWDM-TDM PON with a novel remote node including a cyclic CWDM multiplexer/demultiplexer. The system uses commercially available 10-Gb/s 1.3-mum directly modulated laser transmitters upstream and 1.5-mum electroabsorption modulated laser transmitters downstream.
