چکیده
This technical report details the 40Gb/s optical transmission testbed established at the Lightwave Communications Laboratory. This testbed provides a foundation for future experimental research on high-speed optical transmission systems and related performance issues. It will facilitate the research on advanced optical modulation formats and the comparison of optical systems with various optical fiber types. This experimental capability on 40Gb/s optical transmission systems will enable an independent assessment of new ideas of high-speed optical transmission and validate theoretical models.

Advanced Optical Modulation Formats in High-speed Lightwave System
In the next generation of lightwave systems, high speed datarate like 10Gb/s or 40Gb/s per channel is very attractive. In addition, to pack more channels into one single fiber, channel spacing is decreased from 200GHz to 50GHz or even smaller. The direct side-effect is that linear and nonlinear degrading effects will be severe in such high-speed lightwave systems. An optimal modulation format w...
